Previous distribution.

Hobbs and Hobbs 1976; Hobbs et al. 1977; Hobbs 1979; Reddell 1977, 1981; Iliffe 1992; Rocha et al. 1998; Webb 2003; Botello and Álvarez 2013; Benítez 2014; Álvarez et al. 2015; Chávez Solís 2015; Benítez et al. 2019.

Type locality is Cenote Kabahchen (Yucatan). The species occurs in numerous caves and cenotes throughout the peninsula in Quintana Roo and Yucatan.

Remarks.

Our findings corroborate that T. mitchelli is a widespread common crustacean in the freshwater cenotes of Yucatan. This species was caught from the shallow zones to 34 m in depth, indicating a wide vertical range as well as a wide geographical range. The species was also observed (but not collected) in cenotes Yaal Utsil, Santito, Pol Box, Kankal, San Elias, Dzonotila, X’baba, X’kokob, Pixton, Dzalbay, and Yax-Kis. Typhlatya mitchelli is listed as "least concern" in the IUCN Red List ( De Grave et al. 2013a) and as “threatened” in the Mexican Red List of Threatened Species (NOM-059- SEMARNAT 2010).
