Petalidium suspiriosum Burkenroad, 1937: 325 , figs. 8–12. — Ebeling et al. 1969:12. — Walters 1976: 824. — Word & Charwat 1976: 27. — Krygier & Pearcy 1981: 76. — Hendrickx & Estrada-Navarrete 1989: 110; 1996: 75, fig. 47. — Pérez Farfante & Kensley 1997: 193. — Wicksten 2002: 131.

Diagnosis. Rostrum short, with 1 or 2 terminal teeth, rising abruptly from plane of carapace. Carapace with hepatic spine, points at antennal, branchiostegal, pterygostomian angles; strong carina running posteriorly from eyestalk toward posterior margin; cervical, gastro-cardiac grooves present. Eye pigmented. First segment of antennular peduncle concave, male with hooked antennular flagellum. Scaphocerite with blade exceeding blunt spine. Antennal flagellum long. Second maxilliped with strong, dense, dark setae along margin of last two segments. Third maxilliped and pereopods with very long setae. Abdominal somite 6 ending in terminal point, another point on ventrolateral margin. Telson with pair lateral points near acute apex. Outer uropod without setae on outer margin. Total length 38 mm.

Color in life. Red to purplish red; black pigment fleck present in dorsal view on ocular segment between eye.

Habitat and depth. Pelagic, 150–1750 m, maximum population density off Oregon at 600–1000 m . Walters (1976) reported that off the Hawaiian Is. this species was non-migratory and usually lived below 800 m.

Range. Hawaiian Is., northwestern Pacific Ocean, Oregon to Clarion I., Mexico. Type locality north of Clarion I.: 20 ˚ 36' N, 115 ˚ 07' W.

Remarks. This may be the species reported as " Sergestes sp. indet." by Rathbun (1904) and Schmitt (1921).
