Previous distribution.

Creaser 1936, 1938; Nicholas 1962; Reddell 1977, 1981; Holsinger 1990; Iliffe 1992, 1993; Fiers et al. 1996; Rocha et al. 1998; Botosaneanu & Iliffe 1999, 2002; Álvarez et al. 2005; Iliffe & Botosaenau 2006; Álvarez and Iliffe 2008; Sánchez-Rodríguez 2008; Ruiz-Cancino et al. 2013; Álvarez et al. 2015; Ortiz and Chazaro-Olvera 2015; Benítez et al. 2019.

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 Álvarez et al. (2015) as a freshwater species. However, as Benítez 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).
