A new species of arboreal salamander (Caudata: Plethodontidae: Pseudoeurycea) from the mountains of Oaxaca,Mexico

Recent surveys of the plethodontid salamander fauna of Oaxaca, Mexico, disclosed the existence of a new, morphologically distinct arboreal species of the genus Pseudoeurycea. The new species, described here, is from the Sierra Mazateca in northern Oaxaca. Sequences of 1833 base pairs of the 16S, cytochrome b and ND4 mitochondrial DNA (mtDNA) genes from the new taxon were used to assess its phylogenetic position. Previous phylogenetic analyses based on mtDNA supported recognition of four clades within Pseudoeurycea: P. bellii, P. gadovii, P. juarezi and P. leprosa-Lineatriton species groups. One additional species, P. unguidentis, was not closely allied to any of the four groups. Re-analysis including the additional sequences reported here establishes a sister-group relationship between the new species and P. unguidentis. Moreover, it supports this clade as part of the P. juarezi species group.     

New species and rediagnosis of Coecobrya (Collembola: Entomobryidae), with a key to the species of the genus

The history of Coecobrya is traced and the genus is redefined. Two new species are described and one known species is redescribed in this paper: Coecobrya lanna sp. nov., Coecobrya tukmeas sp. nov. and Coecobrya aokii (Yoshii, 1995 Yoshii, R. 1995. Notes on Collembola of Vanuatu. Acta Zool Asiae-Orient., 3: 43–50.  [Google Scholar]). Additional details are provided for three other species Coecobrya guanophila Deharveng, 1990 Deharveng, L. 1990.

New species of the rhagidiid genus Foveacheles (Acari: Prostigmata: Eupodoidea) with a lyrifissure-like structure on the chelicerae

Three new species are described: Foveacheles gigantea n. sp., F. halltalensis n. sp. and F. proxima n. sp. Their phylogenetic relationships are discussed. The new gigantea-species group is erected, based on the presence of a lyrifissure-like structure near the base of the fixed digit of the chelicera. A cheliceral lyrifissurelike structure has not been previously observed and described in literature on mites of the superfamily Eupodoidea. The definition of the genus Foveacheles is slightly adapted.

Stephonyx californiensis sp. nov. (Amphipoda: Lysianassoidea: Uristidae), a new bathyal scavenger species from the Central Gulf of California,Mexico, and comments on the bathymetric and geographic distribution of the Stephonyx species group

A new species of scavenger amphipod of the genus Stephonyx is described and illustrated. The specimen was caught at 1150 m depth with a modified rectangular lobster trap positioned on the sea bottom in the central Gulf of California, Mexico. The new species is characterised by the absence of eyes; the lateral cephalic lobes medially developed and acute; antennae subequal in length; gnathopod 1 chelate, dactylus simple with three distal stout setae, inner margin sinuous with minute setae; gnathopod 2 subchelate, carpus with ventral margin crenulate, propodus subovate, palm deeply excavate, and dactylus slightly shorter than palm; maxilliped inner plate laceolate, with seven marginal nodular robust setae, distally; telson, each lobe with two dorsal robust setae, distal margin truncated, with one penicillate and two simple setae, in addition to two short spines. Stephonyx californiensis sp. nov. is morphologically similar to S. arabiensis, S talismani, S. laqueus and S. perexcavatus. The new species increases the number of Stephonyx species around the world to 14, with one species inhabiting from the continental shelf to abyssal depths (to 3000 m), 11 species occurring in bathyal depths (201–2000 m), and two other species restricted to abyssal depths (2001–4000 m).

New species and records of earthworms from Jamaica with notes on the genus Eutrigaster Cognetti, 1904 (Octochaetidae: Oligochaeta)

Details are presented of earthworm collections from Jamaica. Eleven species are reported, eight being new records of which two are new species, to bring the total number of species known from the island to 16 and the number of families represented to six. The geographical affinities of each species and its faunal status are summarized. The new species are members of the genus Eutrigaster Cognetti (Octochaetidae) whose validity is reviewed; a table is provided for the identification of the 11 Central American and Caribbean species currently included in 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.     

