Distribution. Nicaragua, Trinidad, Venezuela, Guyana, Suriname, French Guiana, Colombia, Brazil (Roraima, Amazonas) (Magalhães, 2003; Magalhães and Türkay, 2008; Campos, 2005; 2014; Pereira and García, 2006; this study).

Remarks. With respect to the carapace morphology, P.dentata highly resembles M. laevifrons . However, both species can be readily distinguished by the spined (in P. dentata ) or smooth ( M. laevifrons ) frontal margin. The morphology of the G1 of the specimens studied herein ( Fig. 2B View Figure 2 ) is very similar to the description and illustrations offered by Magalhães and Türkay (2008). Poppiana dentata has a very wide distribution in northern South America, occurring in the Orinoco River basin and in several coastal river basins from French Guiana to Colombia, as well as on the island of Trinidad and in Nicaragua ( Campos, 2005; 2014; Magalhães and Türkay, 2008). The distribution of the species in the Amazon River basin seems to be restricted to the Branco River basin, in Roraima ( Fig. 5 View Figure 5 ), and the upper Negro River basin, in Amazonas ( Magalhães and Türkay, 2008; this study).
