Distribution. Western Atlantic—Brazil (Rio de Janeiro, São Paulo, Paraná, Santa Catarina) (Melo 2003; Mossolin & Mantelatto 2008; Souza-Carvalho 2017 unpublished thesis).

Remarks. Previous records in São Paulo include Ilhabela (Ilha de São Sebastião) ( Mossolin & Mantelatto 2008). Eventhough it is a group of primary crabs, this species is associated with freshwater drainages close to the coast. The phylogeny and taxonomy of the genus is complex and a recent study elucidated this scenario (Souza-Carvalho & Mantelatto 2017). Sequences accession number (GenBank): CCDB 1775—16S ( KF688016 ), CCDB 3187—COI ( KF688059 ) ( Souza-Carvalho & Mantelatto 2017).
