ABSTRACT

New data on the taxonomic composition and distribution of rare deep-sea species of the Bathylagidae, Microstomatidae, and Opisthoproctidae (Argentiniformes) collected off northeastern Brazil, including the Rocas Atoll, the Fernando de Noronha Archipelago, and seamounts off Rio Grande do Norte State are provided. Collections were made by the French RV Antea during the ABRACOS 2 (Acoustics along the BRAzilian COaSt) expedition, between April 9 and May 6, 2017. Among the six species of argentiniforms identified, three are reported for the first time in Brazilian waters: Xenophthalmichthys danae (Microstomatidae), Opisthoproctus soleatus and Rhynchohyalus natalensis (Opisthoproctidae). Three additional species previously recorded off Brazil have their geographic distributions extended to the northeastern region of the country: Dolicholagus longirostris, Melanolagus bericoides (Bathylagidae), and Winteria telescopa (Opisthoproctidae). Remarks on other species of the Argentiniformes reported in the Brazilian Exclusive Economic Zone are also provided. A total of 11 genera and 14 species of the order are confirmed to occur in the region.

摘要

关于巴西东北部包括罗卡斯环礁，费尔南多·德诺罗尼亚群岛和北里奥格兰德州海山的罕见的深海物种，如y科，小口科和Op科（阿根廷龙门科）的分类学组成和分布的新数据是假如。法国RV Antea在2017年4月9日至5月6日的ABRACOS 2（巴西海岸声学）远征期间采集了这些。在发现的六种阿根廷形态中，有三种首次在巴西水域报告：Xenophthalmichthys达娜厄（Microstomatidae），后肛鱼和Rhynchohyalus纳塔尔（蛇形目科）。先前记录在巴西三个附加物种具有其地理分布扩展到该国的东北地区：大吻长兔鲑，Melanolagus bericoides（Bathylagidae）和望远冬肛鱼（Opisthoproctidae）。还提供了在巴西专属经济区报道的其他阿根廷象形目的评论。确认该地区总共有11属和14种该物种。
