Mantelatto et al., 25.xi.2008; 1 ♂, CCDB 2665, Ubatuba, Tavares river BR101 - Km 11.5, colls. E. Mossolin & F. Mantelatto, 17.ix.2008; 1 ♂, 1 ♀, CCDB 2077, Ilhabela, Praia do Portinho, coll. E. Mossolin, 17.vii.2006; 2 j, CCDB 3295, Ilhabela, Castelhano river, colls. F. Mantelatto et al., 21.ii.2011; 14 ♂, 6 ♀, 1 j, CCDB 1775, river next to Praia da Trincheira, Ilha Comprida, Cananéia, colls. F. Mantelatto et al., 30.viii.2011; 1 ♂, 2 ♀, CCDB 3187, river next to Praia da Trincheira, Ilha Comprida, Cananéia, colls. F. Mantelatto et al., 17.iv.2011; 5 ♂, 4 ♀, 23 j, CCDB 3792, river next to Praia da Trincheira, Ilha Comprida, Cananéia, colls. F. Mantelatto et al., 11.iii.2012.

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(Rio de Janeiro, São Paulo, Paraná, Santa Catarina) (Melo 2003; Mossolin & Mantelatto 2008; Souza-Carvalho 2017 unpublished thesis).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