Distribution in Neotropics. Mexico, Panama.

Note. So far known from a single male recorded from a fast-flowing lowland river with stony and sandy substratum in Mexico (Kyerematen & Andersen 2002). Adult males are photophilous - both Mexican and Panamanian specimens were mostly sampled using light traps, at rivers and streams. Probably one of the most common Rheotanytarsus species in Panama.
