New fossils from China elucidating the phylogeny of Praesiricidae (Insecta: Hymenoptera)

A new subfamily of Praesiricidae (Pamphilioidea), Decorisiricinae subfam.n. , is erected based on three new genera: Decorisiricius gen.n. , Limbisiricius gen.n. and Brevisiricius gen.n. Two new species – Decorisiricius patulus gen. et sp.n. and D. longus sp.n. – from the Lower Cretaceous Yixian Formation and three species –Limbisiricius aequalis gen. et sp.n. , Limbisiricius complanatus sp.n. and Brevisiricius partialis gen. et sp.n. – from the Middle Jurassic Jiulongshan Formation, are described. Based on these well‐preserved new fossil specimens and previously published data, the nonmonophyly of Praesiricidae is confirmed and the phylogenetic relationships of species of Praesiricidae are analysed for the first time. Two main clades within Praesiricidae are recognized from the cladistic analysis: Decorisiricinae subfam.n. forms a monophyletic lineage, with the remaining members of Praesiricidae plus Megalodontes (Megalodontesidae) forming its sister group. The two subfamilies Archoxyelydinae and Praesiricinae are discarded with no strong supported synapomorphic characters based on phylogenetic research. A key to all genera of Praesiricidae is provided. This published work has been registered in ZooBank, http://zoobank.org/urn:lsid:zoobank.org:pub:38D703ED‐127A‐4DB0‐8153‐8D78AF4AC212 .     

Cladispa Baly: revision,biology and reassignment of the genus to the tribe Spilophorini (Coleoptera: Chrysomelidae: Cassidinae)

The genus, Cladispa Baly 1858, is transferred from the tribe Imatidiini (= Cephaloleiini Chapuis, 1875) to Spilophorini Chapuis, 1875 based on the review of type material, newly collected specimens and molecular phylogenetic analysis. The type species, C. quadrimaculata Baly, 1858, is redescribed, and two new species, C. amboroensis sp.n. from Bolivia (Santa Cruz Department) and C. ecuadorica sp.n. from Ecuador (Pastaza Province), are described and figured. The morphology of C. amboroensis sp.n. immature stages is broadly consistent with other Spilophorini. Field observations document that both C. quadrimaculata and C. amboroensis sp.n. are trophic specialists on Orchideaceae. Keys to Cladispa species and Spilophorini genera are provided. Trophic associations of other Cassidinae and Orchideaceae are discussed.

Systematics of the mealybug tribe Xenococcini (Hemiptera: Coccoidea: Pseudococcidae), with a discussion of trophobiotic associations with Acropyga Roger ants

The mealybug tribe Xenococcini (Hemiptera: Pseudococcidae) comprises three genera, Eumyrmococcus Silvestri, Neochavesia Williams & Granara de Willink and Xenococcus Silvestri, trophobiotically associated with ants of the genus Acropyga Roger (Hymenoptera: Formicidae). Alate Acropyga queens vertically transmit trophobionts by carrying them along on the nuptial flight, a unique behaviour termed trophophoresy. Xenococcine mealybugs have never been collected without ant associates, and putatively only associate with Acropyga. Xenococcine mealybugs are characterized by the absence of dorsal ostioles, presence of distally cup‐shaped circuli and a female pupal instar rather than a third feeding instar. The phylogeny of this tribe is derived for the first time using morphological data from adult females (53 characters) through Bayesian inference and maximum parsimony methods. Monophyly of the clade is strongly supported and a discussion of their taxonomy is included. The Neotropical genus Neochavesia was recovered as monophyletic. Eumyrmococcus, as previously defined, was recovered as paraphyletic, and thus two species are transferred to Xenococcus: Xenococcus kinomurai (Williams & Terayama) comb.n. and Xenococcus neoguineensis (Williams) comb.n . Two species groups are recognized within Eumyrmococcus: the Eumyrmococcus scorpioides species group, restricted to the eastern Mediterranean and Afrotropics, and the Eumyrmococcus smithii species group, restricted to the Orient and Indo‐Australasia. Six new species are described: Eumyrmococcus adornocapillus sp.n. from Australia; Eumyrmococcus sarnati sp.n. from Fiji; Eumyrmococcus ordinotersus sp.n. and Xenococcus baryglobosus sp.n. from the Solomon Islands; Neochavesia cephalonodus sp.n. from French Guiana; and Neochavesia linealuma sp.n. from Guyana. The systematics and biology of the xenococcine mealybugs is discussed in the context of obligate ant symbiosis.     

