Venezuela, Guyana, and Brazil [new record] (Roraima) (Rodriguez, 1982; this study). Remarks. The G 1 s of our specimens (Fig. 1 A) are morphological very similar to that of a specimen from the Rupununi River, in Guyana, figured by Rodriguez (1982: 135, fig. 129). Until now, the species was known from eastern Venezuela and Guyana in the Essequibo River and Demerara River basins (Rodriguez, 1982). Its occurrence in the Uraricoera River basin indicates that the species can be found in both the northern and southern slopes of the Guyana Shield (Fig. 3).	en	Magalhães, Francinéia Zanetti Patrícia Macedo de Castro Célio (2018): Freshwater crabs (Decapoda: Brachyura: Pseudothelphusidae, Trichodactylidae) from the state of Roraima, Brazil: species composition, distribution and new records.

L. S. Aquino and U. C. Barbosa. Distribution. Venezuela and Brazil (Roraima) (Rodriguez and Pereira, 1992; Magalhães et al., 2014). Remarks. Rodriguez and Pereira (1992) described a new subspecies, F. estevisi siapensis Rodríguez and Pereira, 1992, and distinguished it from the nominal subspecies by the mesial lobe of the G 1, presenting “ the proximal margin concave and the distal margin regularly arched ”, giving it a thumb-like appearance, whereas the nominal subspecies has a mesial lobe with proximal and distal margins more or less straight, showing a conical shape. The specimens from Roraima have a G 1 with mesial lobe bearing a conical appearance (Fig. 1 B, C) and are therefore assigned to the nominal species. Besides, the localities of the Roraima specimens (particularly those of the Miang River) (Fig. 3) are not geographically distant from the localities in the upper Caroni River presented by Rodriguez and Pereira (1992). According to these authors, the nominal form is distributed in the southeastern portion of the state of Bolívar, in the “ Gran Sabana ” region, mainly in tributaries of the upper Caroni River coming from the slopes of Mount Roraima and draining to the Orinoco River Basin, while F. estevisi siapensis occurs in the Siapa and Cunucunuma Rivers, in the Venezuelan state of Amazonas.	en	Magalhães, Francinéia Zanetti Patrícia Macedo de Castro Célio (2018): Freshwater crabs (Decapoda: Brachyura: Pseudothelphusidae, Trichodactylidae) from the state of Roraima, Brazil: species composition, distribution and new records.

Venezuela, Brazil (Roraima) (Rodríguez and Suárez, 1994; Mora-Day and Blanco-Belmonte, 2008; this study). Remarks. The gonopods of the specimens from Roraima (Fig. 1 G) show a high morphological similarity with that of the holotype as described in Rodríguez and Suárez (1994) and figured in Rodríguez and Campos (1998: 766, fig. 2 A, B) and no remarkable variation was noticed. With the present records, F. stenolobus exhibits a somewhat wide distribution that encompasses both the Amazonian and Orinocoan slopes of the Serra Paracarima. On the Venezuelan side, the species is distributed in the contiguous hydrographic basins of the Caura River (Rodríguez and Suárez, 1994; Magalhães and Pereira, 2003) and in the Paragua River (Mora-Day and Blanco-Belmonte, 2008). On the Brazilian side, it seems to be relatively frequent in the more elevated areas (above 750 m) of the upper Uraricoera River and upper Surumu River basins, but also occurring at lower elevations in the middle course of the Branco River after its confluence with the Mucajaí River (lower than 100 m) (Fig. 4).	en	Magalhães, Francinéia Zanetti Patrícia Macedo de Castro Célio (2018): Freshwater crabs (Decapoda: Brachyura: Pseudothelphusidae, Trichodactylidae) from the state of Roraima, Brazil: species composition, distribution and new records.

The G 1 s of the specimens studied herein from the Tacutu River (Fig. 1 H) exhibit an overall resemblance with the G 1 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 G 1 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).	en	Magalhães, Francinéia Zanetti Patrícia Macedo de Castro Célio (2018): Freshwater crabs (Decapoda: Brachyura: Pseudothelphusidae, Trichodactylidae) from the state of Roraima, Brazil: species composition, distribution and new records.

Venezuela, Colombia, Brazil (Amazonas, Roraima [new record]) (Magalhães, 2003; Campos, 2002; 2005; 2014; this study). Remarks. This species is easily recognized by the orbicular carapace with lateral margins bearing 7 - 8 acute teeth and frontal margin bilobed, smooth. The G 1 is slender, distally straight and regularly tapering. The apex is narrow and assymetrical, with its mesiodistal border being slightly shorter than the latero-distal border (Fig. 2 A). The species is mainly distributed in the Amazon River and Orinoco River basins in Brazil, Colombia, and Venezuela (Magalhães, 2003; Campos, 2002; 2005; 2014). In the Brazilian territory, it was only known in the state of Amazonas, in the Negro River basin (Magalhães, 2003). The above records show that it also occurs in the Branco River basin and constitute the first report of the species in the state of Roraima (Fig. 5).	en	Magalhães, Francinéia Zanetti Patrícia Macedo de Castro Célio (2018): Freshwater crabs (Decapoda: Brachyura: Pseudothelphusidae, Trichodactylidae) from the state of Roraima, Brazil: species composition, distribution and new records.

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 G 1 of the specimens studied herein (Fig. 2 B) 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), and the upper Negro River basin, in Amazonas (Magalhães and Türkay, 2008; this study).	en	Magalhães, Francinéia Zanetti Patrícia Macedo de Castro Célio (2018): Freshwater crabs (Decapoda: Brachyura: Pseudothelphusidae, Trichodactylidae) from the state of Roraima, Brazil: species composition, distribution and new records.

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, 1996 a) 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 G 1 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. 2 D). 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).	en	Magalhães, Francinéia Zanetti Patrícia Macedo de Castro Célio (2018): Freshwater crabs (Decapoda: Brachyura: Pseudothelphusidae, Trichodactylidae) from the state of Roraima, Brazil: species composition, distribution and new records.
