Neoaplectana Steiner, 1929 a junior synonym of Steinernema Travassos, 1927 (Nematoda; Rhabditida)

Summary A type specimen of Steinernema kraussei and a population of this nematode from the type host were compared with three species of Neoaplectana. No characters were found to separate the two genera and so Neoplectana Steiner, 1929 is considered to be a junior synonym of Steinernema Travassos, 1927. Valid species now included within the genus Steinernema are: S. kraussei (Steiner, 1923) Travassos, 1927 (type species); S. glaseri (Steiner, 1929) n.comb.; S. feltiae (Filipjev, 1934) n.comb. and S. bibionis (Bovien, 1937) n.comb. A key is given to these four species and their junior synonyms are listed.     

The Lepocreadiidae (Digenea) of fishes of the north-east Atlantic: review of the genera Opechona Looss, 1907 and Prodistomum Linton, 1910

The genera Opechona Looss and Prodistomum Linton are redefined: the latter is re-established, its diagnostic character being the lack of a uroproct. Pharyngora Lebour and Neopechona Stunkard are considered synonyms of Opechona, and Acanthocolpoides Travassos, Freitas & Bührnheim is considered a synonym of Prodistomum. Opechona bacillaris (Molin) and Prodistomum [originally Distomum] polonii (Molin) n. comb. are described from the NE Atlantic Ocean. Separate revisions with keys to Opechona, Prodistomum and ‘Opechona-like’ species incertae sedis are presented. Opechona is considered to contain: O. bacillaris (type-species), O. alaskensis Ward & Fillingham, O. [originally Neopechona] cablei (Stunkard) n. comb., O. chloroscombri Nahhas & Cable, O. occidentalis Montgomery, O. parvasoma Ching sp. inq., O. pharyngodactyla Manter, O. [originally Distomum] pyriforme (Linton) n. comb. and O. sebastodis (Yamaguti). Prodistomum includes: P. gracile Linton (type-species), P. [originally Opechona] girellae (Yamaguti) n. comb., P. [originally Opechona] hynnodi (Yamaguti) n. comb., P. [originally Opechona] menidiae (Manter) n. comb., P. [originally Pharyngora] orientalis (Layman) n. comb., P. polonii and P. [originally Opechona] waltairensis (Madhavi) n. comb. Some species are considered ‘Opechona-like’ species incertae sedis: O. formiae Oshmarin, O. siddiqii Ahmad, 1986 nec 1984, O. mohsini Ahmad, O. magnatestis Gaevskaya & Kovaleva, O. vinodae Ahmad, O. travassosi Ahmad, ‘Lepidapedon’ nelsoni Gupta & Mehrotra and O. siddiqi Ahmad, 1984 nec 1986. The related genera Cephalolepidapedon Yamaguti and Clavogalea Bray and the synonymies of their constituent species are discussed, and further comments are made on related genera and misplaced species. The new combination Clavogalea [originally Stephanostomum] trachinoti (Fischthal & Thomas) is made. The taxonomy, life-history, host-specificity and zoogeography of the genera are briefly discussed.     

Molecular data reveal convergent reproductive strategies in iceryine scale insects (Hemiptera: Coccoidea: Monophlebidae), allowing the re-interpretation of morphology and a revised generic classification

