Abstract

We describe two new species of Clathria (Microciona) Bowerbank, 1862: C. (M.) crassitoxa sp. nov. and C. (M.) trairae sp. nov. from Paraíba State (Northeastern Brazil). All are sciophilous species and are represented by small fragments removed from the substrate. Both new species have cleistochelae, and are compared with their cleistocheliferous congeners, differing from all of them by the possession of different combinations of other megascleres and microscleres.

摘要

我们描述了1862年鲍尔班克所定的Clathria（Microciona）属的两个新物种：厚毒Clathria（Microciona）厚毒新种和特拉伊拉Clathria（Microciona）特拉伊拉新种，采自巴西东北部的帕拉伊巴州。所有这些都是喜阴物种，以从基质上取下的小碎片为代表。这两个新物种都有闭螯，并且与它们有闭螯的同属物种进行了比较，它们与所有同属物种的不同之处在于拥有其他大骨针和小骨针的不同组合。
