Parachordatortilis n. g. (Nematoda: Spirurida: Acuariidae), with a redescription of P.mathevossianae (Petrov & Chertkova, 1950) n. comb., a parasite of Falco tinnunculus L. (Aves: Falconiformes)

Parachordatortilis n. g. is proposed as a monotypic genus for Parachordatortilis mathevossianae (Petrov & Chertkova, 1950) n. comb. (Spirurida, Acuariidae), previously Dispharynx mathevossianae Petrov & Chertkova, 1950. The new genus can be distinguished from all other acuariid genera by having cordons with a sinistral torsion. Parachordatortilis possesses cordons consisting of two rows of delicate cuticular plates delimiting a longitudinal canal. This pattern of cordon structure suggests that Parachordatortilis is closely related to Dispharynx Railliet, Henry & Sisoff, 1912, Synhimantus Railliet, Henry & Sisoff, 1912 and Chordatortilis Machado de Mendon?a & Olivera de Rodrigues, 1985. P. mathevossianae is redescribed on the basis of light and scanning electron microscopical observations of specimens collected from a common kestrel Falco tinnunculus L. in southern Italy.     

Restudy of the generitype of Aviculariella,a. alcyona Wehr, 1931 (Nematoda: Acuariidae)

Summary Aviculariella alcyona Wehr, 1931 is redescribed on the basis of specimens from the gizzard of Megaceryle a. alcyon (L.) (Alcedinidae). Numerous characters are reported for the first time. The genus is distinguished from Rusguniella and Ingliseria by the presence of triangular cordons with an inner denticulate border, a prominent cephalic vesicle behind the cordons and simple deirids. The genus also contains: A. brevis (Maplestone, 1931) of Halcyon smyrnensis in India; A. alcedonis (Yamaguti & Mitunaga, 1943) of Alcedo atthis bengalensis in Taiwan; A. collaricephala (Oschmarin, 1959) of Alcedo atthis in the U.S.S.R.; A petterae Bain & Chabaud, 1965 of Corythornis vingtsioides (Turdidae) in Madagascar and A. alii (Rasheed, 1960) n. comb. of Ceryle radis leucomelanura in India; the last-named species may be a synonym of A. brevis. The status of some of these species requires further study. ac]19790421     

The taxonomy of Tylenchorhynchinae (Nematoda: Tylenchida) with longitudinal lines and ridges

Summary The taxonomy of those Tylenchorynchinae which have longitudinal lines or ridges on the cuticle is discussed. Dolichorhynchus is restricted to species with four incisures in the lateral field, lateral vulval flaps and a terminally notched bursa. D. prophasmis n. sp. is described. Neodolichorhynchus n. g. is erected for those species previously in Dolichorhynchus which have no lateral vulval flaps and a normal bursa, including: N. microphasmis (Loof, 1959) n.comb., N. judithae (Andrássy, 1962) n.comb., N. sulcatus (de Guiran, 1967) n.comb., and N. gladiolatus (Fortuner & Amougou, 1973) n.comb. Tessellus n.g. is proposed for T. claytoni (Steiner, 1937) n.comb. and T. pachys (Thorne & Malek, 1968) n.comb. the only remaining Tylenchorhynchus species with longitudinal cuticular lines. They are characterized by a rounded non-offset lip region, four incisures in the lateral field and a cuticular annulation divided into prominent blocks by deep longitudinal cuticular lines.     

New species of Alaus Eschscholtz, 1829 (Coleoptera: Elateridae,Agrypninae, Hemirhipini)

Four new species of Alaus Eschscholtz, 1829 are described: A. cinnamomeus n. sp., A. latlpennls n. sp., A. serlceus n. sp. and A. thoracopunctatus n. sp. Three species removed from Chalcolepldlus Eschscholtz, 1829, are transferred to this genus: A. allcll (Pjatakowa, 1941) n. comb., A. haroldl (Candèze, 1878) n.comb. and A. unlcus (Fleutiaux, 1910) n. comb. The characters of external morphology of these seven species and male and female genitalia, when available, are described and illustrated. An identification key for all species of the genus is included: A. allcll (Pjatakowa, 1941) n. comb., A. calcarlpllosus Casari, 1996, A. cinnamomeus n. sp., A. haroldl (Candèze, 1878) n. comb., A. latlpennls n. sp., A. lusclosus (Hope, 1832), A. melanops Leconte, 1863, A. myops (Fabricius, 1801), A. nobllls Sallé, 1855, A. oculatus (Linnaeus, 1758), A. patrlclus (Candèze, 1857), A. plebejus Candèze, 1874, A. serlceus n. sp., A. thoracopunctatus n. sp., A. tricolor (Olivier, 1790), A. unlcus (Fleutiaux, 1910) n. comb., A. veracruzanus Casari, 1996 and A. zunianus Casey, 1893.     

