Rostrum triangular, depressed, unarmed, usually not reaching distal margin of cornea. Carapace smooth, antennal tooth present; abdomen smooth, pleura of second somite enlarged and overlapping pleuron of first and third somites. Telson with posterior margin convex, its posterolateral angles with 2 pair of spines, inner pair distinctly larger than outer one. P2 (second pair of chelipeds) similar in shape, not in size; both merus and carpus without subterminal spines on inner distal margin. Male Plp2 with endopod longer than exopod; endopod bearing 2 rows of setae on inner margin distally to reduced appendix interna. <b>Material examined.</b> 10 males, 19 females (3 ovig.), 18 immat. spec. (INPA 2328), Bonfim, vicinal Tucano, unnamed igarapé, tributary of rio Tacutu, 03°25ʹ25.3ʺ N, 060°03ʹ44.1ʺ W, 26-II-20015, colls. M.A.L. Santos, I. R.S. Almeida, S.C. Emídio and F.C. Zanetti; 1 male, 3 females (INPA 2393), Bonfim, vicinal do Tucano, unnamed igarapé, tributary of rio Tacutu, 03°25ʹ25.3ʺ N, 060°03ʹ44.1ʺ W, 27-II-2015, colls. M.A.L. Santos, I. R.S. Almeida, S.C.

Santos. <b>Distribution.</b> Guyana, Suriname, French Guiana, Brazil (Amazonas, Pará, Roraima [new record]), (see Pimentel and Magalhães 2014 for references; present study).

No significative intraspecific variability was noticed.