The subfamily classification of the Micropezidae and the genera of Eurybatinae (Diptera: Schizophora)

The classification of the family Micropezidae is re-examined and a key is given to the five subfamilies now recognised, of which Calycopteryginae is described as new and Eurybatinae is raised from tribal rank. Metopochetini is a new tribe of Eurybatinae. A key is given to the nine genera now included in the Eurybatinae, of which Papeza is described as new. P.szentivanyi is a new species from Papua. Notes on the taxonomy and distribution of genera are included. The position of Anaeropsis Bigot in the Micropezidae is confirmed. New synonymies are established as follows: Crepidochetus Enderlein (= Gongylocephala Czerny syn. n.); Metopochetus bivittatus (Macquart) (= Calobata tenuipes Walker syn. n.). New generic combinations are as follows: Metopochetus terminalis (Walker) and M.compressus (Walker) from Calobata; Crepidochetus nigrifemur (Czerny), C.pallidus (Steyskal), and Cater (Steyskal) from Gongylocephala; Crosa fragilis (Walker) from Micropeza; Crosa nigriventris (Enderlein) and C.uneifera (de Meijere) from Eurybata.     

Two new species of Haemaphysalis Koch, 1844 (Acari: Ixodidae) in the H. (Rhipistoma) spinulosa subgroup,parasites of carnivores and hedgehogs in Africa

Haemaphysalis (Rhipistoma) princeps n. sp. (Acari: Ixodidae) and H. (R.) camicasi n. sp. are described based on adults. Adults of H. princeps n. sp. were mostly collected from various carnivores (Carnivora: Canidae, Felidae, Herpestidae, Mustelidae, Viverridae) and hedgehogs (Erinaceomorpha: Erinaceidae); few specimens were found on hare (Lagomorpha: Leporidae), various rodents (Rodentia: Muridae) and an antelope (Artiodactyla: Bovidae) in Benin, Burkina Faso, Cameroon, Chad, Côte d’Ivoire, Ghana, Mali, Nigeria, Senegal, South Sudan and Sudan. Few adults of H. princeps n. sp. were reared from nymphs collected on rodents (Rodentia: Muridae) and shrew (Soricomorpha: Soricidae). Adults of H. camicasi n. sp. were also mostly collected from various carnivores (Carnivora: Canidae, Felidae, Herpestidae, Mustelidae, Viverridae) and hedgehogs (Erinaceomorpha: Erinaceidae); few specimens were found on different rodents (Rodentia: Muridae, Nesomyidae, Sciuridae), hare (Lagomorpha: Leporidae) and bushbaby (Primates: Galagidae) in Benin, Burkina Faso, Cameroon, Central African Republic, Chad, Côte d’Ivoire, Nigeria, Senegal, South Sudan and Togo. Males and females of both species can be differentiated from each other and other H. spinulosa-like ticks by their size, pattern of punctations on conscutum/scutum, size of setae, shape of genital structures, size and shape of spiracular plates, dorsal cornua, posterodorsal and posteroventral spurs on palpal segments II and spur on coxae.

     

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.     

Fern sporophagy in Coleoptera from the Juan Fernandez Islands,Chile, with descriptions of two new genera in Cryptophagidae and Mycetophagidae

Abstract. Fern sporophagy is reported in species of Cryptophagidae, Mycetophagidae and Anthribidae occurring on the Juan Fernandez Islands, Chile. The following taxa are described and/or discussed: Cryptophagidae: Cryptothelypterus gen.n., with five species: C.obrieni sp.n., C.pteropilosus sp.n., C.selkirki (Bruce) comb.n., C.skottsbergi (Bruce) comb.n., and C.splendens (Bruce) comb.n.; Mycetophagidae: Filicivora gen.n., with one species, F.chilensis (Philippi & Philippi) comb.n.; and Anthribidae: Opisolia lenis Jordan. A key to the species of Cryptothelypterus is provided. Convergent adaptations for fern sporophagy in these groups are discussed, hypotheses are given for the evolution of this habit, and comments are made on wing atrophy.     

