A new subgenus of the genus Colastes Haliday (Hymenoptera: Braconidae: Exothecinae) for species reared from bracket fungi,with description of two new species from Europe

A new Holarctic subgenus (Fungivenator subgen. nov.) of the genus Colastes Haliday, 1833 (Hymenoptera: Braconidae: Exothecinae) is proposed for a group of species that, as far as is known, has its larvae living on hosts in bracket fungi. The type species (Colastes sandei sp. nov. from Netherlands, Germany and England) and a second species (C. fritzeni sp. nov.) from Finland are described and illustrated. A key to the five known species is included.

A study on amphipods from the superfamily Stegocephaloidea Dana 1852 from the northeastern Pacific region: systematics and distributional ecology

Nine species (including five new to science) of non-lafystiid stegocephaloid amphipods have been recognized within the collections of the Canadian Museum of Nature from the NE Pacific (Alaska to Oregon), viz. Acanthonotozoma rusanovae Bryazgin 1974 (Acanthonotozomatidae), Iphimedia rickettsi Shoemaker 1931 (Iphimediidae), Parandania boecki (Stebbing 1888), Phippsiella cascadiensis n.sp., Stegocephalexia penelope n. gen., n. sp., Stegocephalopsis mamillidacta n. sp. (Stegocephalidae). Odius kelleri Bruggen 1907 is reallocated to Cryptodius n. gen., and C. unguidactylus n. sp. and Imbrexodius oclairi n. gen., n. sp. (Odiidae) are also described. Keys are presented which allow the genera of Odiidae of the world, and of this collection of species, to be distinguished.     

Description of new Ceratitis MacLeay (Diptera,Tephritidae) species from Africa

As an addition to earlier published systematic revisions of the genus Ceratitis MacLeay, five new species are hereby described: Ceratitis (Pardalaspis) millicentae sp. n., C. (Ceratalaspis) oraria sp. n., C. (C.) perisae sp. n., and C. (C.) perseus, sp. n. all from Kenya, and C. (C.) ealensis sp. n. from the Democratic Republic of Congo. Their relationship with closely allied species within the respective subgenera is discussed and differentiating characters given.     

Heterotrophic flagellates (Protista) from marine sediments of Botany Bay,Australia

Heterotrophic flagellates (protozoa) occurring in the marine sediments at Botany Bay, Australia are reported. Among the 87 species from 43 genera encountered in this survey are 13 new taxa: Cercomonas granulatus n. sp., Clautriavia cavus n. sp., Heteronema larseni n. sp., Notosolenus adamas n. sp., Notosolenus brothernis n. sp., Notosolenus hemicircularis n. sp., Notosolenus lashue n. sp., Notosolenus pyriforme n. sp., Petalomonas intortus n. sp., Petalomonas iugosus n. sp., Petalomonas labrum n. sp., Petalomonas planus n. sp. and Petalomonas virgatus n. sp.; and seven new combinations, Carpediemonas bialata n. comb., Dinema platysomum n. comb., Petalomonas calycimonoides nom. nov., Petalomonas christeni nom. nov., Petalomonas physaloides n. comb., Petalomonas quinquecarinata n. comb. and Petalomonas spinifera n. comb. Most flagellates described here appear to be cosmopolitan. We are unable to assess if the new species are endemic because of the lack of intensive studies elsewhere.     

New taxa of Rhagidiidae (Acari: Prostigmata) from North America. Part V. Genus Robustocheles Zacharda,with a key to world species of the genus

Six new species of rhagidiid mites from the Nearctic region, Robustocheles (R.) pascuaria n.sp., R. (R.) similis n.sp., R. (Mexia) longichelae n.subgen, n.sp., R. (Lewia) lacustris n. sp., R. (L.) obscuritata n. sp. and R. (L.) spinaea n. sp., are described. Additional morphological data are given for R. infernalis Zacharda and Elliott which is placed in the new subgenus Mexia. A key to adults of the known four subgenera and 15 species of the genus Robustocheles Zacharda of the world is presented.     

