Two new genera of Bryozoa (Calloporidae) from New Zealand

Two new genera of the bryozoan family Calloporidae are described from New Zealand. The first, Leptinatella, is introduced for L. gordoni n. sp., specimens of which have been referred in the past to Watersia militaris (Waters) but are distinct from this species, which is a phase of the cribrimorph Corbulipora tubulifera (Hincks). The second genus, Bryocalyx, is introduced for B. cinnameus n. sp., which has small, conical colonies anchored by rhizoids. Another species of Bryocalyx is known from a few fragments only: and has also been referred in the past to Watersia sp. It is briefly discussed, but left unnamed here.     

A revision of the genus Metallolophia Warren (Lepidoptera,Geometridae, Geometrinae)

The Geometrine genus Metallolophia is revised. In addition to the 11 species known, five new species are described as new. All the known species are redescribed and lectotypes are designated for M. opalina (Warren), M. arenaria (Leech) and M. danielaria (Oberthür) (=M. arenaria (Leech)). The male of M. ocellata (Warren) and the females of M. medullosa Inoue and M. devecisi Herbulot are described for the first time. The generic characters based on all species are summarized and a key to all taxa is given. Illustrations of moths and genitalia are presented. The new and revised taxa are: Metallolophia purpurivenata sp. nov., Metallolophia cuneataria sp. nov., Metallolophia inanularia sp. nov., Metallolophia flavomaculata sp. nov., Metallolophia stueningi sp. nov. and Metallolophia ostrumaria Xue, syn. nov. (of Metallolophia albescens Inoue).     

Oribatid mites of Liebstadia (Acari: Oribatida: Scheloribatidae) from Mongolia,with notes on taxonomy of the genus

Three new species of oribatid mites belonging to the genus Liebstadia are described from Mongolia. The new species are characterized by the poorly developed pteromorphae; the club-shaped head of the sensilli; the absence of the dorsosejugal suture; the dorso-ventral thickness, and the length and arrangement of notogastral setae. In addition, L. similis (Michael, 1888) is redescribed and recorded for the first time in Mongolia. Protoribates serratomarginatus Mahunka, 1983 is synonymized with L. similis. A key to the known species of the genus Liebstadia is given.     

The pygmaeus-group of Euops Schoenherr (Coleoptera,Curculionoidea, Attelabidae), weevils associated with Nothofagus in New Guinea

A new species group of Euops Schoenherr from the highlands of New Guinea is described and referred to as the ‘pygmaeus-group’. It is comprised of 14 species which, except for E. singularis VOSS, are described as new: E. anggiensis sp. n., E. bicolor sp. n., E. convexus sp. n., E. fraterculus sp. n., E. ibelensis sp. n., E. kurulu sp. n., E. nothofagi sp. n., E. parvus sp. n., E. paraconvexus sp. n., E. platyrostris sp. n., E. porulosus sp. n., E. pygmaeus sp. n., and E. sedlaceki sp. n.. Most of the species are of relatively small body size. They form a monophyletic group characterized by the synapomorphic loss of the ventral suture between the galea and palpifer of the maxilla. Two other groups are recognized, the eucalypti-group and the quadrifasciculatus-group. They are believed to be closely related to the pygmaeus-group and all three species groups together are referred to as the ‘pygmaeus-complex’. A cladistic analysis of the pygmaeus-group is performed. All species with host records are reported to feed on the fresh leaf flush of Nothofagus. This is the first record of a group of leaf-chewing arthropods restricted to the subgenus Brassospora of Nothofagus.     