Abstract The scale insect tribe Iceryini (Coccoidea: Monophlebidae) is a group of relatively large and polyphagous insects found worldwide. Currently, the tribe contains about 80 named species placed in seven genera, which are diagnosed largely on features associated with egg protection. We reconstruct the phylogeny of the Iceryini on the basis of nucleotide sequence data from nuclear ribosomal (18S and D2, D3 and D10 regions of 28S) and protein‐coding (histone H3) gene regions of 40 iceryine species representing six of the seven genera and seven outgroup taxa, mostly from two other tribes of Monophlebidae. Bayesian and maximum parsimony analyses recover a monophyletic tribe and clades that correspond more to geography than to the existing morphology‐based classification. Gueriniella Fernald is sister to the rest of the Iceryini and the genera Crypticerya Cockerell, Icerya Signoret and Steatococcus Ferris are not monophyletic. Our data imply that the distinctive iceryine reproductive strategies, such as protecting eggs in a waxy ovisac or inside a marsupium, are poor indicators of relationships. On the basis of molecular relationships and the re‐examination of morphological characters, we recognize only five genera of Iceryini –Crypticerya, Echinicerya Morrison, Gigantococcus Pesson & Bielenin, Gueriniella and Icerya – and substantially revise the generic concepts of Crypticerya, Gigantococcus and Icerya. We provide a key to the genera based on adult females. We redescribe and illustrate the adult female and first‐instar nymph of the type species Crypticerya rosae (Riley & Howard), Echinicerya anomala Morrison, Gigantococcus maximus (Newstead) (adult female only), Gueriniella serratulae (Fabricius) and Icerya seychellarum (Westwood). We recognize Auloicerya Morrison as a junior synonym ( syn.n. ) of Icerya, and transfer the two Auloicerya species to Icerya as I. acaciae (Morrison & Morrison) comb.n. and I. australis Maskell comb.rev. We recognize Steatococcus and Proticerya Cockerell as junior synonyms ( syn.n. ) of Crypticerya. From Steatococcus, we transfer five species to Crypticerya [C. mexicana Cockerell & Parrott comb.rev. , C. morrilli (Cockerell) comb.n. , C. tabernicola (Ferris) comb.n. , C. townsendi Cockerell comb.rev. , C. tuberculata (Morrison) comb.n. ], four species to Gigantococcus [Gi. euphorbiae (Brain) comb.n. , Gi. gowdeyi (Newstead) comb.n. , Gi. madagascariensis (Mamet) comb.n. , Gi. theobromae (Newstead) comb.n. ] and three species to Icerya [I. assamensis (Rao) comb.n. , I nudata Maskell comb.rev. , I. samaraia (Morrison) comb.n. ]. From Icerya, we transfer 14 species to Crypticerya [C. brasiliensis (Hempel) comb.n. , C. colimensis (Cockerell) comb.n. , C. flava (Hempel) comb.n. , C. flocculosa (Hempel) comb.n. , C. genistae (Hempel) comb.n. , C. littoralis (Cockerell) comb.n. , C. luederwaldti (Hempel) comb.n. , C. minima (Morrison) comb.n. , C. montserratensis (Riley & Howard) comb.n. , C. palmeri (Riley & Howard) comb.n. , C. rileyi (Cockerell) comb.n. , C. similis (Morrison) comb.n. , C. subandina (Leonardi) comb.n. , C. zeteki (Cockerell) comb.n. ] and nine species to Gigantococcus [Gi. alboluteus (Cockerell) comb.n. , Gi. bimaculatus (De Lotto) comb.n. , Gi. brachystegiae (Hall) comb.n. , Gi. longisetosus (Newstead) comb.n. , Gi. nigroareolatus (Newstead) comb.n. , Gi. pattersoni (Newstead) comb.n. , Gi. schoutedeni (Vayssière) comb.n. , Gi. splendidus (Lindinger) comb.n. , Gi. sulfureus (Lindinger) comb.n. ]. From Crypticerya, we transfer seven species to Icerya [I. clauseni (Rao) comb.n. , I. jacobsoni Green comb.rev. , I. jaihind (Rao) comb.n. , I. kumari (Rao) comb.n. , I. mangiferae (Tang & Hao) comb.n. , I. natalensis (Douglas) comb.rev. , I. nuda Green comb.rev. ] and five species to Gigantococcus [Gi. bicolor (Newstead) comb.n. , Gi. cajani (Newstead) comb.n. , Gi. caudatus (Newstead) comb.n. , Gi. ewarti (Newstead) comb.n. , Gi. rodriguesi (Castel‐Branco) comb.n. ]. Both I. hyperici (Froggatt) and Palaeococcus dymocki (Froggatt) are syn.n. of I. nudata (all previously placed in Steatococcus). We recognize I. maynei Vayssière as a syn.n. of Gi. nigroareolatus, I. tremae Vayssière as a syn.n. of Gi. schoutedeni and I. townsendi plucheae Cockerell as a syn.n. of C. townsendi. We revalidate the species name I. crocea Green stat.reval. In addition, we transfer I. taunayi Hempel to Laurencella Foldi (Monophlebidae: Llaveiini) as L. taunayi (Hempel) comb.n. Four species, Coccus hirticornis Boyer de Fonscolombe, I. chilensis Hempel, I. insulans Hempel and I. paulista Hempel, are considered incertae sedis. We designate lectotypes for C. rosae, E. anomala and I. candida (a junior synonym of I. seychellarum). Following this revision, we recognize 74 species of Iceryini, distributed as follows: 22 in Crypticerya, one in Echinicerya, 19 in Gigantococcus, two in Gueriniella and 30 in Icerya.     

