Rathbun, 1896 (Crustacea: Decapoda: Portunidae) is firstly recorded from the state of Sergipe, NE Brazil, filling a gap in the species distribution along Brazilian coast.

The blue crab Callinectes sapidus Rathbun, 1896 is an ° - ° - River, state of Sergipe, northeastern Brazil (10 45’58”S;- important fishery; resource at several places along the At 37 09’14”W) (Figure 1b). At this place, the water salinity lantic coast of America (Williams 1974; Milliken and Wil rangedi.e. from 2 to 7 and the sediment was composed main liams 1984 Stagg and Whilden 1997). Native from western ly by poorly sorted fine sand with 13-27% of fine fractions Atlantic, this species has been also recorded in the eastern ( , silt plus clay) and organic matter content around 2%.
