Eupagurus setosus Benedict, 1892a: 19 View in CoL .

Pagurus setosus View in CoL . — Rathbun 1904: 159, pl. 5, fig. 1. — Schmitt 1921: 136, fig. 58. — McLaughlin 1974: 110, figs. 27–29. — Lemaitre & Castaño 2004: 79.

Diagnosis. Rostrum rounded, slightly longer than lateral projections of carapace. Eyestalk elongate, cornea not dilated, ocular scale pointed. Major cheliped with carpus, chela proper sharply spinose, chela proper setose, bearing 7 longitudinal rows of spines. Minor cheliped setose, carpus, chela also bearing spines. Pereopods 2, 3 with elongate dactyls, series of spines on carpus of anterior pair only, both pairs with scattered setae. Telson with left lobe slightly larger than right, with V-shaped median cleft; right terminal margin with 4–8 small teeth, 1 stronger laterodistal tooth; left with 4–9 small teeth, one larger laterodistal tooth. Carapace length to 21 mm.

Color in life. Not reported. Rathbun (1904) noted that pereopods 2, 3 were banded.

Habitat and depth. Mud or sand, 9–476 m.

Range. Kodiak, Alaska to off Santa Cruz I., California. Type locality Sitka, Alaska .

Remarks. A small and common hermit crab of the continental shelf off southern California has been identified as P. setosus ( Wicksten 1980c: 361) . This identification needs confirmation.