Towards a natural classification of the subtribe Philonthina (Coleoptera: Staphylinidae: Staphylinini): a phylogenetic analysis of the Neotropical genera

Philonthina, the largest subtribe of the rove beetle tribe Staphylinini, is a hyperdiverse group in the Neotropical Region, accounting for about half of the genera of the subtribe. Despite such diversity, Neotropical Philonthina have never been analysed phylogenetically, deterring formulation of a modern classification of the Staphylinini. A cladistic analysis of Neotropical Philonthina was performed based on 110 morphological characters and 77 terminal taxa. Representatives of Philonthina from other regions and other main lineages of Staphylinini, Arrowinini and Platyprosopini were included to test their relationships with Neotropical Philonthina. The major results are the monophyly of 11 of the 17 endemic Neotropical genera of Philonthina, the placement of Holisus Erichson (Hyptiomina) into this clade showing a sister group relationship to myrmecophile genera, and the position of Erichsonius Fauvel outside of Philonthina within Staphylinini. Six of the current seven species of Endeius Coiffait & Sáiz group with Neotropical species of Philonthus Stephens. The separation of Gondwana about 65 my and major landscape modifications in the vast interior of northern South America during the past 25 my is proposed to explain the evolution of the endemic Neotropical genera of Philonthina. The following taxonomic changes are proposed: Erichsonius Fauvel, 1874 now placed as incertae sedis in Staphylinini; Endeius Coiffait & Sáiz, 1968, n.syn. of Philonthus Stephens, 1929 and Endeius nitidipennis (Solier, 1849) placed as incertae sedis in Philonthina. The following new combinations are proposed: Philonthus franzi (Sáiz, 1971), comb.n. , Philonthus loensis (Coiffait & Sáiz, 1968), comb.n. , Philonthus lugubris (Sáiz, 1971), comb.n. , Philonthus ovaliceps (Coiffait, 1981), comb.n. , Philonthus punctipennis (Solier, 1849), comb.res. and Philonthus subpunctipennis (Coiffait & Sáiz, 1968), comb.n. Philonthus herberti, n.nov., is proposed for Philonthus franzi Schillhammer, 1998 , which is a junior secondary homonym of Philonthus franzi (Sáiz, 1971).     

A taxonomic revision of the Nematotaeniidae Lühe, 1910 (Cestoda: Cyclophyllidea)

A taxonomic revision of the Nematotaeniidae, involving the examination of over 400 specimens, was undertaken. Some new taxonomic characters have been introduced to allow distinction of the various species. The family contains 18 recognized species in four genera. The genusNematotaenia Lühe, 1910 contains four species, namelyN. chantalae Dollfus, 1957,N. dispar (Goeze, 1782) Lühe, 1910,N. hylae Hickman, 1960, andN. tarentolae Lopez-Neyra, 1944.N. kashmirensis Fotedar, 1966,N. dollfusi, Yuen & Fernando, 1974 andN. viride Mokhtar-Maamouri & Chakroun, 1984 are considered junior synonyms ofN. dispar. N. aurangabadensis Chincholikar & Shinde, 1975,N. lopezneyrai Soler, 1945 andN. mabuiae Shinde, 1968 are consideredspecies inquirendae: the latter species probably belongs in the genusOochoristica Lühe, 1898 (Anoplocephalidae: Linstowiinae). The genusCylindrotaenia Jewell, 1916 is shown to possess two testes per segment and not one as originally proposed:Baerietta Hsü, 1935 is consequently synonymized withCylindrotaenia. Cylindrotaenia is divided into five species-groups on the basis of adult morphology. The first group contains two American species, namelyC. americana Jewell, 1916 andC. idahoensis (Waitz & Mehra, 1961) n. comb. The second group contains species from Australia and New Zealand, namelyC. allisonae (Schmidt, 1980), n. comb.,C. criniae (Hickman, 1960) n. comb.,C. decidua (Ainsworth, 1985) n. comb.,C. hickmani (Jones, 1985) n. comb. andC. minor (Hickman, 1960) n. comb. A third species group consists ofC. jaegerskioeldi (Janicki, 1926) n. comb.,C. magna n. sp. andC. philauti Crusz & Sanmugasunderam, 1971 and occurs in Africa, Sri Lanka and Japan. The fourth group, apparently restricted to Japan, contains a single species,C. japonica (Yamaguti, 1938) n. comb. The fifth group containsC. montana (Yamaguti, 1954) n. comb. and occurs in Japan and Tibet.C. quadrijugosa Lawler, 1939 is synonymized withC. americana, andBaerietta claviformis Yamaguti, 1954 is synonymized withC. japonica. C. baeri (Hsü, 1935) n. comb.,C. chilensis (Puga & Franjola, 1983) n. comb.,C. diana (Helfer, 1948) Lehmann, 1960,C. malayi (Yuen & Fernando, 1974) n. comb. andC. roonwali Nama, 1972 arespecies inquirendae. The genusDistoichometra, Dickey 1921 contains a single species, namelyD. bufonis Dickey, 1921.D. kozloffi Douglas, 1958 andBaerietta enteraneides (Helfer, 1948) Yamaguti, 1959 are reduced to synonymy withD. bufonis. Bitegmen n. g. is proposed to accomodate a single species,B. gerrhonoti (Telford, 1965) n. comb., which was previously included in the genusBaerietta. The present distribution of the Nematotaeniidae is largely related to that of their anuran hosts. Nematotaeniids probably arose in Gondwanaland.     