The erection of Pelecanema n. g. (Nematoda: Spirurida: Acuariidae), with redescriptions of P. sirry (Khalil, 1931) n. comb. and P. pelecani (Johnston & Mawson, 1942) n. comb.

Pelecanema n. g. is erected for P. sirry (Khalil, 1931) n. comb., syn. Synhimantus sirry Khalil, 1931 (type-species) and P. pelecani (Johnston & Mawson, 1942) n. comb., syn. Dispharynx pelecani Johnston & Mawson, 1942. In the structure of its cordons, consisting of two rows of delicate cuticular plates, the new genus is similar to Synhimantus Railliet, Henry & Sisoff, 1912, Dispharynx Railliet, Henry & Sisoff, 1912, Chordatortilis Machado de Mendon?a & Olivera de Rodrigues, 1965 and Parachordatortilis Mutafchiev, Santoro & Georgiev, 2010. Pelecanema sirry, a parasite of Pelecanus onocrotalus L. and P. crispus Bruch (Pelecaniformes, Pelecanidae) in Africa (Egypt and Senegal) and Europe (Ukraine and Bulgaria), is redescribed using light and scanning electron microscopy on the basis of specimens from P. crispus from Bulgaria. Pelecanema pelecani, a parasite of Pelecanus conspicillatus Temminck in Australia, is also redescribed using light microscopy on the basis of specimens from its type-host and type-locality. In contrast to a previous opinion recognising Pelecanema sirry and P. pelecani as synonyms, the two species are considered distinct and P. pelecani is validated.     

Parapharyngodon osteopili n.sp. (Pharyngodonidae: Oxyuroidea) and a revision of Parapharyngodon and Thelandros

Summary Parapharyngodon osteopili n.sp. is described from the Cuban treefrog Osteopilus septentrionalis (Hylidae; Anura). Parapharyngodon Chatterji, 1933 and Thelandros Wedl, 1862 are redefined and distinguished on the basis of male and female caudal morphology and egg structure. Parapharyngodon spp. are found in insectivorous reptiles and amphibians whereas Thelandros spp. are essentially parasites of herbivorous and omnivorous reptiles. The following species are transferred to Parapharyngodon from Thelandros and represent new combinations: Parapharyngodon echinatus (Rudolphi, 1819), P. hemidactylus (Patwardhan, 1935), P. khartana (Johnston & Mawson, 1941), P. trachysauri (Johnston & Mawson, 1947), P. californiensis (read & Amrein, 1952), P. meridionalis (chabaud & Brygoo, 1962), P. mabouia (Rao & Hiregaudar, 1962), P. iguanae (Telford, 1965), P. calotis (Johnson, 1966), P. maculatus (Caballero, 1968) and P. garciae (Schmidt & Whittaker, 1975). Thelandros awokoyai (Babero & Okpala, 1962) n.comb., is transferred from Parapharyngodon. P. megaloon (Linstow, 1906) n.comb., P. seurati (Sandground, 1936) Freitas, 1957, P. waltoni (Read & Amrein, 1952) n.comb., P. cameroni (Belle, 1957) n.comb., P. aspiculus Khera, 1961, T. cinctus (Lonstow, 1897) and T. kuntzi Belle, 1957 are considered species inquirendae. ac]19810406     

Reclassification of Oxysomatium inglisi Anderson, 1964 and Aplectana gigantica olsen, 1938 (nematoda:Cosmocercoidea) from north American frogs

