摘要

一种新的南极洲等足类动物——Oxyarcturus holoacanthus sp. 11 .在阿根廷“Puerto Deseado”号旅游船“Talud Continental III”考察期间，在马德普拉塔海底峡谷2950米深处采集了7个标本，并对其进行了全面描述。Oxyarcturus holoacanthus sp. nov.与O. spinosus (bedard, 1886)有密切的关系，可以通过其身体的脊柱模式来区分。书中详细描述了尖角兽属和南极科的一个新特征——阴茎板。O. dubius (Kussakin, 1967)和O. beliaevi (Kussakin, 1967)被认为是incertae sedis，直到进一步的形态学和分子数据可以明确它们的分类地位。提供了Oxyarcturus属的地理和水深记录的更新。

Revision of the genus Oxyarcturus (Isopoda, Valvifera, Antarcturidae), with a description of a new deep-sea species from Argentina

A new antarcturid isopod, Oxyarcturus holoacanthus sp. nov. , is fully described based on seven specimens collected in the Mar del Plata submarine canyon at 2950 m depth, during the “Talud Continental III” expedition on board the Argentinian RV “Puerto Deseado”. Oxyarcturus holoacanthus sp. nov. is closely related to O. spinosus (Beddard, 1886), from which it can be distinguished by the body spine pattern. The penial plate, a novel character for the genus Oxyarcturus , as well as for the family Antarcturidae, is described in detail. The species O. dubius (Kussakin, 1967) and O. beliaevi (Kussakin, 1967) are considered as incertae sedis until further morphological and molecular data can clarify their taxonomic position. An update of the geographic and bathymetric records of the genus Oxyarcturus is provided.

期刊介绍： Zoosystematics and Evolution, formerly Mitteilungen aus dem Museum für Naturkunde in Berlin, is an international, open access, peer-reviewed life science journal devoted to whole-organism biology. It publishes original research and review articles in the field of Metazoan taxonomy, biosystematics, evolution, morphology, development and biogeography at all taxonomic levels. The journal''s scope encompasses primary information from collection-related research, taxonomic descriptions and discoveries, revisions, annotated type catalogues, aspects of the history of science, and contributions on new methods and principles of systematics. Articles whose main topic is ecology, functional anatomy, physiology, or ethology are only acceptable when of systematic or evolutionary relevance and perspective.