Dactylogyridean monogeneans of the siluriform fishes of the Old World

This is a catalogue and discussion of the known dactylogyridean monogenean genera of siluriform fishes of the Old World. Of a total of 38 nominal genera, only 19 are considered valid. Seventeen of these 19 genera are currently in the Ancyrocephalidae (containing the Ancyrocephalinae and Ancylodiscoidinae), whilst the other two (Neocalceostoma and Neocalceostomoides) are in the Neocalceostomatidae. The 17 genera are Anchylodiscus, Ancylodiscoides, Bagrobdella, Bifurcohaptor, Bychowskyella, Chauhanellus, Cornudiscoides, Hamatopeduncularia, Mizelleus, Paraquadriacanthus, Pseudancylodiscoides, Protoancylodiscoides, Quadriacanthus, Schilbetrema, Schilbetrematoides, Synodontella and Thaparocleidus. Clariotrema Long, 1981 and Neobychowskyella Ma, Wang & Li, 1983 are considered synonyms of Bychowskyella Akhmerov, 1952, Anacornuatus Dubey, Gupta & Agarwal, 1992 is considered a synonym of Quadriacanthus Paperna, 1961, Mizellebychowskia Gupta & Sachdeva, 1990 is considered a synonym of Neocalceostoma Tripathi, 1959 and Hargitrema Tripathi, 1959 is treated as a synonym of Hamatopeduncularia Yamaguti, 1953. It is proposed that the Ancylodiscoidinae be raised to family status within the order Dactylogyridea to accommodate these 17 `ancyrocephalid' genera from siluriforms, together with Malayanodiscoides and Notopterodiscoides from notopterids. A key and the diagnostic characteristics of the 19 recognised dactylogyridean genera from catfishes plus two from notopterids, together with a list of species and synonyms, are included. New combinations made in this work are Thaparocleidus avicularia (Chen, 1987) n. comb., T. calyciflorus (Chen, 1987) n. comb., T. choanovagina (Luo & Lang, 1981) n. comb., T. dissimilis (Chen, 1988) n. comb., T. leiocassis (Reichenbach-Klinke, 1959) n. comb., T. meticulosa (Chen, 1987) n. comb., T. parasoti (Zhao & Ma, 1999) n. comb., T. persculpus (Chen, 1987) n. comb., T. valga (Chen, 1987) n. comb. and T. wulingensis (Yao & Wang, 1997) n. comb. [all from Silurodiscoides] and Bychowskyella glyptothoraci (Ma, Wang & Li, 1983) n. comb. [from Neobychowskyella].     

The first phylogenetic study of Mesembrinellidae (Diptera: Oestroidea) based on molecular data: clades and congruence with morphological characters

The Mesembrinellidae (Diptera: Oestroidea) comprise a small group of strictly Neotropical calyptrate flies, with 36 described species. The group has often been treated as a subfamily of Calliphoridae, but there is growing evidence that it corresponds to a distinct Oestroidea lineage. Internal relationships have so far been addressed based only on morphology, with results lacking resolution and support. This is the first molecular phylogeny for the group, which is based on the analyses of 80 terminal taxa (22 mesembrinellid and 28 outgroup species) and 5 molecular markers (ITS2, 28S, COI, COII and 16S). Maximum‐parsimony, maximum‐likelihood and Bayesian inference methods were used, the latter two with partitioning strategies considering codon position and secondary structure information. Results corroborate the Mesembrinellidae as a monophyletic lineage inside Oestroidea. Three clades were consistently recovered: (1) (Laneella + Mesembrinella patriciae); (2) (Mesembrinella (excluding M. patriciae)  + Eumesembrinella); and (3) (Huascaromusca + Giovanella). Re‐examination of the female reproductive tract of M. patriciae revealed a Laneela‐type spermatheca, which corroborates the position of the species recovered in the molecular phylogenetic analyses. Mesembrinella and Huascaromusca are in all cases paraphyletic with regards to Eumesembrinella and Giovanella, respectively. These latter two genera should, thus, be seen as subjective junior synonyms.     

