Short description
Identification keys | Morphology | Morphometrics
Dorsal soft rays (total): 17; Anal soft rays: 8. This species is distinguished by the following combination of characters: small esca, 11% of illicium length (including esca); short, very slender illicium, without dermal spinules, its length about 16% SL, 3.5 times in head length; head length about 9 times snout length; short snout, length 6% SL; eye large, 5.6 times in head length; narrow body, maximum width 19% SL; interorbital width narrow, about 5% SL; scale bases subcircular with prominent, strongly divergent, bifurcate spinules (except for those closely associated with pores of the acoustico-lateralis system); spinules variable in length over body; dorsal-fin elements covered with spinules, outer fin membranes naked; first dorsal-fin base short, length 15% SL; second dorsal-fin rays 15, fin base about 57% SL; length of second dorsal-fin spine 1.4 times length of longest ray of second dorsal fin; anal-fin rays 8; body is predominantly pale pink with prominent eyelash-like marking radiating from eye; caudal fin plain, without fine spots (Ref. 82446).
