Geographic distribution. Punta Piaxtla, Sinaloa, Mexico to Paita, Peru; North Carolina to Gulf of Mexico, Caribbean Sea to Santa Catarina (Perez-Farfante & Kensley 1997)

Previous records. ( Costa et al. 2003)

Distribution in Amapá state. Estuaries of the Sucuriju, Oiapoque and Cassiporé rivers.

Ecological notes. Inhabits muddy or sandy bottoms, from 1 to 70 m deep, abundant in depth up to 30 m. Marine but can enter brackish waters and exceptionally fresh waters ( Cervigon et al. 1992).

Macrobrachium jelskii ( Fig. 4), Palaemon carteri ( Fig. 5), M. amazonicum ( Fig. 3), M. surinamicum ( Fig. 4), M. brasiliense ( Fig. 4) and E. burchelli ( Fig. 1) were the species with greatest geographic distribution in Amapá. Regarding the sampled habitats, the greatest richness of shrimp occurred in rivers and streams, but these also occurred in Amazonas-wells ( Table 3). Considering the habitat types, rivers and streams had high species richness, but streams and estuaries were high in Shannon diversity ( Table 3).
