Distribution. Guyana, Suriname, French Guyana, Brazil (Amapá, Amazonas, Pará, Roraima) ( Holthuis, 1959; 1993; Rodriguez, 1982; Magalhães, 1986; 2003; Vieira, 2008; this study).

Remarks. The G1s of the specimens studied herein from the Tacutu River ( Fig. 1H View Figure 1 ) exhibit an overall resemblance with the G1 of the specimen from the Surumu River figured by Magalhães (1986: 629, fig. 8). However, some of the specimens from the Jatapu River basin, in southeastern Roraima have a G1 with more longitudinally straight apical plate, resembling those from the Uatumã River basin ( Magalhães, 1986: 629, figs. 9, 10).

The species has a broad distribution that includes several rivers draining both slopes of the Guyana Shield in Brazil (east from the Branco River basin in Roraima to the western portion of the state of Amapá), Guyana, Suriname and French Guiana ( Holthuis, 1959; 1993; Rodriguez, 1982; Magalhães, 1986; 2003; Vieira, 2008; this study). The species is typically found in the upper course of the rivers, usually inhabiting fast flowing, lotic waters with rocky bottoms of rapids and falls ( Magalhães, 1986, 2003; Holthuis, 1993).
