Rostrum a low blunt angle of anterior margin of carapace. Eyes triangular, overreaching rostrum with their full length. Antennal spine absent, antennal angle conspicuous and blunt. Peduncles of antennula and of antenna of about same length. Third maxilliped with merus and ischium considerably widened, forming operculum; the last three segments narrow, about twice as long as wide. Laeg chelate of adult male with a distinct concavity in the anterior margin above the base of the fixed finger; in females and young males this concavity is absent or insignificant. Carpus about as long as palm and about as long as high. Merus of adult males with a distinct rounded, forwards produced lobe in basal half of lower margin, upper margin of merus serrate; in females and young males the lobe is much smaller, more triangular, upper margin of merus smooth or indistinctly serrate. Telson longer than wide at base, quadrangular in outline; narrowing slightly posteriorly; posterolateral angles rounded. A small denticle in the middle of the posterior margin, otherwise telson unarmed. Endopod or uropod broadly quadrangular with rounded corners, slightly longer than telson (Ref. 4).
It has body lengths of 1.2 to 6 cm, rarely 7 cm, total body length; 2.5 to at least 5 cm, ovigerous females (Ref. 4). It is found on intertidal mud flats in protected habitats; it makes burrows on soft substrate (Ref. 4).
