| Diagnosis |
Diagnosis: 7.0-8.5 scales between lateral line and dorsal fin origin; 39-44 scales in lateral line; 3-5.5 scales between lateral line and mid-belly; 2 scales between lateral line and pelvic fin base; 14-16 circumpeduncular scales; 8-12 dark, vertical bars on sides; dorsal fin darkly pigmentated between the rays (Ref. 81639). Description: mouth terminal, without barbels; scales with divergent striae; dorsal fin originates in advance of the anal; D: II-III,8-9; A: III, 11-14; P:14-15; V: I,8; caudal fin forked (Ref. 81639). Coloration: body olive-brown dorsally, silvery on flanks and ventrum; 8-12 dark, vertical bars, often in pairs, along the flanks; dorsal fin with dark pigmentation between the rays (Ref. 81639). |
