Espinhos dorsais (total) : 0; Raios dorsais (total) : 13; Espinhos anais: 0; Raios anais : 9. Lateral line with 10-15 irregular dark blotches, forming dark bars in posterior part of body and usually not meeting their homologues on back; predorsal part of body marbled by irregular spots and saddles; caudal peduncle 1.2-1.7 times longer than deep, its depth 9.7-11.5% SL; eye diameter 12.1-23.9% HL; lateral head length 105.0-123.3 % HL; anus 1.8-3.5 eye diameters in front of anal-fin origin; caudal peduncle with short crests; caudal fin slightly emarginate, median ray 80.8-91.7% of length of upper caudal-fin lobe; eye situated dorsally and interorbital width 21.2-33.8% HL; inner axial stripe absent or faint; caudal-fin base with complete black bar; lateral line complete in most specimens; no suborbital flap in males; dorsal fin with 8 1/2 rays; caudal fin with 9+8 branched rays; pelvic fin with 8 rays (Ref. 40772).
Body shape (shape guide): elongated.
