Abstract

Eiconaxius carinatus (Bouvier 1925) is characterized, mostly, by smooth rostral lateral carinae, merus of major chela with smooth dorsal carina, palm of major chela with dorsal carina evident and length of fingers of minor chela less than the palm length. One specimen was collected off the state of Maranhão (00º 08' N and 44º32'W) in a depth of 247 m; this species was known previously from Florida and West Indies (Saint Croix and Saint Vincent), in depths between 161 and 339 m. This record is the first record of this family for Brazil.
