Abstract

A new species of caprellid, Deutella mazatlanensis n. sp., is described from Mazatlán Bay, (east Pacific México). Deutella mazatlanensis was found associated with bryozoans, hydroids and sponges in shallow waters. The new species can be differentiated from the remaining species of the genus mainly by the dorsal, anteriorly directed projection on the head; the two dorsal projections and a lateral acute projection anteroventrally projected on pereonite 2 and gnathopod 2 in males. The presence of this species on the Mexican Pacific coast, constitutes the fourth report of Deutella genus for the Pacific Ocean and the first record from the tropical Eastern Pacific.

摘要

一种新的麦秆虫物种，马萨特兰双角麦秆虫（Deutella mazatlanensis n. sp.），是从墨西哥马萨特兰湾（东太平洋）描述的。马萨特兰双角麦秆虫在浅水区与苔藓虫、水螅体和海绵共生。该新物种可主要通过头部背面向前的突出物；雄性第2胸节和第2颚足上向前腹侧突出的两个背侧突出物和一个侧锐突出物，与该属的其他物种区分开来。该物种在墨西哥太平洋海岸的出现，是双角麦秆虫属在太平洋的第四次报告，也是热带东太平洋的首次记录。
