The West Palaearctic species of Fidiobia Ashmead, 1894 (Hymenoptera: Platygastroidea)

One new genus Songmachilis and six new species in family Machilidae are described from China: Songmachilis xinxiangensis gen. sp. nov., Coreamachilis songi sp. nov., Pedetontinus jiuzhaiensis sp. nov., Pedetontinus maijiensis sp. nov., Pedetontinus taishanensis sp. nov. and. Pedetontinus wudangensis sp. nov. A key to all Chinese species of Pedetontinus is given. We also examined the relationships among Chinese machilids based on partial sequences of mitochondrial cytochrome c oxidase subunit I (COI). The molecular study further supported the species status of the six new taxa.     

New taxa of the family Trochometridiidae (Acari: Heterostigmata) associated with insects from Iran

A new genus and two new species of mites of the family Trochometridiidae (Acari: Heterostigmata) are described from Iran: Neotrochometridium sensillum Hajiqanbar and Khaustov gen. nov., sp. nov. associated with two carabid beetles and Trochometridium iranicum Hajiqanbar and Khaustov sp. nov. associated with a halictid bee. We also present the first report of two previously described species. These findings provide the first record of the family Trochometridiidae from Iran. The chaetotaxy of tarsus I of the family is discussed and a key to world genera and species is provided.     

Two new species of the genus Sinella Brook, 1882 (Collembola: Entomobryidae) from East China

Two new species, Sinella hexaseta sp. nov. and Sinella pauciseta sp. nov., collected from East China, Anhui and Zhejiang provinces, respectively, were described. Both are easily discriminated from each other and all known Sinella species by their unique dorsocentral chaetotaxic patterns on Abd. IV. In S. pauciseta sp. nov., postlabial setae H_1–4 are ciliate, which are smooth in all other known species of the genus.     

A new genus with three new species of copepods from the family Diaixidae (Crustacea: Calanoida), and a redefinition of the family

Plankton samples taken in the Gulf of Carpentaria, Australia, yielded material of a new genus containing 3 new species: Anawekia spinosa gen. nov. et sp. nov., A. robusta sp. nov. and A. bilobata sp. nov., which are described herein. The family Diaixidae now contains 12 described species in 2 genera, 9 being in the genus Diaixis. It is noted that 3 of the Diaixis species (including the type species) share some features which are not shared with the remaining 6 species, and that these latter species should probably be placed into a third genus. An amplified redefinition of the family is given.     

Two new palaemonid shrimps (Crustacea: Decapoda) from the Australian North West Shelf

Two palaemonid shrimps, from about 80 and 50 m on the Australian North West Shelf, are described and illustrated. A new genus, Carinopontonia, is designated for the single incomplete specimen of C. paucipes sp. nov. The new genus is most closely related to the genus Dasycaris Kemp, 1922. A single specimen of a second shrimp can be referred to Apopontonia Bruce, 1977, but to neither of the known species, and it is now described as A. tridentata sp. nov.     

A new genus and species of terrestrial isopod from Malaysia (Crustacea,Oniscidea, Platyarthridae)

A new terrestrial isopod, Cephaloniscus sociabilis gen. nov., sp. nov., from Fraser Hill in central Malaysia, is described and illustrated. The new genus belongs to the family Platyarthridae and is distinguished from other members of the family by the characteristic structure of the cephalon. The specimens were collected from the nest of the termite Hospitalitermes sp. (near medioflavus Holmgren) together with the ant Centromyrmex hamulatus (Karavaiev).     

Report on Crassispirinae Morrison, 1966 (Mollusca: Neogastropoda: Turridae) from the China Seas

The present paper reports 32 turrid species from the China Seas, belonging to eight genera of the subfamily Crassispirinae of the family Turridae. Four new species are described: Funa cretea sp. nov., Inquisitor plurivaricis sp. nov., Inquisitor vividus sp. nov. and Ptychobela resticula sp. nov. Eight species are recorded for the first time from the China Seas.     

Chilarboreus gen. nov., a new genus of Chilean Scirtidae (Coleoptera: Scirtoidea), with descriptions of three new species

The genus Chilarboreus gen. nov. is described from Nothofagus forests of Chile to accommodate three new species: Chilarboreus fossulatus sp. nov., Chilarboreus acuticollis sp. nov. and Chilarboreus darwini sp. nov. The genus is subdivided into two subgenera: Chilarboreus subgen. nov. (type species: C. fossulatus) and Pictarboreus subgen. nov. (type species: C. darwini). Identification keys to the genera of Chilean Scirtidae and the species in the genus Chilarboreus are provided. The state of knowledge of Chilean Scirtidae is summarized. The position of Chilarboreus within Scirtidae and the phenomenon of wing reduction in Scirtidae are discussed.     

Report on the Raphitomidae Bellardi, 1875 (Mollusca: Gastropoda: Conoidea) from the China Seas

Twenty-seven Raphitomidae species belonging to nine genera, are recorded from the China Seas, including two new species, which are described here: Asperdaphne paramoretonica sp. nov., Daphnella inangulata sp. nov. Eight species are recorded for the first time from the China Seas.     

The taxonomy and biology of a new species Pontonema (Nematoda,Oncholaimidae) dominant in organically polluted sublittoral sediments around Scotland,with a review of the genus

A new species of free living marine nematode, Pontonema alaeospicula sp. nov., is a dominant member of the fauna in three organically polluted sublittoral habitats off the Scottish coast. The species is described and the genus reviewed. A schematic pictorial key to the genus is provided. Some notes on the biology of P. alaeospicula sp. nov. are given, based on initial studies of the population in situ and in laboratory culture.     

