from the Caribbean Sea of Colombia is described. The new species resembles morphologically but differs from it principally by its color and habitat. is brown or blueish brown and occurs under intertidal boulders strongly exposed to water movement. is pale brown to beige and lives exclusively in intertidal areas dominated by vermetid snails, exposed to heavy wave action. The entangled tubular shells of vermetids are cemented to each other and to a hard substrate like beach rock, forming a microhabitat for the new crab species and other porcellanids of the genera and . Large genetic distances between DNA sequences of the mitochondrial 16S rDNA gene from and confirmed that they comprise different species. is the 53 member of the West Atlantic porcellanid fauna.
描述了来自哥伦比亚加勒比海的（物种）。新物种在形态上与之相似，但主要在颜色和栖息地方面与之不同。（一种物种）呈棕色或蓝棕色，出现在潮间带巨石下，强烈暴露于水流中。（另一种物种）呈浅棕色至米色，仅生活在以螺旋蜗牛为主的潮间带区域，暴露于强波浪作用下。螺旋蜗牛相互缠绕的管状壳彼此以及与海滩岩石等坚硬基质粘结在一起，为新蟹物种及其他属的瓷蟹属动物形成了一个微生境。来自（两种物种）的线粒体16S rDNA基因的DNA序列之间的大遗传距离证实它们属于不同物种。（新物种）是西大西洋瓷蟹动物群的第53个成员。
