摘要

异足猴(Heterocarpus inopinatus)是熊猫科的成员。它是巴西水域的特有物种，在巴伊亚州、圣埃斯皮里图州和里约热内卢都有记录。本文报道了该物种在巴西最东北部Potiguar盆地的分布情况。波蒂瓜尔盆地位于巴西最东北部，位于塞阿拉州(CE)和北里奥格兰德州(RN)之间(03/05°S;取样是作为“巴西石油公司”赞助的“Avaliacao da Biota Bentonica e plananctonica da Bacia Potiguar e cera (Bpot)”项目的一部分进行的。在150 ~ 982 m的深度，共分析了19条鱼，其中雌鱼10条，雄鱼8条，幼鱼1条。因此，本研究增加了其地理分布，从而大大扩展了该物种在巴西东北部地区较浅深度的深海分布，填补了南大西洋分布的空白。关键词:地理分布;熊猫科;大陆斜坡

OCCURRENCE OF DEEP-SEA SHRIMP Heterocarpus inopinatus TAVARES, 1999 (CRUSTACEA: DECAPODA: CARIDEA) IN POTIGUAR BASIN, NORTHEASTERN BRAZIL

Heterocarpus inopinatus is a member of the family Pandalidae. It is an endemic species from Brazilian’ waters which is recorded for states of Bahia, Espirito Santo and Rio de Janeiro. In this paper, we report the occurrence of this species from extreme northeast of Brazil in Potiguar Basin. The Potiguar Basin is situated in the extreme northeast of Brazil, between the states of Ceara (CE) and Rio Grande do Norte (RN) (03/05° S; 38/35° W). Samplings were conducted as part of the project: "Avaliacao da Biota Bentonica e Planctonica da Bacia Potiguar e Ceara (Bpot)” sponsored by “Petroleo Brasileiro S/A (Petrobras)”. In the campaign were analyzed 19 individuals, being 10 females, 8 males and 1 juvenile, between the depths of 150–982 m. Therefore, this study is increasing its geographic distribution and thus much extending its bathymetric distribution of the species to shallower depth for the Northeast region of Brazil, filling gaps in the South Atlantic distribution. Keywords: Geographic distribution, Pandalidae, continental slope, new record
