| Abstract |
A new species of Remipedia (Crustacea) is described from a recently discovered section of the anchialine cave system Cenote Crustacea, situated on the northeastern coast of the Yucatán Peninsula. Speleonectes fuchscockburni n. sp. is thesecond remipede species from the Caribbean coast of Mexico. Adult specimens are relatively small and slender, with bodylengths between 12 and 16 mm, and up to 35 trunk segments. The new species can be distinguished morphologically from S. tulumensis by sparsely setose appendages, a ventral antennular flagellum composed of 5–6 segments, and 10–12 deeplyincised denticles of the terminal maxillary and maxillpedal claws. The status of Speleonectes fuchscockburni as a new spe-cies is validated by a comparison of cytochrome c oxidase subunit I (COI) sequences from selected remipede taxa, including Speleonectes tulumensis. The uniquely high abundance of S. tulumensis in Cenote Crustacea and the distribution of the two remipedes in this cave are discussed in relation to hydrology and cave morphology. |