First collections of water mites (Acari: Hydrachnidia) from Honduras: descriptions of six new species

First collections of water mites (Acari: Hydrachnidia) from Honduras indicate a rich fauna. Nineteen species from just three sites yielded six species new to science. New species described and discussed are: Hydrodroma moralesi n. sp., Flabellifrontipoda triscutata n. sp., Monatractides angelae n. sp., Pseudotorrenticola espinasseae n. sp., Atractides jenniferae n. sp. and Recifella cusucoensis n. sp.     

Cladistics and taxonomy of the Afrotropical Empis (Coptophlebia) chrysocera-group (Diptera,Empididae)

The Afrotropical Empis (Coptophlebia) chrysocera-group (Diptera: Empididae) is defined on the basis of two synapomorphies, namely epandrial lamellae connected anteriorly and male cerci made up of an anterior almost bare lobe and a posterior bristled lobe. This group includes 10 species: E. (C.) brazzavillensis sp. n., E. (C.) barbitos Smith, E. (C.) juxtaripa sp. n., E. (C.) lyra Smith, E. (C.) plumata sp. n., E. (C.) chrysocera Collin, E. (C.) cuthbertsoni Smith, E. (C.) machipandensis Smith, E. (C.) samaruensis sp. n. and E. (C.) singulare sp. n. All species are described and keyed. The relationships between these species are established and two complexes of species distinguished. The Empis (Coptophlebia) chrysocera-group apparently occurs everywhere in the Afrotropical region except South Africa.     

A revision of the genus Ceratomerus (Diptera: Empididae: Ceratomerinae) of New Zealand

The genus Ceratomerus Philippi (Diptera: Empididae; Ceratomerinae) of New Zealand is revised and a key to species given. Thirteen species are recognized and the following new species are proposed: C. biseriatus sp. nov., C. flavus sp. nov., C. earlyi sp. nov., C. melaneus sp. nov., C. brevifurcatus sp. nov., C. tarsalis sp. nov. and C. vittatus sp. nov. The biology and phylogeny are briefly discussed.     

Deep sea swimming crabs of the Charybdis miles species group in the western Indian Ocean (Crustacea: Decapoda: Portunidae)

The deep-sea species of the Charybdis miles group occurring in the western Indian Ocean are revised on the basis of recent collections obtained by German and Russian expeditions. Two new species are described, Charybdis meteor sp. n. from the Straits of Bab el Mandeb and Charybdis crosnieri sp. n. from the insular margins and seamounts of the western Indian Ocean, which has been previously identified as Charybdis sagamiensis Parisi, 1916. The C. miles group represents a lineage with a probably relatively recent tendency for submergence which culminated in the formation of C. acutidens Türkay, 1986, a characteristic species of the deep Red Sea water mass.     

New species of Pauropodidae (Myriapoda: Pauropoda) from Nanjing,China

Six new species in the family Pauropodidae are described from China: Allopauropus disphaeroides sp. n., A. crassescens sp. n., A. apicalis sp. n., A. nanjingensis sp. n., Pauropus dorsappendix sp. n., and Stylopauropus zijinensis sp. n.     

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 revision of the genus Siamthelphusa Bott, 1968 (Crustacea: Decapoda: Brachyura: Parathelphusidae), with descriptions of five new species from Thailand

The taxonomy of the northern Peninsular Malaysian and Thai freshwater crab genus Siamthelphusa Bott, 1968 (Crustacea: Decapoda: Brachyura: Parathelphusidae) is revised. Nine species are recognized: S. improvisa (Lanchester, 1901), S. holthuisi Naiyanetr and Ng, 1990, S. retimanus n. sp., S. paviei (De Man, 1898), S. acutidens n. sp., S. faxoni (Rathbun, 1905), S. transversa n. sp., S. nan n. sp., and S. variegata n. sp. A neotype is designated for S. improvisa (Lanchester, 1901), the type species of the genus.     