Redefining the damselfly families: a comprehensive molecular phylogeny of Zygoptera (Odonata)

An extensive molecular phylogenetic reconstruction of the suborder Zygoptera of the Odonata is presented, based on mitochondrial (16S, COI) and nuclear (28S) data of 59% of the 310 genera recognized and all (suspected) families except the monotypic Hemiphlebiidae. A partial reclassification is proposed, incorporating morphological characters. Many traditional families are recovered as monophyletic, but reorganization of the superfamily Coenagrionoidea into three families is proposed: Isostictidae, Platycnemididae and Coenagrionidae. Archboldargia Lieftinck, Hylaeargia Lieftinck, Palaiargia Förster, Papuargia Lieftinck and Onychargia Selys are transferred from Coenagrionidae to Platycnemididae, and Leptocnemis Selys, Oreocnemis Pinhey and Thaumatagrion Lieftinck from Platycnemididae to Coenagrionidae. Each geographically well‐defined clade of Platycnemididae is recognized as a subfamily, and thus Disparoneurinae (i.e. Old World ‘Protoneuridae’) is incorporated, Calicnemiinae is restricted, and Allocnemidinae (type genus: Allocnemis Selys) subfam.n ., Idiocnemidinae (type genus: Idiocnemis Selys) subfam.n . and Onychargiinae (type genus: Onychargia Selys) subfam.n . and Coperini trib.n . (type genus: Copera Kirby) are described. Half of Coenagrionidae belongs to a well‐supported clade incorporating Coenagrion Kirby and the potential subfamilies Agriocnemidinae, Ischnurinae and Pseudagrioninae. The remainder is less well defined, but includes the Pseudostigmatidae and New World Protoneuridae that, with Argiinae and Teinobasinae, may prove valid subfamilies with further evidence. Ninety‐two per cent of the genera formerly included in the polyphyletic Amphipterygidae and Megapodagrionidae were studied. Pentaphlebiidae, Rimanellidae and Devadattidae fam.n . (type genus: Devadatta Kirby) are separated from Amphipterygidae, and Argiolestidae, Heteragrionidae, Hypolestidae, Philogeniidae, Philosinidae and Thaumatoneuridae from Megapodagrionidae. Eight further groups formerly placed in the latter are identified, but are retained as incertae sedis; the validity of Lestoideidae, Philogangidae and Pseudolestidae is confirmed. For some families (e.g. Calopterygidae, Chlorocyphidae) a further subdivision is possible; Protostictinae subfam.n . (type genus: Protosticta Selys) is introduced in Platystictidae. Numerous new combinations are proposed in the Supporting Information. Many long‐established families lack strong morphological apomorphies. In particular, venation is incongruent with molecular results, stressing the need to review fossil Odonata taxonomy: once defined by the reduction of the anal vein, Protoneuridae dissolves completely into six clades from five families.     

Six new species of the genus Diplopeltula (Nematoda: Diplopeltidae) with remarks on the heterogeneity of the taxon

Six new Diplopeltula species are described: D. pulchra sp.n., D. belgica sp.n., D. striolata sp.n. and D. curta sp.n. (Southern Bight of the North Sea), D. nellyae sp.n. and S. pumila sp.n. (New Caledonia). Diplopeltula indica Gerlach, 1962 is redescribed from Guadeloupe (FWI). Based on the examination of these seven Diplopeltula species, the genus has been reappraised. The systematic position of the other genera of the Diplopeltidae Filipjev, 1918 is also discussed. Diplopeltoides Gerlach, 1962 is moved from the Aegialoalaimidae Lorenzen, 1981 to the Diplopeltidae.     

