Abstract


Typhlatya is a genus of small, stygobitic shrimp in the family Atyidae. Phylogenic relationship of a new population of Typhlatya discovered from Cenote Xtabay of the Ponderosa system, in Quintana Roo, is examined using H3 sequences. Results suggest that either it is a very closely related sister species to T. dzilamensis, with T. dzilamensis probably inhabiting the northern seacoast of Yucatan, and the new and undescribed species inhabiting the eastern seacoast. Alternatively, they are a single species with high morphologic variability, whose habitat encompasses the whole coastline of Yucatan.