Taxonomic review of Bourguyiinae,cladistic analysis,and a new hypothesis of biogeographic relationships of the Brazilian Atlantic Rainforest (Arachnida: Opiliones,Gonyleptidae)

The subfamily Bourguyiinae Mello‐Leitão, 1923 (Gonyleptidae) is revised, and both phylogenetic and biogeographic hypotheses are proposed. Bourguyiinae is monophyletic, and is the sister group of the remainder of the Gonyleptidae species used for analysis, except for the Metasarcinae, which collectively is the sister group of Metavononoides orientalis Mello‐Leitão, 1923 (Cosmetidae). Bourguyiinae is divided into two genera: Bourguyia (six species) and Asarcus (four species). The genus‐level synonyms proposed here are as follows: Caldasius, Styloleptes, and Stylopisthos are junior synonyms of Bourguyia; Bogdana, Cnemoleptes, and Opisthoplites are junior synonyms of Asarcus. The species synonyms proposed here are as follows: Afranius amarali Mello‐Leitão, 1934 is a junior synonym of Bourguyia albiornata Mello‐Leitão, 1923 ; Drastus hamatus Roewer, 1943 and Styloleptes conspersus Piza, 1943 are junior synonyms of Bourguyia trochanteralis Roewer, 1930 ; Asarcus corallipes Simon, 1879 , Asarcus lutescens Sørensen, 1884 , Asarcus pallidus Mello‐Leitão, 1923 , and Opisthoplites ypsilon Sørensen, 1884 are junior synonyms of Asarcus longipes Kollar in Koch, 1839 ; Asarcus nigriconspersus Soares & Soares, 1945 is a junior synonym of Asarcus ingenuus Melo‐Leitão, 1940. New species described are: Bourguyia bocaina sp. nov. (Serra da Bocaina, São José do Barreiro, São Paulo), Bourguyia vinosa sp. nov. (E.B. Boracéia, Salesópolis, São Paulo), and Asarcus putunaberaba sp. nov. (Parque Nacional do Caparaó, Alto Caparaó, Minas Gerais). Bourguyiinae is endemic to the Atlantic Rainforest in the Brazilian states of Minas Gerais, Rio de Janeiro, São Paulo, and Paraná. Based on the modified data matrix of Pinto‐da‐Rocha et al., we propose a new biogeographical hypothesis for the Atlantic Rainforest. We suggest that Bourguyiinae species were originally distributed from the coastal region of Paraná to the north of Rio de Janeiro and south‐east of Minas Gerais, with subsequent dispersals both to northern and southern areas. © 2009 The Linnean Society of London, Zoological Journal of the Linnean Society, 2009, 156 , 319–362.     

Revision of Entomelas Travassos, 1930 (Nematoda: Rhabdiasidae) with a review of genera in the family

Summary Entomelas entomelas (Dujardin, 1845) Travassos, 1930, the type species of Entomelas, is redescribed based on specimens from Anguis fragilis and Ophisaurus apodus. The generic diagnosis is emended. E. dujardini (Maupas, 1916) Travassos, 1930, Paraentomelas kazachstanika (Sharpilo & Vakker, 1972) Sharpilo, 1976 and Hexadontophorus ophisauri Kreis, 1939 are synonymized with E. entomelas and the genera Paraentomelas and Hexadontophorus fall as synonyms of Entomelas. Kurilonema Szczerbak & Sharpilo, 1969 is synonymized with Entomelas and the type species, K. markovi, is reclassified as Entomelas markovi (Szczerbak & Sharpilo, 1969) n. comb. Entomelas cruszi n. sp. is described from agamid lizards of Sri Lanka. The genera in the Rhabdiasidae are reviewed and a key is provided. Ophiorhabdias Yamaguti, 1943 and Shorttia Singh & Ratnamala, 1977 are designated synonyms of Rhabdias Stiles & Hassall, 1905. ac]19790201     

Molecular phylogenetic analyses indicate paraphyly of the genus Hybomys (Rodentia: Muridae): Taxonomic implications

Widely distributed in Guineo‐Congolian forests, the genus Hybomys is represented by two species complexes (univittatus and trivirgatus), each restricted to one distinct forest block. In the last revision, these two species complexes were considered as distinct subgenera (Hybomys and Typomys). Previous morphological and karyological studies identified an important divergence between these two subgenera and raised the question of their taxonomic status (subgenus or genus). The number of species within this genus is also a matter of discussion: nine forms were described but only six (H. badius, H. basilii, H. lunaris, H. planifrons, H. trivirgatus, and H. univitttatus) are currently recognized as distinct species, the three others (H. pearcei, H. eisentrauti, and H. rufocanus) being considered as synonyms. The monophyly of the genus and its species have never been previously investigated with DNA sequence data. In this study, we combined mitochondrial and nuclear data (for a total of 3,264 nucleotide characters) to test the monophyly of Hybomys and to assess the specific status of H. eisentrauti and H. rufocanus. Our results highlight the paraphyly of the genus: members of the H. univittatus species complex appeared closely related to the genera Stochomys and Dephomys; representatives of H. trivirgatus are the sister clade of the node grouping Stochomys, Dephomys and member of the H. univittatus species complex. Combined with previous morphological findings, our results suggest that Typomys and Hybomys should be considered as two distinct genera. Based on tree topology and genetic distances, we propose to consider H. rufocanus as a valid species, distinct from H. univittaus, and to consider H. badius and H. eisentrauti as junior synonyms of H. rufocanus.     

