Short description
Identification keys | Morphology | Morphometrics
Dorsal soft rays (total): 5 - 6; Anal soft rays: 4. Characterized by having escal morphology: esca with large complex anterior appendage consisting of a wide compressed base bearing a relatively short unpaired branched filament on posterior margin, 2 extremely long distal filaments that bifurcate as many as five times, and a stout, bifurcated medial filament, each branch becomes highly branched distally; pair of filamentous, highly branched medial escal appendages less than length of escal bulb; terminal escal papilla with a single distal streak of pigment; slender unbranched posterior escal appendage less than length of escal bulb; relatively short, filamentous, branched anterolateral appendage on each side; long and narrow subopercle, dorsal end tapering, rounded or pointed distally, without indentation on posterodorsal margin; length of ventral fork of opercle 26.6-27.7% SL; ratio of lengths of the dorsal and ventral forks of opercle 0.47-0.51; absence of epibranchial teeth; presence of teeth on pharyngobranchial II; upper jaw teeth 60-67, lower jaw teeth 56-76; teeth on vomer 5-6; dorsal fin rays 5-6; anal fin rays 4; pectoral fin rays 15-17; head length 43.8-47.7% SL; head depth 42.4-50.0% SL; premaxilla length 35.9-40.0% SL; length of lower jaw 50.0-52.7% SL; length of illicium 37.5-107.7% SL (Ref. 86949).
