Abstract

Caprellid material of the present study was collected between 25-3000 m depth from the Campos Basin area, Southwestern Atlantic. As a result, Deutella incerta was found as a new record to the Southwestern Atlantic and two new species are described: Liropus guerragarciai sp. nov. and Mayerella sittropiae sp. nov. Besides, Paracaprella pusilla is herein redescribed as a common component of the Campos Basin amphipod community. Caprellids are a diverse and abundant group that can be found among algae and general biological substrates of the continental shelf area. As more deep sea samples are coming into light, they are turning out to be also a common component in this habitat. Including the present data, there are 25 caprellid species recorded in Brazil, being four of them restricted to the slope areas and 14 endemic to the Brazilian coast. A key to the Caprellidae species from Brazil is provided.

摘要

本研究中的麦秆虫材料是在西南大西洋坎波斯盆地海域25 - 3000米深度之间采集的。结果发现，不确定双螯麦秆虫（Deutella incerta）是西南大西洋的新记录物种，并描述了两个新物种：格拉西亚氏细螯麦秆虫（Liropus guerragarciai sp. nov.）和西特罗皮亚梅氏麦秆虫（Mayerella sittropiae sp. nov.）。此外，本文重新描述了微小副麦秆虫（Paracaprella pusilla），它是坎波斯盆地端足类群落的常见组成部分。麦秆虫是一个种类多样且数量丰富的类群，在大陆架区域的藻类和一般生物基质中都能找到。随着越来越多的深海样本被发现，它们也成为了这个栖息地的常见组成部分。包括目前的数据在内，巴西已记录有25种麦秆虫，其中4种仅分布于斜坡区域，14种为巴西海岸特有种。本文还提供了巴西麦秆虫科物种的检索表。
