The expedition "Atelier Lifou 2000" collected benthic fauna at the island of Lifou, Loyalty Islands, New Caledonia, in November of2000. This isa taxonomic account of the brittle stars found. 94 species were identified, 51 of them new for the region, and seven new to science, increasing the total number of species known from the New Caledonia region to 204. New species are described in the genera Squamophis, Astroceras, Astrogymnotes, Ophiochondrus, Ophiomoeris, Ophiozonella and Am-phipholis. Three species and a subspecies are revised, one of them placed in a new genus. The taxonomic status of Euryale Lamarck, 1816, a junior homonym of EuryalePeron & Lesueur, 1810 (a medusa), is stabilized by formally establishing precedence over the senior name.
查看更多>>摘要：The pandalid genus Plesionika Bate, 1888 includes 92 species and has a widespread distribution. The new Plesionika species described herein was sampled by the oceanographic program REVIZEE Central (Fishery) at the Central Brazilian coast (from 11°S to 22°S) in depths ranging from 200 to 2000 m using ARROW and GOV nets. Additional material of the new species from the collection of Universidade Federal do Rio Grande (FURG), sampled at South Brazilian coast was also examined. Plesionika revizeei n. sp. is closely related to P. willisi (Pequegnat 1970), and the main feature that distinguishes these two species is the presence of epipods on pereopods 1-4 in the new species. This study provides a full description of the new species and an identificationkey to the Southwestern Atlantic species of Plesionika.

Both species were collected from soil under hazelnut trees, Cory-lusavellana L. (Betulaceae) in Ardabil province, Iran. A key to the Iranian species of Stigmaeus is provided.
