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).
