Material examined. None

Disgnosis. Shield slightly longer than broad. Rostrum triangular with rounded tip. Ocular peduncles slender, dilated distally, 3/4 length of shield; ocular scales widely separate, broad at base, distal half thin, with 2 or 3 terminal spines. Chelipeds equal or the left slightly stronger; fingers with same length of carpus; proximal half of fixed finger with 4 acute corneous teeth; mesial face of carpus with 5 long corneous teeth; merus with spiny teeth on anterior margin. Ambulatory legs slender; dactylus with spinules on dorsal face of proximal half, spinose setae on ventral face of distal half; dorsal face of propodus with 8 spines; dorsal face of carpus with 9 acute spines. First pleopod in the males with inferior lamella narrow; distal region spatulate, bordered by row of strong recurved teeth. Distal lobe broad, rounded tip, broader then inferior lamella; inner lobe short, with long setae on ventral face.

Distribution. Western Atlantic—Brazil (Rio de Janeiro) and Uruguay.

Remarks. Rahayu (2005), when examining some species belonging to the genus Paguristes , noticed that some species have 12 pairs of gills, despite 13 pairs being the characteristic number for the genus Paguristes . Thus, Rahayu (2005) transferred those species with 12 pairs of gills to the genus Stratiotes Thomson, 1899 . However, Stratiotes Thomson, 1899 , is a junior homonym of Stratiotes Putzeys, 1846 (Coleoptera) . Therefore, Stratiotes was replaced by Areopaguristes (see Rahayu & McLaughlin, 2010; McLaughlin et al., 2010).
