Diagnosis. Rostrum acute, apices of postorbital spines pointing anteriorly, upper margin of orbit prominent but without supraocular spine. Basal antennal article with outer margin prolonged into slightly incurved spine. Carapace broadly triangular, pear-shaped, convex; surface granulate, tuberculate, with fine pubescence, especially in small individuals. Male chelipeds short, stout, granulate; chela inflated, fingers nearly as long as palm, gaping at base; female chelipeds more slender, margins of hand parallel, fingers slightly gaping. Pereopods 2–5 slender, similar, diminishing in length from anterior to posterior, dactyls moderately curved, almost smooth. Male carapace length 15.7 mm, carapace width 12.3 mm, female not reported.

Color in life. Dull green-brown, ventral surface dirty white. The color notes are from a crab from Princeton Harbor, San Mateo County, California .

Habitat and depth. Pilings, sandy bottoms, sand, shell, among seaweeds, extreme low intertidal zone to 415 m.

Range. Tomales Bay, California to Cape Corrientes, western Colombia. Introduced into Japan, New Zealand, and Australia ( Lemaitre et al. 2001). Type locality mouth of San Diego Bay , California .

Remarks. Pyromaia tuberculata may be found almost devoid of a covering or may be densely covered by small bits of algae. The crab can move with great agility on sand. Small ones may associate with the sea star Pisaster brevispinus (Stimpson, 1857) . Garth (1958) recognized two subspecies, P. tuberculata mexicana and P. tuberculata tuberculata . The typical subspecies is the one present in the area of coverage. Hendrickx (1990: 79) considered that this division was unjustified.
