Carapace grows to approximately 2 cm in length. P. hirsutiusculus, abundant in the mid zone, has white bands on walking legs, dark antennae with fine white bands, and a dark orange-brown body. P. samuelis is the most abundant hermit crab in the high zone of central and southern California. It has a hairy carapace and legs, blue bands on walking legs, and red antennae.