Summary Aplectana gigantica Olsen, 1938 and Oxysomatium inglisi Anderson, 1964 (Cosmocercidae) have been re-examined. Study of cephalic, oesophageal and male caudal structures and of the egg demonstrates that both species belong in the Kathlaniidae and they are reclassified as Falcaustra inglisi (Anderson, 1964) n. comb. and Megalobatrachonema gigantica (Olsen, 1938) n. comb. The genus Megalobatrachonema Yamaguti, 1941 is divided into M. (Megalobatrachonema) n. subg. (with M. nipponica Yamaguti, 1941 and M. gigantica) and M. (Chabaudgolvania) n. subg. (with M. campanae Chabaud & Golvan, 1959 and M. terdentatum (Linstow, 1898)). M. (Chabaudgolvania) lacks oesophageal valves which are present in M. (Megalobatrachonema). It is suggested that F. inglisi and M. gigantica illustrate a trend in the evolution of the Kathlaniinae towards reduction of cephalic support structures and simplification of the oesophagus to a club-shaped form lacking valves. An evolutionary hypothesis linking the Kathlaniinae to the Quimperiidae (Seuratoidea) is presented. The genus Chabaudinema Díaz-Ungría, 1968 is synonymized with Spectatus Travassos, 1923 and its type species is designated Spectatus americana (Díaz-Ungría, 1968) n. comb. ac]19791109     

Alesiella gen.n. and a newly discovered relict lineage of Staphylinini (Coleoptera: Staphylinidae)

This study aimed to identify the sister group of the poorly known and morphologically isolated Burmese species Quedius lineipennis within the tribe Staphylinini (Staphylinidae: Staphylininae) using morphological characters. Phylogenetic analysis of a broad taxon sample demonstrated that this Asian species is not a member of the genus Quedius but forms the sister taxon to the Neotropical genus Quediomacrus. Both taxa were shown to be members of a hitherto unrecognized lineage with a highly disjunct distribution. The lineage is hypothesized to be Asian in origin, with dispersals to the Americas during the early Eocene climatic maximum via Beringia and to Australia via land connections in the late Miocene. The current distribution of the lineage is considered to be relictual. New phylogenetic hypotheses within ‘Quediina’ and Staphylinini as a whole are proposed and the general tree topology of Staphylinini recovered by recent morphological studies is refined. Phylogenetic relationships within the Quedius complex remain unclear. Alesiella Brunke and Solodovnikov gen.n. , is erected for Quedius lineipennis and the Quedius subgenus Quedionuchus is reinstated to genus level with new combinations as follows: Quedionuchus atl (Smetana, 1975), comb.n. ; Quedionuchus calli (Smetana, 1976), comb.n. ; Quedionuchus cipactli (Smetana, 1976), comb.n. ; Quedionuchus coatl (Smetana, 1976), comb.n. ; Quedionuchus ehacatl (Smetana, 1976), comb.n. ; Quedionuchus ollin (Smetana, 1976), comb.n. ; Quedionuchus ozomatli (Smetana, 1975), comb.n. ; Quedionuchus reitterianus (Bernhauer, 1944), comb.n. ; Quedionuchus samuraicus (Bernhauer and Schubert, 1916), comb.n. ; Quedionuchus schultzei (Smetana, 1975), comb.n. ; Quedionuchus tecpatl (Smetana, 1976), comb.n. ; Quedionuchus xochitl (Smetana, 1976). Quedius lugubris Lokay, 1913 is transferred from the subgenus Quedionuchus to the subgenus Distichalius and placed in synonymy: Quedius punctatellus (Heer, 1839) = Quedius lugubris Lokay, 1913, syn.n .

A revision of the nematode genus Odontoterakis Skrjabin & Schikhobalova, 1947 (Heterakoidea)

Odontoterakis Skrjabin &; Schikhobalova, 1947 contains five species from South American and Australian birds: O. crypturi (Baylis, 1944), type-species; O. alata (Schneider, 1866) n. comb.; O. fariai (Travassos, 1913); O. valvata (Schneider, 1866); O. bancrofti (Johnston, 1912); all with slightly curved cordons, cheilorhabdions within mass of lips, and in most species a pair of elongate papillae between para-suctorials and peri-cloacals. Haroldakis n. g. from South American birds, contains Heterakis multidentata Baylis, 1944 as type- and sole species, with non-curved cordons, cheilorhabdions projecting beyond mass of lips, a pair of sessile papillae on raised area between para-suctorials and peri-cloacals, and a median doubled structure on a raised posterior cloacal lip. Synonyms recognised are: Heterakis arquata Schneider, 1866 = O. alata; H. arquata of Travassos (1913) nec Schneider, 1866 = (?) O. crypturi; H. brasiliana von Linstow, 1899 = species dubia; H. brasiliana of Travassos (1918) nec von Linstow = (?) O. alata; H. skrjabini Cram, 1927 = O. alata; Pseudostrongyluris Guerrero, 1971 = Strongyluris A. Müller, 1894; Strongyluris spiculatus Cobbold, 1861 = species dubia.     

