Rostrum broadly triangular, far overeached by the eyes that are oval. Antennal angle low and blunt, without spine. Antennular peduncle much longer than antennal peduncle, which it overreaches with more than half the length of the last segment. Third maxilliped with merus and ischium strongly widened to form a operculum. Carpus somewhat widened, being less than twice as long as wide; propodus strongly widened, being wider than long; dactylus slender. Large chela of adult male with a deep, but rather wide concavity in the anterior margin of the palm above the fixed finger. Carpus about as long as pal, and as long as high. Merus with a rounded lobe in basal part of lower margin. Surface of larger cheliped with numerous tubercles. Telson distinctly wider than long and much shorter than uropods, being only somewhat more than half as long as endopod. Lateral margins of telson convex, posterolateral corners rounded, posterior margin almost straight, without a spine. Endopod of uropod elongate oval (Ref. 4).
It has a total body length of 7 cm (Ref. 4). It is found from littoral zones to 0.5 m deep, in sheltered bays and estuaries; sandy substrate, in which it digs its burrows; usually with a dense population (Ref. 4).