Molecular phylogeny and taxonomic revision of the genera Baudinella Thiele, 1931, Retroterra Solem, 1985 and Molema Köhler, 2011 endemic to the coastal Kimberley,Western Australia (Gastropoda,Camaenidae)

Baudinella Thiele, 1931, Retroterra Solem, 1985 and Molema Köhler, 2011 are three genera of camaenid land snail endemic to coastal regions of the Western Australian Kimberley. Each of these genera has fairly distinct shells, but all exhibit a rather similar configuration of the reproductive system, which is characterized by lack of a penial sheath and presence of an elongated and coiled bursa copulatrix. By combining comparative morphology of shell and penial anatomy with analyses of the mitochondrial DNA fragments 16S rRNA (16S) and cytochrome c oxidase subunit 1 (COI), the phylogenetic relationships amongst representative species of these genera are addressed to test the monophyly of taxa and to identify new species. Our results show that all three genera are members of a single camaenid radiation. Five new species are described: two new species of Baudinella, B. magna n. sp. from the Institute and Montesquieu Archipelagos and B. margaritata n. sp. from Pitta Gorge in the Prince Regent Reserve, one new species of Molema, Molema tenuicostata n. sp., from near Talbot Bay, and two new species of Retroterra, R. dichroma, and R. nana, from the Prince Regent Reserve.     

Phylogeny of three choreotrich genera (Protozoa,Ciliophora, Spirotrichea), with morphological,morphogenetic and molecular investigations on three strobilidiid species

Liu, W., Yi, Z., Lin, X., Warren, A. & Song, W. (2012). Phylogeny of three choreotrich genera (Protozoa, Ciliophora, Spirotrichea), with morphological, morphogenetic and molecular investigations on three strobilidiid species. —Zoologica Scripta, 41, 417–434. The phylogenetic relationships among three strobilidiid genera, namely Strobilidium, Rimostrombidium and Pelagostrobilidium, are investigated using a combination of morphological, morphogenetic and molecular data. The results indicate that all three genera belong to the same lineage, in which Rimostrombidium evolved first and Strobilidium and Pelagostrobilidium derived later. Improved genus diagnoses for Rimostrombidium and Pelagostrobilidium are supplied. The curved kinety 2 and the caudal spiralling of some somatic kineties are confirmed as generic characters for Pelagostrobilidium and Strobilidium, respectively. In addition, the morphology and morphogenesis of three species, namely R. veniliae ( Montagnes & Taylor, 1994 ) Petz et al., 1995 , P. paraepacrum sp. n. and P. minutum sp. n., isolated from the South China Sea are described. Pelagostrobilidium paraepacrum sp. n. is characterized by the presence of six somatic kineties, 30–32 external and two internal membranelles. Pelagostrobilidium minutum sp. n. is characterized by its extremely small body size, four somatic kineties, and in having one internal and 19–21 external membranelles. Rimostrombidium conicum Kahl, 1932 is transferred to the genus Pelagostrobilidium as P. conicum (Kahl, 1932) comb. nov.     

Total evidence phylogenetic analysis and reclassification of Euschistus Dallas within Carpocorini (Hemiptera: Pentatomidae: Pentatominae)

Robust phylogenetic hypotheses have become key for studies addressing the evolutionary biology and ecology of various groups of organisms. In the species‐rich heteropteran superfamily Pentatomoidea, phylogenies at lower taxonomic levels are still scarce and mostly employ exclusively morphological data. In this study, we conducted a total evidence phylogeny focusing on the tribe Carpocorini (Pentatomidae), using morphological data and four DNA markers (COI, Cytb, 16S and 28S rDNA; ～2330 bp; 32 taxa) in order to investigate the relationships within Euschistus Dallas, one of the most speciose pentatomid genera, and between Euschistus and related genera. Our hypotheses generated by maximum likelihood and Bayesian inference show that the current taxonomic composition and classification of Euschistus and allied genera are in need of revision. Euschistus was recovered as nonmonophyletic, with the subgenera forming four independent lineages: Euschistus (Euschistus) and Euschistus (Lycipta) Stål are sister groups; Euschistus (Euschistomorphus) Jensen‐Haarup is more closely related to Dichelops Spinola and Agroecus Dallas; and Mitripus Rolston is divided into two clades closely related to Sibaria Stål and Ladeaschistus Rolston. We chose not to change the classification of E. (Euschistomorphus) until further data become available, and propose to split Euschistus into three genera with the exclusion of Euschistus (Mitripus) and all of its species. Here we elevate Mitripus to genus rank to include M. acutus comb.n. , M. convergens comb.n. and M. legionarius comb.n. , and propose Adustonotus Bianchi gen.n. to include A. anticus comb.n. , A. latus comb.n. , A. tauricornis comb.n. , A. grandis comb.n. , A. hansi comb.n. , A. paranticus comb.n. , A. irroratus comb.n. and A. saramagoi comb.n. We also provide identification keys to the genera Adustonotus gen.n. , Ladeaschistus, Mitripus n. rank and Sibaria, here defined as the Mitripus genus group, and to the species of Mitripus and Adustonotus gen.n. Our results provide insights into the current status of the classification of the Pentatomidae, suggesting the need for phylogenetic analyses at different taxonomic levels within stink bugs.

