Type locality is 'Balam Canche Cave’ (Grutas de Balankanche, Yucatan). The species is widely distributed within the northern part of the Yucatan Peninsula; it occurs in Quintana Roo, Yucatan, and Campeche.

Remarks.

Despite previous studies stating that T. pearsei has the largest of Typhlatya 's distribution range in the Yucatan Peninsula ( Álvarez et al. 2015), we only collected individuals in a few localities, where it occurred in freshwater, both near the surface in open cenote pools and in deeper cave passages up to 26 m in depth. This species is listed as "least concern" in the IUCN Red List ( De Grave et al. 2013b) and as “threatened” in the Mexican Red List of Threatened Species (NOM-059- SEMARNAT 2010).