A new genus of the tribe Acratini from the continental Neotropical region (Coleoptera: Curculionoidea,Brentidae)

A group of 10 species belonging to the Neotropical tribe Acratini Alonso-Zarazaga, Lyal, Bartolozzi & Sforzi 1999, is shown to be monophyletic by a phylogenetic analysis based on 48 morphological characters. A new genus, Pertusius n. gen., is described, based on three derived characters of external and genital morphology: venter of prorostrum of males with fine median longitudinal carina, base of elytra with deep pit at the place of insertion on mesonotum, and proximal sclerite of endophallus more or less horseshoe-shaped. Eight species were previously known and, according to former authors, belonged to the genera Acratus Lacordaire 1865 [Pertusius apicalis (Sharp 1895), n. comb., P. errabundus (Kleine 1927), n. comb., P. extrarius (Kleine 1927), n. comb., P. fidus (Kleine 1927), n. comb. and P. telesi (Soares & Meyer 1959), n. comb.] and Proteramocerus Kleine 1921 [Pertusius chalcites (Perty 1832), n. comb., P. filum (Sharp 1895), n. comb., and P. laevis (Germar 1824), n. comb.]. Four new synonymies are proposed: Proteramocerus disparilis Soares & Dias 1971, n. syn. for Acratus apicalis Sharp 1895; Teramocerus laevigatus Boheman 1840, n. syn. for Arrhenodes chalcites Perty 1832; Acratus extraordinarius Kleine 1927, n. syn. for Acratus errabundus Kleine 1927; Proteramocerus diringshofeni Soares & Dias 1971, n. syn. for Acratus filum Sharp 1895. Two new species are described: Pertusius guyanensis n. sp. from French Guiana, and P. mexicanus n. sp. from Mexico (Yucatán Peninsula). Pertusius apicalis is newly cited from Bolivia and Peru, P. chalcites from Argentina and Paraguay, P. extrarius from Ecuador, P. fidus from Peru and P. telesi from Trinidad and Tobago and Venezuela. An identification key to species of the genus is provided.     

New species and new data on Protrinemuridae and Nicoletiidae (Zygentoma) from Eastern Asia and Pacific islands

Four new genera and eleven new species of Zygentoma thysanurans (families Protrinemuridae and Nicoletiidae) are described and some faunistic novelties reported from Oriental and Australian Regions, viz.: Protrinemura leclerci n. sp., from northern Thailand, Protrinemurella allacrotelsoides n. gen. n. sp., from southern Thailand, and Protrinemuroides celebensis n. gen. n. sp., from the Celebes islands (Protrinemuridae), Lepidospora (L.) digitata n. sp., from northern Thailand, L. (L.) deharvengi n. sp., from the Celebes, and Pseudobrinckina anempodiata n. gen. n. sp., from northern Thailand (Nicoletiidae: Coletiniinae), Gastrotheus (G.) papuanus n. sp., from Papua-New Guinea (Nicoletiidae: Atelurinae), and Metrinura celebensis n. sp., from the Celebes, Trinemurodes anomalocoxa n. sp., from southern Thailand, T. bedosae n. sp., from northern Thailand, and Allotrinemurodes thai n.gen. n. sp., from northern Thailand (Nicoletiidae: Subnicoletiinae). Bharatatelura malabarica Mendes is reported for the first time off the Indian sub-continent (in Suva). Proatelura jacobsoni Silvestri is recorded in Macao (southern China) and in the Moluccas islands and notes are presented on its male sex. Gastrotheus (Lasiotheus) nanus (Escherich) is found for the very first time in Macao, in Cook islands and in Niue. Identification keys are provided to Protrinemuridae genera and to species of Trinemurodes, and modifications are suggested to previously presented keys to Nicoletiidae genera and to Lepidospora and Metrinura species.     

Contribution to the blackfly fauna (Diptera: Simuliidae) of Iran

A collection of blackflies (Diptera: Simuliidae) from western Iran was examined, four species were recorded. Three new species are described: Tetisimulium iranicum sp. n., Wilhelmia lurestanica sp. n., and Crosskeyellum zagros sp. n. The presence of Tetisimulium coarctatum (Rubzov, 1940) in Iran is confirmed.     

