Short description
Morfología | Morfometría
Radios blandos dorsales (total): 70-77; Radios blandos anales: 55 - 63; Vértebra: 42 - 44. This species is distinguished by the following: Vertebrae (11-) 12+ 30-32=42-44, dorsal fin rays 70-77, anal fin rays 55-63; eyes that are moderately large (2.4-3.0% SL), D/V 6-7; outer pseudoclasper large, twice the length of the inner pseudoclasper, wing-shaped, with narrow base, flat and its posterior part strongly bent backward; inner pseudoclasper almost completely joined to outer pseudoclasper anteriorly, thin, small, with single tip, not extending over anterior part of outer pseudoclasper; narrow scale patch on cheek with 3-5 scale rows on upper cheek, single large scale on operculum above opercular spine, usually covered by mucus and skin; head is slender, elongate (head depth 14-17% SL); first and second lower preopercular pore with separate opening (not fused as in all other species of the genus); otolith slender, length to height ratio 2.2-2.3, otolith length to sulcus length 2.2-2.4, dorsal rim regularly curved without angles (Ref. 57884).
