Distribution. Western Atlantic—Brazil (Pernambuco, Sergipe, Bahia, Espírito Santo, Rio de Janeiro, São Paulo, Santa Catarina, Rio Grande do Sul) (Melo 2003; Mossolin & Mantelatto 2008; Souza-Carvalho 2017 unpublished thesis; Souza-Carvalho & Mantelatto 2017).

Remarks. Previous records in São Paulo include Ilhabela (Ilha de São Sebastião) ( Mossolin & Mantelatto 2008). This species is associated with freshwater drainages close to the coast. The phylogeny and taxonomy of the genus is complex and a recenty studies elucidated this scenario ( Souza-Carvalho & Mantelatto 2017). According to these authors it is imperative to make taxonomic rearrangements to solve the non-monophyletic status of T. fluviatilis . Sequences accession number (GenBank): CCDB 1772—16S ( KF688006 ), COI ( KF688054 ) (SouzaCarvalho & Mantelatto 2017).