Taxonomic review and phylogenetic inference elucidate the evolutionary history of Mesozoic Procercopidae,with new data from the Cretaceous Jehol Biota of NE China (Hemiptera,Cicadomorpha)

The Mesozoic family Procercopidae is widely treated as the ancient group of Cercopoidea and a transitional unit to recent lineages, but its evolution and diversity are vague due to fragmentary fossil record and confusing taxonomic history. Herein, an extensive taxonomic review of Procercopidae is presented and some new fossils are reported from the Lower Cretaceous Yixian Formation of NE China. As a result, Chengdecercopis Hong, 1983 is transferred from Procercopidae to Sinoalidae; Procercopis longipennis Becker-Migdisova, 1962 and P shawanensis Zhang, Wang and Zhang, 2003 are transferred to Procercopina Martynov, 1937, resulting in Procercopina longipennis (Becker-Migdisova, 1962), comb. n. and P shawanensis (Zhang, Wang and Zhang, 2003), comb. n.; Luanpingia senjituensis Hong, 1984 is transferred to Stellularis Chen, Yao and Ren, 2015, leading to Stellulari senjituensis (Hong, 1984), comb. n.; Anthoscytina macula Hu, Yao and Ren, 2014 is transferred to Sinocercopis Hong, 1982, and Sunoscytinopteris (Scytinopteridae) and Cathaycixius (Cixiidae) are treated as junior homonym names of Sinocercopis, leading to Sinocercopis macula (Hu, Yao and Ren, 2014), comb. n., S lushangfenensis (Hong, 1984), comb. n., S pustulosis (Ren, 1995), comb. n., and S trinervis (Ren, 1995), comb. n. Additionally, two new species are erected: Stellularis bineuris Chen and Wang, sp. n. and S minutus Chen and Wang, sp. n. Our cladistic analysis based on wing (tegmen and hind wing) characteristics recovers the high-level relationships within Cercopoidea: Sinoalidae + (Procercopidae + (Cercopionidae + modern cercopoids)). Within the family Procercopidae, the cladistic analysis reveals that the Middle to Late Jurassic Titanocercopis and Jurocercopis and the Cretaceous Cretocercopis occupy the basal position, and a gradual change in wing venation can be recognized from the Early Jurassic Procercopis and Procercopina to the Jurassic Anthoscytina, and then to the Cretaceous Stellularis and Sinocercopis. The two Cretaceous genera, sharing wing traits with extant cercopoids, likely represent transitional forms between Procercopidae and recent Cercopoidea; however, they are very similar to their Jurassic relatives in body structures, suggesting it is applicable to attribute them to Procercopidae. Furthermore, our analysis suggests that the extinction of Procercopidae and the origin and early diversification of modern Cercopoidea approximately coincided with the rise and explosive radiation of angiosperms in the late Early Cretaceous and onwards.     

Phylogeny and genus-level classification of mantellid frogs (Amphibia, Anura)

We propose a novel classification of frogs in the family Mantellidae, based on published phylogenetic information and on a new analysis of molecular data. Our molecular tree for 53 mantellid species is based on 2419 base pairs of the mitochondrial 12S rRNA, 16S rRNA, tRNAVal and cytochrome b genes, and of the nuclear rhodopsin gene. Because the genus Mantidactylus Boulenger sensu lato is confirmed to be paraphyletic with respect to Mantella Boulenger, and is highly diverse in morphology and reproductive biology, we propose to partition Mantidactylus into seven genera by elevating four subgenera to genus rank (Blommersia Dubois, Guibemantis Dubois, Spinomantis Dubois, and Gephyromantis Methuen) and creating two new genera (Boehmantis gen. n. and Wakea gen. n.). In addition, we create the new subgenera Boophis (Sahona) subgen. n., Gephyromantis (Duboimantis) subgen. n., G. (Vatomantis) subgen. n., and Mantidactylus (Maitsomantis) subgen. n. The following species are transferred to Spinomantis, based on their phylogenetic relationships: S. elegans (Guibé) comb. n. (formerly in Mantidactylus subgenus Guibemantis); S. bertini (Guibé) comb. n. and S. guibei (Blommers-Schlösser) comb. n. (both formerly in Mantidactylus subgenus Blommersia); S. microtis (Guibé) comb. n. (formerly in Boophis Tschudi). Within Boophis, the new B. mandraka species group and B. albipunctatus species group are established. Boophis rhodoscelis (Boulenger) is transferred to the B. microtympanum group. The following five species are revalidated: Mantidactylus bellyi Mocquard and M. bourgati Guibé (not junior synonyms of M. curtus (Boulenger)); M. cowanii (Boulenger) (not syn. M. lugubris (Duméril)); M. delormei Angel (not syn. M. brevipalmatus Ahl); Mantella ebenaui (Boettger) (not syn. M. betsileo (Grandidier)). The new classification accounts for recent progress in the understanding of the phylogeny and natural history of these frogs, but it is still tentative for a number of species. Future modifications may be necessary, especially as concerns species now included in Gephyromantis and Spinomantis.Full article published online at: http://www.senckenberg.de/odes/06-11.htm     