Genus Baseodiscus (Nemertea: Heteronemertea): Molecular identification of a new species in a phylogenetic context

A new heteronemertean, Baseodiscus jonasii sp. nov., is described from Guadalcanal, Solomon Islands. It resembles B. delineatus in inner morphology but can be distinguished from this species by its different colour pattern and differences in the nucleotide sequence of the mitochondrial 16S rRNA gene. The monophyletic status of the genus is investigated by reconstructing the phylogeny of six specimens from four species assigned to this genus, together with 22 specimens from nine other heteronemertean genera, using parsimony and Bayesian analysis. The results imply that Baseodiscus is a monophyletic group while several other heteronemertean genera are non‐monophyletic.     

New family and genus Rostrocalanus gen. nov. (Crustacea: Calanoida: Rostrocalanidae fam. nov.) from deep Atlantic waters

Two new species of a new genus and family Rostrocalanidae of benthopelagic clausocalanoid copepods are described from female specimens collected from abyssal depths close to the sea bed in the tropical Atlantic. Rostrocalanus gen. nov. shares the presence of sensory setae on maxilla with other bradfordian families of Clausocalanoidea, but does not fit the diagnosis of any of these families. A family Rostrocalanidae is established for this new genus and is defined by the following derived characters: four‐segmented exopod of mandible supplied with four setae; distal basal endite of maxillule fused to endopod and bearing five setae in total; endopod of maxilla furnished with six worm‐like sensory setae; arrangement of setal numbers on praecoxal endites of maxilliped syncoxa as 0, 1, 2. The establishment of a new clausocalanoidean family sheds new light on the morphological diversity of bradfordian benthopelagic copepods and adds to the biodiversity of the deep‐water calanoid fauna.     

A new genus and six new species of the Parabathynellidae (Bathynellacea,Syncarida) from the Kimberley region,Western Australia

Six new species of a new genus of the Parabathynellidae are described from the Kimberley Region, Western Australia. The erection of the new genus, Kimberleybathynella gen. nov., is based on the two‐segmented antenna, the partial fusion of the second and third segments of the maxilla, and the setal condition of the uropodal exopodite, where the outer seta is longer than the inner one. The one‐segmented exopodite of thoracopods I–VII and hemispherical form of male thoracopod VIII suggest the close relationship of Kimberleybathynella to the genus Atopobathynella.     

A new damsel-dragonfly from the Mesozoic of China with a hook-like male anal angle (Odonata: Isophlebioptera: Campterophlebiidae)

A new genus and species of campterophlebiid dragonfly, Angustiphlebia mirabilis gen. nov. et sp. nov., is described from the Jiulongshan Formation in China. It has some remarkable venational structures, i.e. a hypertrophy of the male hind wing anal angle, a quite long gaff, and a secondary branch of the anal anterior near subdiscoidal cell in hind wing, supporting the hypothesis of a sister-group relationship with the genus Oreophlebia. These new data will help to solve the phylogenetic relationships within the Campterophlebiidae. http://www.zoobank.org/urn:lsid:zoobank.org:pub:16E602E6-3567-44D7-BF64-95A6597E55DE     

A new genus and two new species of Parastenocarididae (Copepoda: Harpacticoida) from southeastern India

Indocaris gen. nov. with two new species, Indocaris imbricata sp. nov. and Indocaris inopinata sp. nov., and also for the already known Indocaris tirupatiensis (Ranga Reddy 2011a) comb. nov. – all from the groundwaters in peninsular India. The highly diagnostic synapomorphy of the new genus is a composite character associated with the male leg 4 basis: five or six prominent, imbricate, enlarged, petal-like spinules, arranged as a semi-whorl at the insertion of the endopod and increasing in size from internal to external. Another distinctive feature of the same appendage is that its one-segmented endopod is dilated or bulbous in the proximal half, produced distally into an incurved spiniform or horn-like structure about as long as the corresponding first exopodal segment, and ornamented with three or four fine spinules on the subproximal outer margin. The three species also share a unique constellation of other salient morphologic features, which along with the phylogenetic position of Indocaris gen. nov. within the family Parastenocarididae are discussed. Indocaris gen. nov. has closest phylogenetic affinity with the Neotropical Remaneicari Jakobi, 1972. A short note on the ecology and biogeography of the parastenocaridid species of the Indian subcontinent is provided besides a key for their identification.     

A new species of marine nemertean from Anglesey,North Wales,with a discussion of the genus Paroerstedia Friedrich, 1955

A new species of marine nemertean, Paroerstedia nigrimaculata sp. nov., is described and illustrated from a single specimen found among Corallina in a lower shore rock pool at Rhosneigr, Anglesey, North Wales. No Paroerstedia species has been recorded previously from the British Isles. The systematics of the genus and its contained species are discussed.     

Frenguelliidae,a new family of dragonflies from the earliest Eocene of Argentina (Insecta: Odonata): phylogenetic relationships within Odonata

The new dragonfly family Frenguelliidae based on Frenguellia patagonica gen. nov., sp. nov., is erected from the earliest Eocene of Patagonia (Argentina). Its phylogenetic relationships within the Zygoptera and Epiproctophora (sensu Bechly, 1996) are discussed. The new family seems to be related to Sieblosiidae from the Oligo-Miocene of Eurasia; and both could pertain to the basal lineage of Epiproctophora. These attributions are not supported by the known stratigraphic data and could be explained by the incompleteness of the fossil record of Odonata, mainly in the Triassic.