Multivariate discrimination among cryptic species of the mite genus Chaetodactylus (Acari: Chaetodactylidae) associated with bees of the genus Lithurgus (Hymenoptera: Megachilidae) in North America

Twenty-seven morphological characters from 111 heteromorphic deutonymphs of the mite genus Chaetodactylus Rondani (Acari: Chaetodactylidae) were analyzed. The mites were collected from four species of bees of the genus Lithurgus Berthold (Hymenoptera: Megachilidae) in continental North America. Principal component and canonical variates analyses on Darroch and Mosimann shape and size-and-shape variables revealed the presence of three cryptic species. Chaetodactylus gibbosi sp. n. (Florida) is geographically isolated from C. lithurgi sp. n. distributed in Texas, New Mexico, Arizona, Colorado, and Idaho. Sympatric C. lithurgi and C. abditus sp. n. (USA: Arizona, Mexico: Socorro Is.) are seasonally isolated in Arizona. Chaetodactylus gibbosi is associated with a single bee species, Lithurgus gibbosus Smith in Florida. The host range of C. lithurgi includes bees flying predominantly in the spring: L. apicalis Cresson, L. littoralis Cockerell, and western L. gibbosus. Chaetodactylus abditus sp. n. is associated with L. planifrons Friese and L. echinocacti Cockerell, flying predominantly in the fall in Arizona. No distinct groups separated by geographic locality or size were detected in any species. A six-variable model developed by the canonical variates analysis and estimated using jackknife resampling and external validation (n=100) is capable of classifying the three species with 100% accuracy. Factors that influenced speciation of cryptic species of Chaetodactylus associated with Lithurgus are discussed. Based on morphological and geographical data and data on mite associates, the western and eastern populations of the bee L. gibbosus are distinct. Therefore, the taxonomic status of L. gibbosus s. lat. should be reevaluated.     

Generic revision of Cypricercinae McKenzie, 1971 (Crustacea,Ostracoda), with the description of three new genera and one new species and a phylogenetic analysis of the subfamily

The Cypricercinae are one of the most speciose subfamilies of non-marine ostracods, with more than 170 described species, mostly from the tropics. Although the identity of the subfamily as such is clear, because of the presence of unifying characters such as the Triebel’s loop in the attachment of the caudal ramus, the supra-specific taxonomy of this group has long been confused because of lack of good generic and tribal characters. Here, the generic characters of the Cypricercinae are revised. Eleven genera are retained in this subfamily, including three new genera: Bradleytriebella n. gen., Nealecypris n. gen. and Pseudostrandesia n. gen. Tanycypris siamensis n. sp. is described from Thailand. In addition, five species [Bradleystrandesia fuscata (Jurine, 1820), Bradleytriebella tuberculata (Hartmann, 1964), Nealecypris obtusa (Klie, 1933), Pseudostrandesia striatoreticulata (Klie, 1932), Spirocypris horrida (Sars, 1926)] are redescribed. A key to the genera is given. We propose three tribes: the nominal tribe Cypricercini McKenzie, 1971, as well as two new tribes, Bradleystrandesiini n. trib. and Nealecypridini n. trib. To evaluate the systematic relationships within this subfamily, phylogenetic analyses, based on morphological characters of valves and soft parts, were conducted. The Neighbour Joining (NJ) tree strongly supports the classification into three independent tribes, whereas the Maximum Parsimony (MP) tree shows that Bradleystrandesiini n. trib is actually a subgroup of the Cypricercini.

Ciliate Protozoa in the Rumen of Brazilian Water Buffalo,Bubalus bubalis Linnaeus*

SYNOPSIS Total numbers and distribution of genera, subgenera and species were determined for the ciliate protozoa in rumen contents of 4 Brazilian water buffalo Bubalus bubalis Linnaeus. The fauna of one animal, housed in close proximity to European and zebu-type cattle, differed considerably from that of the remaining animals, which were somewhat isolated on a large ranch. Several of the protozoan species observed in the semi-isolated animals were first described in rumen contents from humped Indian cattle, and their subsequent occurrence in other hosts and geographic locations has been limited or absent. In all, 49 different species of protozoa were found, 8 of which have not been previously described. Three of the new species belong to the genus Entodinium: E. ciculum sp. n., E. spinonucleatum sp. n. and E. triangulum sp. n.: 4 to Diplodinium (Ostracodinium): D. (O.) brazili sp. n., D. (O.) esalqum sp. n., D. (O.) nucleolobum sp. n., and D. (O.) tiete sp. n.; and one to Diplodinium (Eudiplodinium): D. (E.) bubalus sp. n.