A review of the north-western Pacific species of the genus Paguristes (Decapoda: Anomura: Diogenidae), I. Five species initially reported by Ortmann (1892) from Japan

Five species of the hermit crab genus Paguristes Dana, 1851, initially reported by Ortmann (1892) from Japan, are revised based on the materials reported by Ortmann (1892), Doflein (1902), Balss (1913) and Miyake (1978), and on newly collected specimens. The specific status of P. palythophilus Ortmann, 1892, is clarified, and a species confused with P. palythophilus is described as new, P. albimaculatus. It has been revealed that P. kagoshimensis Ortmann, 1892, is actually a junior subjective synonym of P. digitalis Stimpson, 1858. The species heretofore assigned to P. kagoshimensis is described as new, P. versus. It has been confirmed that Paguristes acanthomerus Ortmann, 1892, is a valid species and that P. barbatus sensu Ortmann, 1892, is the same species as P. ortmanni Miyake, 1978. Further, a new species, P. doederleini, is described for P. setosus sensu Ortmann, 1892. It is also shown that a part of the group of specimens identified as Paguristes puniceus by Miyake (1978) is referable to P. doederleini. In addition to the three new species recognized herein, the four previously described species are also redescribed in detail in order to make clear their taxonomic status.     

A review of Eunotinae (Hymenoptera: Chalcidoidea: Pteromalidae) from China

Five genera of Eunotinae are included in this paper. Ophelosia, Moranila, Cephaleta, Eunotus are reviewed and a new genus Cavitas is described. Four new species, Cavitas concava sp. nov., Eunotus applanatus sp. nov., E. strenus sp. nov. and E. aequalivenus sp. nov. are described. The type specimens are deposited in the Zoological Museum, Institute of Zoology, the Chinese Academy of Sciences.     

Scale insects of the families Asterolecaniidae and Eriococcidae (Hemiptera: Coccoidea) in New Caledonia

The scale insect families Asterolecaniidae and Eriococcidae are discussed from New Caledonia. One new genus Oacoccus gen. nov., and a new species Oacoccus nothofagi sp. nov. on Nothofagus sp., are described in the Asterolecaniidae, and a new species Eriococcus millei sp. nov. is described in the Eriococcidae. A new genus Rhopalotococcus gen. nov., and two new species Rhopalotococcus dugdalei sp. nov. and Rhopalotococcus metrosideri sp. nov., are also described in the Eriococcidae. Both species induce leaf galls on Metrosideros sp. Keys are provided for all the New Caledonian genera and species in the families Asterolecaniidae and Eriococcidae.     

Recent and fossil species of Characodoma Maplestone, 1900 (Bryozoa) from the Mediterranean with description of two new species

Three species of Characodoma Maplestone, 1990 from the Mediterranean are discussed here. Two, C. rostratum and C. reclinatum are described as new from Pleistocene bathyal sediments of Southern Italy. The third, C. mamillatum (Seguenza, 1880) was already known from Tertiary-to-Quaternary sediments of Southern Italy. It has been recognized as the senior synonym of C. bifurcatum (Waters, 1918). Stratigraphical, geographical and ecological distributions of all the species are discussed. Morphological studies, principally of C. mamillatum, provide useful information about the life habit of these species.     

Two new phoxocephalids (Crustacea: Amphipoda: Phoxocephalidae) from the south-west Atlantic

A new genus and species, Parafoxiphalus longicarpus, and a new species, Metharpinia protuberantis belonging to the family Phoxocephalidae, are described from the Argentine Sea. Both taxa were collected from sandy substrata in the intertidal and subtidal regions. Parafoxiphalus longicarpus is related to Foxiphalus Barnard, 1979 and they share many characters, most of them in plesiomorphic condition. Metharpinia protuberantis is an intermediate species between Metharpinia Schellenberg, 1931 and Microphoxus Barnard, 1960, and its assignation to the first genus is discussed.     

The colonial ascidian fauna of Fiordland,New Zealand,with a description of two new species

A total of 17 species from the families Styelidae, Polyclinidae, Polycitoridae, Pseudodistomidae, Ritterellidae and Didemnidae are described for the first time in collections from remote fiords with steep-sided walls, high rainfall and high tidal flow on the south-west coast of New Zealand. The Fiordland ascidian assemblages are composed of endemic species, species with trans-Tasman affinities, species found in southern New Zealand and species found New Zealand wide, some of which have global distributions. Two Australian native species, Diplosoma velatum Kott, 2001 and Didemnum jucundum Kott, 2001 from South Australia are new records to New Zealand and a further eight species remain undescribed. Two new colonial ascidians Aplidium coronum sp. nov. and Trididemnum shawi sp. nov. are described in this paper.

