Macrobrachium nattereri (Heller, 1862) View in CoL ( Figs 4A–D, 10)

Previous records. Ramos-Porto and Coelho (1998, in list); Melo (2003, in list); Castro and Silva (2013).

Identification characters ( Fig. 4A–D). Rostrum straight, short, slightly directed downwards, reaching distal margin of scaphocerite; rostral formula: 8–11(2–3 post-orbital teeth)/1–4. Carapace with antennal and

hepatic spines present, anterolateral portion roughened by numerous spinules; abdomen also roughened by spinules, pleurae of second somite enlarged and overlapping pleuron of first and third somites. Telson with posterior margin distinct, ending in a small acute point, usually overreached by inner pair of posterolateral spines. P2 (larger cheliped) similar in shape, unequal in size; larger cheliped overreaching scaphocerite with large part of the length of carpus, palm pear-shaped in cross-section with distinct longitudinal sulcus on outer surface, fingers approximately 0.6 times the length of palm, with row of tubercles on cutting edges.

Distribution. Venezuela, Colombia, French Guiana, Brazil (Amazonas, Amapá, Bahia, Ceará, Pará, Roraima), Peru (see Pimentel and Magalhães 2014 for references; present study). The distribution in Roraima is depicted in Figure 10.

Remarks. The morphology of our specimens agrees very well with the description provided by Holthuis (1952). Macrobrachium nattereri closely resembles M. brasiliense and M. ferreirai , and their juveniles and subadult specimens are very difficult to distinguish (Kensley and Walker 1992).

Ramos-Porto and Coelho (1998) and Melo (2003) listed M. nattereri as occurring in the state of Roraima, but without specifying the localities. The records presented here confirm its occurrence in Roraima ( Fig. 10).
