Three new species of free‐living marine nematodes from the Bohai Sea and Yellow Sea,China

Three new species of marine nematodes belonging to the genera Paranticoma (family Anticomidae) and Parodontophora (family Axonolaimidae) are described from the Bohai Sea and Yellow Sea. Paranticoma tricerviseta sp. nov. is similar to P. bandaenseMicoletzky and Kreis, in the spicules, but can be distinguished by the presence of a ventral projection on the spicules, three regularly arranged cervical setae in both the male and female, and two distinct ventral setae behind the anus. Parodontophora deltensis sp. nov. is close to P. paragranulifera (Timm, ) in the length of the amphids, with the ventral arm of the amphid extending past the base of the stoma, but can be separated by the ratio of dorsal arm length to ventral arm (0.36–0.55 versus 0.20–0.25) and the position of the excretory pore (at the middle level versus top level of the stoma), distinctive cervical setae arrangement and a longer renette cell. Parodontophora wuleidaowanensis sp. nov. is close to P. danker Belogurov and Kartavtseva, in the form of the amphids, but can be distinguished by the longer length of the ventral arm of the amphids and the distinctive arrangement of cervical setae.     

Four new records and a new species of Dactylokepon Stebbing, 1910 (Epicaridea: Bopyridae: Ioninae) from Chinese waters

Five species of the parasitic isopod genus Dactylokepon are described from brachyuran crabs and a scyllarid shrimp collected in Chinese waters. Four species are first recorded from this region, D. richardsonae Stebbing, 1910 Stebbing, T. R. R. 1910. Isopod from the Indian Ocean and British East Africa..

In addition, one species is new to science, D. barbuladigitus n. sp. infesting Liagore rubromaculata (De Haan). Six brachyuran crabs are reported for the first time as hosts of bopyrids. The new species is distinguished from other species of Dactylokepon in having a prominent trifid frontal lamina and a distinct digitate barbula.     

Composition of meiobenthonic Platyhelminthes from brackish environments of the Galician and Cantabrian coasts of Spain with the description of a new species of Djeziraia (Polycystididae,Kalyptorhynchia)

From 1997 to 1999, the fauna of free‐living Platyhelminthes of the rias ecosystem was studied along the Galician and Cantabrian coast in northern Spain. In total, 72 platyhelminth species are listed in this study. Forty‐two species represent new records for the Iberian Peninsula, three of which represent new genera records. A new species belonging to the genus Djeziraia (Polycystididae, Kalyptorhynchia), Djeziraia longistyla sp. nov., is described in this paper. In this broad‐scale study, a large data set (27 localities) of the estuaries of northern Spain allowed an analysis of the turbellarian species assemblages and the relation of species distributions to salinity, conductivity, oxygen, temperature, and sediment characteristics. Species assemblages (species diversity) of each habitat of the brackish water ecotone are shown. The present study contributes to knowledge on the ability of adaptation of free‐living Platyhelminthes to regimes of brackish water ecotones.     

Australian species of Sinella (Coecobrya) Yosii, 1956 (Collembola: Entomobryidae)

The Australian members of the subgenus, Sinella (Coecobrya) Yosii, are revised. A new species from Western Australia, Queensland, and the Northern Territory, Sinella (Coecobrya) tropicalis sp. nov., is described, Sinella (Coecobrya) tenebricosa Folsom, 1902 is recorded from Australia for the first time, and new records of Sinella (Coecobrya) communis Chen and Christiansen, 1997 Chen, J‐X. and Christiansen, K.

Annals of the American Society of Entomology, 90: 1–19.  [Google Scholar] are documented. Sinella (Coecobrya) caeca Schött, 1896 is considered a dubious record from Australia.

Caridina pareparensis parvidentata is here regarded as a distinct species. The new taxa are described, figured and compared with congeners.     

Description of four new species of the genus Ampelisca (Amphipoda,Ampeliscidae) from the northeastern and southeastern coasts of Brazil and designation of a neotype for Ampelisca soleata Oliveira, 1954

The present study raises the number of Ampelisca species recorded from the Brazilian coast from 18 to 21. The amphipod fauna of the Brazilian northeast coast is hardly known compared to that of the southeast coast. In this study, we describe three new species from the northeast coast: Ampelisca pseudobicarinata sp. nov., Ampelisca rocasensis sp. nov. and Ampelisca cristianae sp. nov, recorded previously as Ampelisca aff. lobata (Serejo et al. 2000 Serejo, CS, Wakabara, Y and Valério-Berardo, MT. 2000. Taxonomy and geographic distribution of Ampelisca (Amphipoda: Gammaridea) from the Brazilian coast. Polsk Archiw Hydrobiol., 47(3–4): 495–510.  [Google Scholar]). We also report a new record of Ampelisca burkei Barnard and Thomas, 1989 Barnard, JL and Thomas, JD. 1989. A new species, Ampelisca burkei, (Crustacea, Amphipoda) from Florida. Proc Biol Soc Washington., 102(2): 375–384.  [Google Scholar]. From the southeast coast a new species Ampelisca angraensis sp. nov. is described. An obscure species, Ampelisca soleata, which is very similar to Ampelisca brevisimulata, is herein redescribed and a neotype is designated. An updated key with all species of Ampelisca recorded from the Brazilian coast and comments on geographic distribution are given.