A revision of Tachyphron Brown and description of two new genera within the Ariphron group (Hymenoptera: Tiphiidae)

The Australasian genus Tachyphron Brown is revised, and two new New Guinean genera, Deuterothynnus gen. n. and Heligmothynnus gen. n., described. Fifteen species are included in Tachyphron of which seven are described as new (T. aculeatus sp. n., T. athertonensis sp. n., T. mantonensis sp. n., T. neosubfragilis sp. n., T. nigrisetatus sp. n., T. planus sp. n. and T. townsvillensis sp. n.), and a further two, Aelurus comatus Smith and Aelurus fragilis Smith, transferred from Tachynomyia. Thynnus insularis Smith is transferred from Tachynomyia Guérin to Deuterothynnus and a further three new species, D. fulvicentratus sp. n., D. fulvisetatus sp. n. and D. parallelus sp. n. described. Aelurus atratus Cameron and Takyomyia sabronensis Kimsey are transferred from Tachynomyia and Tachyphron, respectively, to Heligmothynnus and a further two new species, H. microspinus sp. n. and H. neoaratus sp. n. described. T. megacephala (Turner) is synonymized with Tachynoides flavopicta (Ritsema) and, therefore, removed from Tachyphron. A key to the Ariphron group of genera is provided, as well as keys to the males of Tachyphron, Deuterothynnus and Heligmothynnus, although the male of D. insularis is associated tentatively with the female holotype only on the basis of collection records. Only the females of D. insularis, T. armidalensis Brown and T. subtriangularus Brown are known, the latter two being described for the first time. Evidence is presented to suggest that T. subtriangularus may be bivoltine in northern Australia.     

New species of Doliodrilus and other Limnodriloidinae (Oligochaeta,Tubificidae) from Hainan and other parts of the north-west Pacific Ocean

Thirteen species of Limnodriloidinae (Tubificidae) are recorded from marine and brackish-water habitats of Hainan Island, southern China, including 11 species of Doliodrilus and two species belonging to Limnodriloides. Eight species are new to science: D. bisaccus sp. n. (types from Japan), D. longidentatus sp. n. (types from Hong Kong), D. ciliatus sp. n., D. adiacens sp. n., D. fibrisaccus sp. n. (also from Fiji), D. brachyductus sp. n., D. bidolium sp. n. and D. chinensis sp. n. In addition, material of D. puertoricensis Erséus and Milligan, 1988, from New Caledonia, is briefly described. This study shows that Doliodrilus is unexpectedly species-rich in Asian seas, in particular, around Hainan. Including an unnamed species from this island, the known members of this genus increase from three to 12.     

Six new feather mite species (Acari: Astigmata) from the carolina parakeet Conuropsis carolinensis (Psittaciformes: Psittacidae), an extinct parrot of North America

We describe six new feather mite species collected from museum skins of the carolina parakeet Conuropsis carolinensis Linnaeus, 1758, which lived in North America and became extinct at the beginning of the 20th century: Genoprotolichus simplex sp. n., Lopharalichus beckeri sp. n., Neorhytidelasma conuropsis sp. n. (Pterolichidae: Pterolichinae), Chiasmalges carolinensis sp. n. (Psoroptoididae: Pandalurinae), Fainalges gracilitarsus sp. n., and Protonyssus proctorae sp. n. (Xolalgidae: Ingrassiinae). Brief comments on the current systematic state and host associations of these feather mite genera are provided.     