On a new genus and new species of xanthid crab (Crustacea,Decapoda, Brachyura,Xanthinae) from the South China Sea,with notes on the genus Liagore De Haan, 1833

A new genus and new species of xanthid crab, Ovatis simplex, is described from the South China Sea. The genus is closest to Liagore but can be distinguished by a suite of carapace and male gonopod characters. The systematic position of Liagore is also considered, and both genera, Liagore and Ovatis, are here referred to the subfamily Xanthinae. Comparisons with the allied genera, Paratergatis and Pulcratis, are also provided.     

New species of the genus Troglocheles (Acari: Prostigmata: Rhagidiidae) from Oetztal Alps,Tyrol, with a key to adult species of the genus

Two new species of rhagidiid mites are described from Oetztal Alps, Tyrol, Troglocheles archetypica n. sp. and T. aggerata n. sp. Their interspecific relationships are discussed and two new species-groups, T. strasseri and T. vornatscheri, are defined. A key to the known adult species of the genus Troglocheles Zacharda is given. Phylogenetic and evolutionary relationships among the known talus- and cave-dwelling species of this genus are briefly outlined, including the possibilities of sympatric versus allopatric speciation.     

A new genus of viviparous gyrodactylid (Monogenea) from the Great Barrier Reef,Australia with descriptions of seven new species

Acanthoplacatus gen. nov., a new genus of viviparous gyrodactylid, is described from the fins and skin of siganid fishes from the Great Barrier Reef, Australia. The genus is characterized by a muscular, tube-like haptor with 16 marginal hooks on the posterior margin. The ventral lobe of the haptor is located anteriorly relative to the dorsal lobe and contains a pair of hamuli and a ventral bar with posteriorly-projecting ventral bar membrane. A dorsal bar is absent. Five pairs of posterior gland cells surround the posterior terminations of the gut. The male copulatory organ is a muscular, non-eversible bulb with several spines around the distal opening. Species of Acanthoplacatus have a bilateral excretory system consisting of six pairs of flame cells and a pair of excretory bladders. Seven new species are described: Acanthoplacatus adlardi sp. nov. and A. amplihamus sp. nov. from Siganus punctatus (Forster, 1801), A. brauni sp. nov. from S. corallinus (Valenciennes, 1835), A. parvihamus sp. nov. from S. vulpinus (Schlegel and Mueller, 1845), A. puelli sp. nov. from S. puellus Schlegel, 1852, A. shieldsi sp. nov. from S. lineatus (Valenciennes, 1835) and A. sigani sp. nov. from S. fuscescens (Houttuyn, 1782). Species can be discriminated by shape and size of the hamuli, marginal hooks and ventral bar and by male copulatory organ sclerite morphology. Three species (A. brauni sp. nov., A. shieldsi sp. nov. and A. sigani sp. nov.) were assessed for seasonal variation of sclerite size. Ten of thirteen morphological characters showed seasonal variation in size for at least one of the species. The characters were longer in winter except dorsal root tissue cap width. Only one character, marginal hook length, showed significant seasonal variation for all three species. Species of Acanthoplacatus were observed to attach using only the marginal hooks and the role of hamuli in attachment is unclear. The dorsal fin of the host is the preferred site for most species but the anal fin, caudal fin and body surfaces are preferred by some species. Prevalences for species range from 57 to 100%.     

Two new genera of Cryptocephalinae (Coleoptera: Chrysomelidae) from Australasia

Two new genera are described for some species of Cryptocephalinae from the Australasian region. Melatia is erected for 29 species hitherto described in Cadmus Erichson, Cryptocephalus Geoffroy and Lachnabothra Saunders, from New Guinea and nearby islands; Ditropidella for four species described in Coenobius Suffrian and Ditropidus Erichson, from southern Australia.     

A new subfamily of Rhynchohydracaridae (Acari,Hydrachnellae) from the island of Coiba (Panama) with descriptions of new taxa

During an intensive study of the water mite fauna of the island of Coiba (Panama) the following new taxa were found: a new subfamily of Rhynchohydracaridae Lundblad, 1936 with two new genera and species, and a new subgenus of Rhynchohydracarus Lundblad, 1936 with a new species. The female of this genus is described for the first time.     