Andracantha, a new genus of Acanthocephala (Polymorphidae) from fish-eating birds, with descriptions of three species.

Problems in taxonomy of the Polymorphidae are discussed, with particular reference to trunk spines. Andracantha gen. n. is proposed for species with genital spines and 2 fields of trunk spines. Corynosoma gravida Alegret 1941, C. mergi Lundstro?m 1941 and C. phalacrocoracis Yamaguti 1939 are redescribed and placed in Andracantha, with A. gravida (Alegret, 1941) comb. n. designated as type species.     

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.     

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. This published work has been registered in ZooBank, http://zoobank.org/urn:lsid:zoobank.org:pub:25B0C220‐DEE4‐4B0C‐88EA‐35FDE298EBC5 .     

Molecular phylogeny,larval case architecture,host–plant associations and classification of European Coleophoridae (Lepidoptera)

Bauer, F., Stübner, A., Neinhuis, C. & Nuss, M. (2012). Molecular phylogeny, larval case architecture, host–plant associations and classification of European Coleophoridae (Lepidoptera). —Zoologica Scripta, 41, 248–265. Several attempts based on adult morphology have aimed at classifying the megadiverse Coleophoridae, either by defining species groups or by splitting the large genus Coleophora into many smaller genera. A previous cladistic analysis focussing on larvae suggests monophyly of some case type groups as well as host–plant associations with a preference for certain plant tissues and growth forms. Here, a first molecular phylogeny for Coleophoridae is presented to test these partly contradicting hypotheses. Bayesian statistics is applied to different partitioning strategies of a COI + wingless data set (1815 bp) for 105 European species, revealing eight monophyletic species groups. A broader defined Coleophora with internal groups is better supported than the division into many genera. Goniodoma Zeller, 1849 syn. rev. and Metriotes Herrich‐Schäffer, 1853 syn. n. are nested within Coleophora Hübner, 1822. Seven species are transferred to Coleophora: C. auroguttella ( Zeller, 1849 ) comb. rev., C. limoniella Stainton, 1884 comb. rev., C. millierella (Ragonot, 1882) comb. n., C. nemesi (C?pu?e, 1970) comb. n., C. sinica (Li & Zheng, 2002) comb. n. (from Goniodoma) as well as C. jaeckhi (Baldizzone, 1985) comb. n. and C. lutarea (Haworth, 1828) comb. n. (from Metriotes). None of the formerly suggested case types is synapomorphic for any of the recovered clades. In contrast, cases built from glossy silk that turns black or dark brown is synapomorphic for the vibicella group. Some clades have radiated on certain plant taxa along with a specialisation in specific tissues, for example, the clade containing the saturatella (leaf miners) and frischella (seed miners) groups is associated with Fabaceae, the albella group (seed miners) with Caryophyllales and the serpylletorum group (leaf miners) with Lamiaceae. Calculating an index of host specificity for all studied species confirms significant differences between seed and leaf feeders on herbaceous plants, but not between leaf feeders on herbaceous and woody plants.     

Monogeneans from the gills of glassfishes (Teleostei: Perciformes: Ambassidae) in India, with the proposal of Chandacleidus n. g. (Monogenea: Dactylogyridae)

Chandacleidus n. g. (Monogenea, Dactylogyridae) is proposed to include three species collected from the gills of Indian glassfishes (Ambassidae): Chandacleidus recurvatus (Jain, 1961) n. comb. (syn. Urocleidus recurvatus Jain, 1961) from Chanda nama and C. ranga (new host record) is redescribed; and Chandacleidus saiensis n. sp. and C. lucknowensis n. sp., both from Chanda nama and C. baculis, are described. Chandacleidus n. g. is characterised by species possessing: posteriorly united intestinal caeca; overlapping gonads (testis dorsal to ovary); a counterclockwise male copulatory organ; a grooved accessory piece; a dextro-marginal vaginal pore; a haptor with two lateral flaps and armed with dissimilar dorsal and ventral anchor/bar complexes and 14 similar hooks (dissimilar in size); and hook shanks comprised of two subunits.     

