Type locality is Cenote Sambula (Motul, Yucatan). Known from numerous caves and cenotes in Quintana Roo and Yucatan, and a well in Campeche. Remarks. The species was also observed in cenotes Yaal Utsil, Pol Box, X'kokob , Bebelchen, Kankal, San Elias, Dzonotila, Yax-Kis, Xaan and X'baba . Creaseriella anops was found both in cavern and cave sections, between 3 and 40 m deep. Our observations generally agree with the records of Iliffe and Botosanenau (2006) and Alvarez et al. (2015) as a freshwater species. However, as Benitez et al. (2019) reported, we also observed individuals around or below the halocline. Creaseriella anops is listed as "threatened" in the Mexican Red List of Threatened Species (NOM-059- SEMARNAT 2010 ). Figure 3.
