Rostrum ending in 3 teeth, the median long with a rounded apex ending in two spines; lateral teeth short, much shorter than half the median tooth, and separated from it by a deep groove. The median groove of the median tooth shallow. No spines on ventral surface of the rostrum. Anterolateral margin of the carapace with a small but distinct tooth at the level of the eye. First pereiopods subchelate. In the adult male the palm is distinctly widened at the base of the fixed finger, so that the height of the chela is only slightly less than the length. Movable finger with blunt tubercles on the cutting edge, but otherwise without tubercles, spines or ridges. Palm with 2 dorsal rows of spinules. Merus with a subdistal anterodorsal spine (Ref. 4).
It has a total body length of 4 to 6.5 cm (Ref. 4). It is found in intertidal and subtidal zones down to about 45 m, sometimes in estuarine areas. It makes simple Y-shaped burrows with 2 or more entrances in the mud or sandy mud (Ref. 4). Members of the order Decapoda are mostly gonochoric. Mating behavior: Precopulatory courtship ritual is common (through olfactory and tactile cues); usually indirect sperm transfer (Ref. 833).