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.     

Pararotylenchus n. gen. (Pararotylenchinae n. subfam., Hoplolaimidae) with Six New Species and Two New Combinations

A new subfamily, Pararotylenchinae, (Hoplolaimidae) is described. It includes a single genus, Pararotylenchus n. gen., six new species, attd two new combinations, Pararotylenchus (syn. Tylenchorhynchus) brevicaudatus (Hopper, 1959) n. comb. and Pararotylenchus (syn. Rotylenchus) pint (Mamiya, 1968) n. comb. Pararotylenchinae is similar to certain other Hoplolaimidae, such as Rotylenchinae, with respect to most characters including the short tail, the position of the phasmids near the anus, and the relatively great distance of the dorsal gland orifice from the base of the stylet knobs. The lip region, as observed with the scanning electron microscope, conforms to the basic pattern for Hoplolaimidae. The labial disc is round with slit-like amphidial openings at the lateral sides of the periphery of the disc. The distinctive anterior-most lip annule is segmented into six sectors. Unlike other Hoplolaimidae, however, the esophageal glands of Pararotylenchinae form a basal bulb similar to that of Tylenchorhynchidae; other characters do not resemble Tylencborhynchidae. Specimens of Pararotylenchus have been recovered only from cool regions at high elevations and Pacific coastal areas in the Western United States, Japan, and Korea.     

A critical review of Antarctic Conoidea (Neogastropoda)

ABSTRACT

The Antarctic Conoidean fauna is critically reviewed based on published data and specimens in the collections of the USNM, IORAS and MNHN. Forty-two species and subspecies of the superfamily Conoidea are recorded as occurring within the Antarctic Convergence (excluding the fauna of the Kerguelen Islands) and are attributed to 14 genera and seven families. These include the new taxa: Antarctospira n. gen. (type species—Leucosyrinx badenpowelli Dell, 1990); Drilliola antarctica n. sp.; Pleurotomella (Pleutoromella) tippetti n. sp.; Pleurotomella (Anomalotomella) petiti n. sp.; Xanthodaphne pastorinoi n. sp. Aforia watsoni is introduced as a new name for Pleurotoma (Surcula) lepta Watson, 1881, non Pleurotoma lepta Edwards, 1861. A lectotype is designated for Conorbella antarctica (Strebel, 1908). New combinations are also proposed. Antarctospira badenpowelli (Dell, 1990), n. comb. (previously assigned to Leucosyrinx); Antarctospira principalis (Thiele, 1912), n. comb. (previously assigned to Typhlomangelia); Antarctospira mawsoni (Powell, 1958), n. comb. (previously assigned to Leucosyrinx); Typhlodaphne paratenoceras (Powell, 1951), n. comb. (previously assigned to Leucosyrinx); Belalora weirichi (Engl, 2008), n. comb. (previously assigned to Oenopota); Pleurotomella (Anomalotomella) innocentia (Dell, 1990), n. comb. (previously assigned to Typhlodaphne); Pleurotomella (Anomalotomella) nipri (Numanami, 1996), n. comb. (previously assigned to Typhlodaphne); Xanthodaphne raineri (Engl, 2008), n. comb. (previously assigned to Pleurotomella); Aforia hedleyi (Dell, 1990), n. comb. (previously assigned to Pontiothauma). The majority of Antarctic conoidean taxa have hypodermic marginal teeth. Although there is a similar relative abundance of conoideans in Antarctic waters to that seen in other well-studied faunas, the low number of conoideans is indicative of the general impoverishment of the gastropod fauna in the region. Fourteen percent (2 of 14) of conoidean genera that occur within the Antarctic Convergence are endemic to Antarctic waters, as are 82% (34 of 42) of the species. Most taxa have very broad bathymetric ranges, some extending from bathyal to hadal depths. The greatest species diversity was at bathyal depths.     