Four new species of the genus Synosis Townes (Hymenoptera: Ichneumonidae) from the eastern Andes of Peru and key for the New World species

Synosis Townes is a widely distributed genus of the family Ichneumonidae; most species recorded occur in the Old World and only two were formerly known to occur in the New World. Herein we describe Synosis rubinus sp. nov., Synosis cosnipatensis sp. nov., Synosis gauldi sp. nov. and Synosis townesi sp. nov. collected in various Peruvian cloud forests. A generic diagnosis and a key to the species occurring in the New World is also presented. http://www.zoobank.org/urn:lsid:zoobank.org:pub:8E5FA67F-F80A-4D78-8E5E-7CC8D6662396     

Casinaria,a paraphyletic ichneumonid genus (Hymenoptera), and a revision of the Australian species

The Australian species of the campoplegine ichneumonid genus Casinaria are revised and an illustrated key is provided for their identification. Eleven species are recognized, but one is not formally named. The Australian species are referable to two morphologically and biologically distinct groups, the meridionalis species-group (containing amarilla sp. nov., hesperiophaga sp. nov. and meridionalis (Turner)) which are parasitoids of hesperiid larvae, and the siccata species-group (containing eremica sp. nov., micra sp. nov., mythologica sp. nov., pavlova sp. nov., siccata sp. nov., virgata sp. nov., woowonga sp. nov. and species A) which parasitize the larvae of a variety of smaller moths. The holophyly of each of the two species-groups is demonstrated, but characters supporting the holophyly of the genus could not be found, suggesting that Casinaria, as currently recognized, may either be paraphyletic or polyphyletic.     

A new species of dorid nudibranch of the genus Taringa Marcus, 1955 (Mollusca: Opisthobranchia) from the southern Iberian peninsula,with remarks on world species of the genus

New records of Bathynellacea (Syncarida,Bathynellidae) in North America: three new species of the genus Pacificabathynella from Montana,USA

Three new species of the genus Pacificabathynella Schminke and Noodt, 1988 Schminke, H K and Noodt, W. 1988. Groundwater Crustacea of the order Bathynellacea (Malacostraca) from North America. J Crustacean Biol., 8(2): 290–299.  [Google Scholar] are described from groundwater aquifers in glaciated North America (Montana, USA). This is the first time that this genus, known previously only from the state of California, has been documented in Montana. Pacificabathynella and Paradoxibathynella Serban, 2000 Serban, E. 2000. Uenobathynella n.g., Parauenobathynella n.g., Morimotobathynella n.g., Nihobathynella n.g. et Paradoxibathynella n.g., Bathynellinae du Japón (Bathynellidae, Bathynellacea, Podophallocarida). Travaux Inst Spéol “Émile Racovitza”, 36: 3–61.  [Google Scholar] are the only genera that show sexual dimorphism in thoracopod VI. Pacificabathynella kalispellensis sp. nov. has several unique features: the setal formula of the antenna (0/2+exop/3/12/6/8/5); the setal formula of the maxilla (7/4/7/6); the presence of an epipod on thoracopod II; tufts of setulae and abundant setae on the basipod and endopod of thoracopods I to V; the epipod of thoracopod VIII female three times longer than the basipod; three smooth setae on the exopod of the female thoracopod VIII; eight spines on the endopod of the uropod and the endopod longer than the sympod, whereas the opposite is typical. Pacificabathynella stanfordi sp. nov. has several unique features: only five setae on the exopod of thoracopods II to VII, while six setae are common in the genus; only six setae on the second segment of the first pleopod; five spines on the endopod and seven setae on the exopod of the uropod. Pacificabathynella ruthae sp. nov. is the largest species and has several unique features: antennule equal in size to the antenna, whereas in the rest of the species of the genus the antenna is larger; the projection of the inner lobe of the male thoracopod VIII is bidentate and there are six spines on the endopod and nine setae on the exopod of the uropod. The three new species have slight differences in the pars molaris of the mandible and in thoracopod VIII of males, and there are other minor differences between the females and the species Pacificabathynella sequoiae. The new taxa, together with the new genus Montanabathynella described separately, represent a 30% increase in North American taxa. Considering the glaciated landscape and the fragmented nature of alluvial aquifer habitat, we believe that there is a profound lack of critical knowledge of the biogeography and biodiversity of syncarids in North America.     

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.
