Moderate-sized spider crab with a pear-shaped body and orange chelipeds with blue trim. Two related species differ in having the second last segment of the legs expanded terminally to form a claw and in having large spines (Naxia spinosa) and tubercles (Naxia tumida) on the upper surface of the carapace. All three species occur in sheltered vegetated habitats along the southern coast, with N.aurita the most common.
