摘要

巴西东北部Potiguar盆地记述一新种Ampelisca milenae sp. nov.。该新种与a . romigi Barnard（1954）相似，但不同之处在于：触角1超过触角2的花梗第5条，尿小体1背隆突起为背弯状突起，末端为尖后臭角，尾足3的内支不远端钩起。新种是在168 ~ 186米深的水域中发现的。提供了从巴西水域记录的所有无足蛇科物种的更新密钥。

A new species of Ampelisca Krøyer, 1842 (Amphipoda, Ampeliscidae) from Potiguar Basin, Brazil.

A new species, Ampelisca milenae sp. nov., is described from Potiguar Basin, Northeastern Brazil. The new species is similar to A. romigi Barnard (1954), however differs from it in having: antenna 1 overreaching peduncular article 5 of antenna 2, urosomite 1 dorsal carina raised into a dorsal sinuous process ending a pointed posterodorsal corner, and inner ramus of uropod 3 not distally uncinate. The new species was collected between 168 and 186 m depth. An updated key to all Ampeliscidae species recorded from Brazilian waters is provided.

期刊介绍： Zootaxa is a peer-reviewed international journal for rapid publication of high quality papers on any aspect of systematic zoology, with a preference for large taxonomic works such as monographs and revisions. Zootaxa considers papers on all animal taxa, both living and fossil, and especially encourages descriptions of new taxa. All types of taxonomic papers are considered, including theories and methods of systematics and phylogeny, taxonomic monographs, revisions and reviews, catalogues/checklists, biographies and bibliographies, identification guides, analysis of characters, phylogenetic relationships and zoogeographical patterns of distribution, descriptions of taxa, and nomenclature. Open access publishing option is strongly encouraged for authors with research grants and other funds. For those without grants/funds, all accepted manuscripts will be published but access is secured for subscribers only.