Trioza hopeae sp. nov. (Hemiptera: Triozidae): A pest on Hopea odorata (Malvales: Dipterocarpaceae) in Vietnam

Trioza hopeae sp. nov. is described and illustrated from Vietnam. Trioza hopeae develops on Hopea odorata, a valuable timber tree on which it causes serious damage by inducing leaf galls. The new species is closely related to Trioza minuta (Mathur) comb. nov. (from Ceropsylla Riley), an Indian species associated with Shorea robusta. Differences between the two species are discussed. Another five Indian species are transferred here from Ceropsylla to Trioza Foerster as T. ferruginea ( Mathur, 1975 ) comb. nov., T. fulvida ( Mathur, 1975 ) comb. nov., T. indica ( Kandasamy, 1986 ) comb. nov., T. longivenata ( Kandasamy, 1986 ) comb. nov., and T. parvus ( Kandasamy, 1986 ) comb. nov.     

Suttonema delta n. g., n. sp. (Nematoda: Trichostrongylina: Heligmosomoidea) from Oxymycterus rufus (Rodentia: Sigmodontinae) in Argentina

A new nippostrongyline, Suttonema delta n. g., n. sp., is described from the intestine of Oxymycterus rufus (Rodentia: Sigmodontinae) from Argentina, in a host from which trichostrongylid nematodes were hitherto unknown. The new genus is very similar to Stilestrongylus Freitas, Lent & Almeida, 1937 and Malvinema Digiani, Sutton & Durette-Desset, 2003, both parasites of Neotropical sigmodontines, in the features of the caudal bursa (with a pattern of type 1-4, asymmetrical with hypertophied right lobe) and the presence of cephalic structures resembling cuticular cordons. The larval synlophe is also identical to that of Stilestrongylus freitasi Durette-Desset, 1968. The new genus is differentiated by an adult synlophe with few ridges (9-12 at mid-body) of two different types: small, rounded ridges without cuticular support on the dorsal side, and pointed ridges of unequal size on the ventral side and in lateral fields. It is also characterised by the presence of comaretes on the left ventral and ventral fields of the synlophe.     

Phylogeny of Paussus L. (Carabidae: Paussinae): unravelling morphological convergence associated with myrmecophilous life histories

Ant nest beetles (Paussus L.) are ecologically fascinating and phenotypically bizarre. Obligate myrmecophiles, Paussus have undergone extreme adaptations for life with ants and their profound range of phenotypic diversity has been difficult to reconcile in a systematic framework. We conducted a detailed morphological study of Paussus utilizing novel techniques and character systems in order to discover anatomical apomorphies diagnostic of the major clades of Paussus strongly supported by molecular data. Bayesian inference (BI) of molecules alone, morphology alone and varying combinations of the two data types reveal that morphology is informative for placing Paussus species, despite the extreme phenotypic diversity and convergence prevalent in the group. We propose a new classification for Paussus based on this phylogeny. The genus Paussus is revised to include all genera, subgenera and species formerly classified as Paussus by Nagel (2003) in addition to Hylopaussus syn.n. , Hylotorus syn.n. and Granulopaussus syn.n. The following species are transferred to Paussus: Paussus sebakuanus (Péringuey) comb.n. , Paussus gracilis (Reichensperger) comb.n. , Paussus bucephalus Gyllenhal, Paussus caroli (Reichensperger) comb.n. , Paussus uelensis (Reichensperger) comb.n. , Paussus hottentottus (Westwood) comb.n. , Paussus blanchardi (Raffray) comb.n. , Paussus basilewskyi (Luna de Carvalho) comb.n. , Paussus granulatus Westwood, Paussus sankuruensis Reichensperger, Paussus leleupi (Reichensperger) comb.n. , Paussus reichenspergeri (Luna de Carvalho) comb.n. We formally delineate and diagnose the following major subgroups of Paussus: Paussus I series, comprising the subgenera Bohemanipaussus Luna de Carvalho stat. rev. sensu n. , Bathypaussus Wasmann stat. rev. sensu n. , and Edaphopaussus Kolbe stat. rev. sensu n. ; the Paussus II series comprising the subgenera Paussus L. stat. rev. sensu n. , Klugipaussus Kolbe stat. rev. sensu n. , Scaphipaussus Fowler stat. rev. sensu n. , Hylotorus Dalman stat.n. sensu n. , and Anapaussus Wasmann stat. rev. sensu n. ; and the Paussus III series comprising the subgenera Lineatopaussus Kolbe stat. rev. sensu n. and Shuckardipaussus Kolbe stat. rev. sensu n.