Phylogeny and classification of the Elachistidae s.s. (Lepidoptera: Gelechioidea)

Abstract. The classification of the gelechioid family Elachistidae (Lepidoptera) is revised on the basis of a phylogenetic analysis. Pee-Wee analysis of 131 characters of adult and pupal morphology and larval mode of life, coded for seventy elachistid species, results in a classification with three recognized genera: Perittia, Stephensia and Elachista. Elachista is further divided into four subgenera. The phylogenetic relationships of the genera and subgenera are (Perittia (Stephensia ((E. sg. Dibrachia (E. sg. Hemiprosopa, E. sg. Aphelosetia)) (E. sg. Elachista)))). Twenty-four new generic synonyms and thirty-eight new generic combinations of species are proposed. A checklist is given for the species of Elachistidae in their revised generic combinations, including nine new synonymies. Due to secondary homonymy, Elachista dasycara nom. n. is proposed as a new name for Eurynome albella Chambers.     

Reclustering the cluster flies (Diptera: Oestroidea,Polleniidae)

A phylogenetic analysis of selected oestroid taxa based on 66 morphological traits and sequences from three nuclear protein‐coding genes (CAD, MAC, MCS) resolved the composition and phylogenetic position of the former subfamily Polleniinae of the Calliphoridae – here resurrected at family rank as Polleniidae Brauer & Bergenstamm, 1889 stat. rev. Six species are transferred from the family Rhinophoridae to the Polleniidae: the Palaearctic genus Alvamaja Rognes, along with its single species Alvamaja chlorometallica Rognes, and five Afrotropical species comprising the carinata‐group formerly in the genus Phyto Robineau‐Desvoidy but here assigned to genus Morinia Robineau‐Desvoidy, i.e. M. carinata (Pape, 1987) comb.n. , M. lactineala (Pape, 1997) comb.n. , M. longirostris (Crosskey, 1977) comb.n. , M. royi (Pape, 1997) comb.n. and M. stuckenbergi (Crosskey, 1977) comb.n. The Polleniidae are monophyletic and, in agreement with most recent phylogenetic reconstructions, sister to the Tachinidae. The female of A. chlorometallica and a new species of Morinia of the carinata‐group (Morinia tsitsikamma sp.n. from South Africa) are described.

Diplectanids infesting the gills of the barramundi Lates calcarifer (Bloch) (Perciformes: Centropomidae), with the proposal of Laticola n. g. (Monogenoidea: Diplectanidae)

Four species of the Monogenoidea, Laticola lingaoensis n. sp., L. latesi (Tripathi, 1957) n. comb. [previously Pseudorhabdosynochus latesi (Tripathi, 1957) Kritsky & Beverley-Burton, 1986], L. paralatesi (Nagibina, 1976) n. comb. [previously Diplectanum paralatesi Nagibina, 1976] and Diplectanum penangi Liang & Leong, 1991, are reported from the gills of Lates calcarifer (Centropomidae) from the South China Sea (new geographical records for L. latesi and D. penangi). Collections from off Bathurst Island, Northern Territory, Australia, represent a new geographic record for L. paralatesi; Chilka Lake, Orissa, India, is established as the type-locality for L. latesi. Laticola n. g. (Diplectanidae) is proposed for species with a spoon-shaped copulatory organ with two to four concentric incomplete ridges in the base. Laticola lingaoensis, the type-species of Laticola, is described, and L. latesi and L. paralatesi are redescribed based on specimens from the South China Sea. Pseudorhabdosynochus monosquamodiscusi Balasuriya & Leong, 1995 and Pseudorhabdosynochus yangjiangenesis Wu & Li, 2005 are considered junior subjective synonyms of L. latesi and L. paralatesi, respectively.
