Eualus macrophthalmus . — Holthuis 1947: 11. — Kozloff 1974: 166. — Word & Charwat 1976: 105. — Butler 1980: 189, pl. 8A. — Wicksten 1989b: 312; 1990b: 593; 2002: 137. — Chace 1997: 43. — Jensen 2004: 468. Diagnosis. Rostrum deep, reaching beyond antennular peduncle, with 10–14 dorsal, 1–4 ventral teeth, apex acute. Second and third segments of antennular peduncle with terminal spines, stylocerite not reaching end of first segment. Carapace with pterygostomian tooth minute or absent. Pereopod 1 moderately large, pereopod 2 slender. Pereopods 3–5 long, slender, with slender, simple dactyls. Merus of pereopod 3, with 5 or 6 spines; pereopod 4, with 5 or 6 spines; pereopod 5, with 4 spines. Pleura of abdominal somites 1–4 rounded, 5 with ventral point. Telson with 5 or 6 pairs dorsolateral spines. Male total length to 43 mm, female to 71 mm. Color in life . Pale yellow with red speckling (Butler 1980). Habitat and depth. The species may be pelagic (Butler 1980), 110–1163 m.. Range. Unalaska to Point Sur, California. Type locality off Tawit Head, Washington. Word & Charwat (1976) erroneously reported it from Tanner Bank. The specimen in question was collected with a "Tanner trawl" off Monterey County, California. : Published as part of Wicksten, Mary K., 2012, Decapod Crustacea of the Californian and Oregonian Zoogeographic Provinces 3371, pp. 1-307 in Zootaxa 3371 on page 78 : {"references": ["Rathbun, M.
