Distribution. Venezuela, Suriname, Ecuador, Peru, Colombia, Brazil (Acre, Amazonas, Maranhão, Pará, Rondônia, Roraima), Bolívia (Holthuis, 1959; Rodríguez, 1992; Magalhães, 2002; 2003; 2005; Vieira, 2008; Castro and Silva, 2013; Campos, 2014; this study).
Remarks. The taxonomic status of V. serrata and related forms (Magalhães and Türkay, 1996a) is not yet settled due to a considerable amount of variability found either in somatic or gonopodal characters (C. Magalhães, unpubl. data). Most of the male specimens studied herein are immature or subadults. As such, the gonopod morphology could not be adequately evaluated. However, in the few fully-grown adults examined, the G1 shows the distal portin moderately curved (approximately 40–45°) in ventro-lateral direction, with its margins nearly subparallel; the subterminal field of spines is well developed and the ventral border has a distinct subretangular, median lobe (Fig. 2D).
The present species has a very broad distribution throughout the entire Amazon River and Orinoco River basins as well as in the coastal river basins of northern South America, but has only recently been reported in the state of Roraima (Castro and Silva, 2013). The above records show that it is also well distributed in the state, occurring mainly in the lowland portion of the Branco River, Jauaperi River and Jatapu River basins (Fig. 7).
