Short description
Identification keys | Morphology | Morphometrics
Dorsal soft rays (total): 6; Anal soft rays: 4. Characterized by having escal morphology: esca with stout, internally pigmented anterior appendage, distal end is bifurcated bearing numerous unpigmented tapering filaments; three pairs of filamentous medial escal appendages, most anterior pair longest, almost as long as escal bulb; terminal escal papilla rounded with distal streak of pigment; unpigmented tapering posterior escal appendage, slightly expanded and trifurcated at distal tip; absence of lateral escal appendages; stout, unpigmented anterolateral escal appendage bearing few small filaments; subopercle without indentation on posterodorsal margin; length of ventral fork of opercle; 21.4-23.8% SL; ratio of lengths of the dorsal and ventral forks of opercle 0.38-0.47; absence of epibranchial teeth; presence of teeth on pharyngobranchial II; upper jaw teeth 20-65, lower jaw teeth 27-70; teeth on vomer 4-8; dorsal fin rays 6; anal fin rays 4; pectoral fin rays 16-17; head length 35.7-38.1% SL; head depth 37.1-38.6% SL; premaxilla length 25.7-31.7% SL; length of lower jaw 38.1-38.6% SL; length of illicium 35.7-60% SL (Ref. 86949).
