Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 0; Dorsal soft rays (total): 10 - 11; Anal spines: 0; Anal soft rays: 8 - 9. Diagnosis: body slender, cylindrical (Ref. 52193), body depth 14.1-15.0% SL (Ref. 89116). Head smooth, rounded in front, flat below; mouth ventral, tadpole-like (Ref. 52193). Head length 18.4-22.8% SL; predorsal length 52.5-56.8% SL; prepelvic length 55.0-57.0% SL; preanal length 77.2-82.7% SL; caudal peduncle length 15.0-19.5% SL; snout length 42.7-50.0% HL; postorbital distance 42.7-50.0% HL (Ref. 89116). Eye superolateral, its diameter 18.2-20.0% HL (Ref. 89116), 5-6 times in HL, 2.2-2.27 times in interorbital distance, 1.7-2.2 times in snout length (Ref. 89112). Interorbital width 42.7-45.4% HL (Ref. 89116). Dorsal fin origin before first ray of pelvic fin (Ref. 89112), nearer base of caudal fin than snout (Ref. 52193). Origin of anal fin nearer base of caudal than pelvics; fins short (Ref. 52193).
Coloration: Alcohol preserved: basic ground color pale yellow-brown; lateral series of large, dark blotches along the flanks with numerous smaller dark markings on dorsal surface; caudal fin with diagonal series of small dark markings (Ref. 89116).
