Presently, 28 species of pycnogonids are known from the northeastern region of Brazil. This is the largest coastal section of Brazil, with an extent of 3400 km, but the least explored from a scientific point of view. Organic reefs follow the coastal line, becoming concentrated in the section known as the Reef Coast. This section has 17 pycnogonid species recorded. The aim of this paper is to increase our knowledge of the Pycnogonida occurring in northeastern Brazil. Specimens deposited in the Invertebrate Collection Paulo Young, at the Federal University of Paraíba, were examined. As a result, 21 species are identified (18 nominal species and three morphotypes). Eight of these are new records for northeastern Brazil, and one represents a new record for the South Atlantic. Two new species are described: Ammothella calva sp. nov., that has the body short and oval, the proboscis equal to length of body, oval and large, and lateral setae and the eighth, ninth and tenth articles with serrated setae; and Tanystylum parahybanum sp. nov., which has small tubercles on cuticle, eighth article with three long dorsal setae and eighth and ninth articles with one serrated seta.

目前，从巴西的东北地区已知有28种犬龙。这是巴西最大的沿海地区，全长3400公里，但从科学角度出发，探索最少。有机礁石沿着海岸线延伸，集中在所谓的礁石海岸地区。本部分记录了17种食根草属物种。本文的目的是增加我们对巴西东北部发生的毕果目的认识。检查了存放在帕拉伊巴联邦大学无脊椎动物收藏Paulo Young的标本。结果，鉴定出21种（18种名义种和3种形态型）。其中有八项是巴西东北部的新记录，其中一项是南大西洋的新记录。描述了两个新物种：沙门氏菌sp。十一月，具有短而椭圆的身体，长鼻等于身体的长度，椭圆和大，侧面刚毛和具锯齿状刚毛的第八，第九和第十条；和Tanystylum parahybanum sp。十一月，在表皮上有小结节，第八条有三个长背刚毛，第八和第九条有一个锯齿状的刚毛。
