Until now, was considered a monospecific leptocheliid genus, with the species considered a taxon with a wide distribution, from the Northwestern Atlantic to the Mexican Caribbean. Herein, after a detailed revision of type and topotype materials and specimens collected from the Mexican Caribbean, a new species sp. nov. is described, and the redescription of is provided. Also, we found a significant genetic divergence between the two species based on the nucleotide sequences of cytochrome oxidase subunit I, which support the morphological data. The morphological features used to recognize both species are also adequate to link males, females, and juvenile stages, although these species have a high intraspecific polymorphism.
直到现在, 被认为是一个单种的细螯蟹属,其物种 被认为是一个分布广泛的分类单元,从西北大西洋到墨西哥加勒比地区。在此,在对模式标本、原产地模式标本以及从墨西哥加勒比地区采集的标本进行详细修订之后,描述了一个新物种 sp. nov.,并对 进行了重新描述。此外,基于细胞色素氧化酶亚基I的核苷酸序列,我们发现这两个物种之间存在显著的遗传差异,这支持了形态学数据。用于识别这两个物种的形态特征也足以将雄性、雌性和幼体阶段联系起来,尽管这些物种具有高度的种内多态性。
