Distribution. Brazil (Pernambuco, Alagoas, Sergipe, Bahia, Minas Gerais, Espírito Santo, Rio de Janeiro, São Paulo, Paraná, Santa Catarina, and Rio Grande do Sul)

Previous records in Minas Gerais. Magalhães 1991; Gomides et al. 2009; Souza-Carvalho et al. 2017; Carvalho et al. 2018. USNM 1254072, Córrego da Cachoeira, São Francisco.

Remarks. The revisionary study using morphological and molecular data by Souza-Carvalho et al. (2017) revealed that the taxonomic entity currently morphologically recognized as Trichodactylus fluviatilis is a complex of several species, that are currently under study (Souza-Carvalho et al. unpubl.). Thus, the specimens found in the hydrographic basins of Minas Gerais are tentatively treated here as T. fluviatilis .
