Abstract

A new species of the genus Paracaprella is described based on the specimens associated with the algae Sargassum cymosum and Laurencia obtusa that were collected from infralittoral depths (0.5 to 3.0 m) at Sepultura Beach, Bombinhas and Paciência Beach, Penha, Santa Catarina State, Brazil. This new species differs from the others of the genus by the unique morphology of the males' gnathopod 2: its propodus has a grasping margin provided with a deep groove. An identification key for Paracaprella species is also presented.

摘要

基于从巴西圣卡塔琳娜州彭哈市博米尼亚斯的塞普尔图拉海滩和帕西ência海滩潮下带深度（0.5至3.0米）采集的与藻状马尾藻和钝形凹顶藻相关的标本，描述了副鳃尾钩虾属的一个新物种。该新物种与该属其他物种的不同之处在于雄性第二颚足独特的形态：其掌节有一个带有深槽的抓握边缘。还给出了副鳃尾钩虾属物种的鉴定检索表。