Two new Oriental genera of Doryctinae (Hymenoptera,Braconidae) from termite nests

Two new genera of the subfamily Doryctinae collected in termite nests are described and illustrated: Termitospathius gen. n. from Sumatra (type species T. sumatranus sp. n.) and Ceylonspathius gen. n. from Sri Lanka (type species C. nixoni sp. n.). It is the first record of the braconids from termite nests in the Old World. The biological features of the Doryctinae species and phylogenetic positions of the new genera are discussed.     

Palaearctic species of Ammoplanus (Hymenoptera: Sphecidae)

The Palaearctic species of the genus Ammoplanus Giraud are revised, based on material of over 1750 specimens from Europe, North Africa and Central Asia. For almost all species it was possible to examine the type material and in six species the lectotypes have been designated, in two cases (A. perrisi and A. marathroicus) the neotypes. As a result 38 species are recognized as valid, keyed out and commented on. Eight species are described as new and four species names are here placed in synonymy. Several species are of wide distribution, which made it necessary to include also those described from Central Asia and Mongolia. The keys are made to all Palaearctic species but no material is known from the regions east of Mongolia, although four undescribed species are available from South-East Asia. The Afrotropical species are listed and most of them were also examined. Two subgenera are recognized in the region; 32 species are classified in Ammoplanus sensu stricto and six in the subgenus Ammoplanellus. In the nominal subgenus the following species are described as new: A. atlasensis from Morocco, A. biscopula from Israel, A. biskrensis from Algeria, A. denesi from Turkey (Anatolia), A. freidbergi and A. kaplanae from Israel, A. minutus from Bulgaria and Turkey and A. strumae from Bulgaria and Greece. New synonymy: A. angelae becomes a junior synonym of rhodesianus (known before only from Africa), A. crudelis a synonym of A. kaszabi, A. handlirschi a synonym of A. marathroicus, A. suarezi a synonym of A. kohlii, A. subcompressus of A. gegen, A. orbiculatus of A. simplex and A. zarcoi of A. kohlii; A. wesmaeli is confirmed as a synonym of A. perrisi. Otherwise the synonymy is corrected under A. bischoffi and the names A. dusmeti and A. curvidens are re-established as valid. In a short review of the African species A. (Ammoplanellus) cradockensis Arnold, 1959 is placed as a new synonym under A. (Ammoplanellus) latiscapus Leclercq, 1959. The nomenclatural changes are explained under the relevant species.     

The Pacific Iassine cicadellid genus Thalattoscopus (Homoptera)

The Pacific Iassine genus Thalattoscopus is revised and distinguished from Batracomorphus on external and male genitalic characters. Of 21 species included, 12 are newly described and two are treated as nomina dubia. A key to species is given, four new synonymies and eight new combinations are established.     

A taxonomic study on the Phtisicidae (Crustacea: Amphipoda) of New South Wales,Australia

The present study reviews the taxonomy of the Phtisicidae (Crustacea: Amphipoda) from the coast of New South Wales, Australia. The following seven species are described; Dodecas decacentrum Stebbing, 1910b, Dodecas hexacentrum Mayer, 1903, Hircella cornigera (Haswell, 1879b), Metaproto novaehollandiae (Haswell, 1879a), Notoprotomima smithi gen. nov., sp. nov., Paraproto sp. and Perotripus sp. Generic diagnoses of Notoprotomima gen. nov., Dodecas, Hircella and Metaproto are provided based on the present materials. Notoprotomima smithi is fully described as a new species of the new genus. Dodecas decacentrum differs from Dodecas hexacentrum by the presence of paired dorsodistal projections on pereonite 2, paired mid-dorsal projections on pereonites 3 and 4 and shorter gill length on pereonites 2 and 3. Hircella cornigera and Metaproto novaehollandiae are described in detail. The larger mature males of M. novaehollandiae possess the unusual massive type of the propodus of gnathopod 2. The extended distribution of Perotripus to the New South Wales coast is noted. A key for these phtisicid amphipods from New South Wales, Australia is provided.
