The taxonomy and the systematics of the genus are discussed by means of the characterization of its morphological pattern and the first molecular (D2-D3 expansion segments of 28S rDNA) analysis of a representative of this taxon, from Costa Rica. The presence of two or more pairs of male ad-cloacal genital papillae is the most characteristic autapomorphy of the genus, but the status of its species on this concern differ among them. Both morphological and molecular data support a relationship with , which, however, might not be as close as usually assumed. An emended diagnosis of the genus, a key to species identification, and a compendium of their morphometrics are provided. is regarded as , is retained under , and becomes a junior synonym of .
通过对该分类单元形态模式的特征描述以及对来自哥斯达黎加的该分类单元代表进行首次分子（28S rDNA的D2 - D3扩增片段）分析，对该属的分类学和系统学进行了讨论。雄性泄殖腔前生殖乳头有两对或更多对的存在是该属最具特征的自近裔性状，但在这方面其物种的状况各不相同。形态学和分子数据均支持与[另一属名]存在亲缘关系，然而，这种关系可能不像通常认为的那么密切。提供了该属的修订诊断、物种鉴定关键以及它们的形态测量概要。[物种名1]被视为[另一物种名]，[物种名2]保留在[原属名]之下，而[物种名3]成为[另一物种名]的次异名。
