Pseudopalaemon gouldingi Kensley & Walker, 1982


Pseudopalaemon gouldingi Kensley & Walker, 1982   ( Figs 5D–F, 11)

Identification characters ( Fig. 5D–F). Rostrum short, arched over the eyes, as long as distal margin of scaphocerite; rostral formula: 8–13(2–3 post-orbital teeth)/1–3. Carapace smooth, with antennal and hepatic teeth present, branchiostegal suture indistinct; abdomen smooth, with pleura of second somite enlarged and overlapping pleuron of first and third somites. Telson with posterior margin triangular, ending in a distinct acute point, clearly overreached by inner pair of posterolateral spines. P2 similar in shape and size, chela as long as carpus.

Material examined. 11 females, 1 immat. spec. ( INPA 2320), Bonfim, BR 401 road, igarapé Arraia, tributary of rio Tacutu, 03°21ʹ05ʺ N, 059°54ʹ12ʺ W, 25-XI-1996, colls. V. Py-Daniel et al.

Distribution. Brazil (Amazonas, Roraima [new record]) ( Kensley and Walker, 1982; present study). The distribution in Roraima is depicted in Figure 11.

Remarks. In general, the morphology of our specimens agrees well the description provided by Kensley and Walker (1992). However, the curvature of the rostrum over the eyes ( Fig. 5D) seems to be a little less pronounced in the specimens from Roraima than those from the Negro River basin (see Kensley and Walker 1982: 18, fig. 20)
