Morphology | Morphometrics
soft rays: 6. Metamorphosed females distinguished by the following characteristics: have filaments on dorsal surface of head just behind base of the illicium; length of illicium less than 120% SL (72-96% SL); presence of short filaments along entire posterior margin of illicium; escal bulb with an elongate spinulose and darkly pigmented distal prolongation bearing distally flattened papillae; presence of short distal and slender proximal escal filaments; absence of posterior pair of close-set illicial appendage; relatively long dentary teeth (longest 2.9-3.8% SL) in five or six longitudinal series; short caudal fin rays (less than 30% SL) (Ref. 86949).
