Type locality is Grutas de Balankanche (Yucatan). Widely distributed in the central and northern parts of the Yucatan Peninsula, known from several wells, cenotes and caves of Quintana Roo and Yucatan.

Remarks.

Antromysis cenotensis was present in all the cenotes studied, except for Cenote Cervera. Álvarez et al. (2015) mentions that A. cenotensis occurs mostly above or occasionally below the halocline up to a depth of 16 m. In the present study, the species was only observed in freshwater habitats, in some cases as deep as the scope of the survey. Our findings prove this species as a common representative of the stygofauna of Yucatan, as it was found in more than 95% of the visited sites. Antromysis cenotensis is listed as “threatened” in the Mexican Red List of Threatened Species (NOM-059 SEMARNAT 2010).