Poecilostomatoid Copepods from an Intertidal Mud Flat in the Yellow Sea

Thirteen new species and one new genus of poecilostomatoid copepods are described from intertidal mud flats in the central west coast of the Korean Peninsula facing the Yellow Sea. Nine species are found in association with invertebrates: Hemicyclops ventriplanus n. sp. from the decapod crustacean Upogebia major (De Haan); Clausia lobata n. sp. from the polychaete Marphysa sanguinea (Montagu); Presynaptiphilus minutus n. sp. from the ophiuroid Amphiura sinicola (Matsumoto); Synaptiphilus longicaudus n. sp. and Enterophilus cercomegalus n. gen. et n. sp. from the holothurian Protankyra bidentata (Woodward and Barrett); Goidelia pelliviva n. sp. from an echiuroid Thalassema sp.; Lichomolgus bullatus n. sp. from the bivalve Striarca (Didimacar) tenebrica (Reeve); Critomolgus nudus n. sp. from the pennatulacean Virgularia gustaviana (Herklots); and Notoxynus tertius n. sp. from the sea anemone Cerianthus filiformis Carlgren. The other four species are found in stagnant water on the mud flat: Kelleria vaga n. sp., Macrochiron anormalum n. sp., Pseudomacrochiron urostenum n. sp. and Pseudanthessius dentatus n. sp.     

New data on Hydrobiidae systematics: two new genera from the Iberian Peninsula

The taxon Caprella acanthifera auct., usually considered to be one ‘highly variable’ species, is shown here to consist of a number of closely related species. In this paper three species of the group lacking an axillary spine near the insertion of gnathopod 2 are described and illustrated; the taxa with an axillary spine will be dealt with in a separate paper. This paper redefines Caprella acanthifera Leach 1814, sensu stricto; the nominal taxa C. hystrix, C. calva, C. aspera, and C. leptonyx are considered to be junior synonyms. Also described are C. stella sp.n., from starfish at the Azores and C. cavediniae sp.n., living among algae in the Mediterranean. The sources of apparent morphological variability in caprellids are discussed.     

The genus Cremastobaeus Ashmead (Hymenoptera: Scelionidae: Cremastobaeini) from India

Cremastobaeus belonging to the monotypic tribe Cremastobaeini is represented by 24 species worldwide. Only two species, C. indicus Mukerjee and C. unicolor Rajmohana are known from India. Surveys conducted from different parts of India including the remote Andaman and Nicobar islands resulted in 22 species of Cremastobaeus of which 20 are new to science. These 20 species are C. boolei sp. nov., C. breviabdominus sp. nov., C. cornutus sp. nov., C. eila sp. nov., C. foveatus sp. nov., C. fuscus sp. nov., C. longigaster sp. nov., C. luteus sp. nov., C. mahaviraii sp. nov., C. nicobarensis sp. nov., C. nigricephalus sp. nov., C. nigrifemoralis sp. nov., C. parallelogaster sp. nov., C. robustus sp. nov., C. suvarnadeha sp. nov., C. tanugatra sp. nov., C. valmikii sp. nov., C. variegatus sp. nov., C. varuna sp. nov. and C. yoganarasimha sp. nov. The main diagnostic characters are shape and size of metanotum, horn on T1 and sculpture of metasomal tergites. All 22 species are imaged and keyed.

Two new genera and five new species of the feather mite subfamily Proctophyllodinae (Astigmata: Proctophyllodidae) from suboscine birds in Brazil

Two new genera and five new species of feather mites of the family Proctophyllodidae are described from passerine birds from Brazil: Tyranniphyllodes pitangi gen. n., sp. n. from Pitangus sulphuratus (Tyrannidae); Atrichophyllodes delalandi gen. n., sp. n. from Corythopis delalandi (Tyrannidae); A. mentalis gen. n., sp. n. from Dysithamnus mentalis (Thamnophilidae); Anisophyllodes candango sp. n. from Elaenia chiriquensis (Tyrannidae); and Platyacarus sittasomi sp. n. from Sittasomus griseicapillus (Dendrocolaptidae). The discovery of these taxa might give data for a better understanding of the evolution of the family Proctophyllodidae in general and the dispersion of these mites on passerines in South America in paricular.
