Diagnosis |
Diagnosis: Last simple dorsal-fin ray smooth on hind margin; scale formula 3.5/25-29/3.5; 2.5 scales between lateral line and pelvic-fin base; 12 scales around caudal peduncle; 8 branched dorsal fin rays; two pairs of short barbels; anterior barbel not reaching anterior margin of eye; posterior barbel not extending beyond centre of eye; lateral line complete and slightly depressed below dorsal fin; maximum reported size 33 mm SL; sides with 3 small spots connected by a more or less dark band (Ref. 2940, 81282). Description: Dorsal profile slightly convex; mouth subinferior; gill rakers short (Ref. 81282). Dorsal fin with 3 unbranched and 8 branched rays; anal fin with 3 unbranched and 5 branched rays; pectoral fin with 13-15 rays; pelvic fin with 1 unbranched and 7 branched rays (Ref. 2940, 81282). Colouration: Many individuals have 3 small spots aligned on middle of sides, 1st above 6th and 7th lateral-line scales, 2nd below 1st dorsal-fin ray and 3rd at end of caudal peduncle; spots are frequently united by more or less regular and distinct band of melanophores; in some specimens spots are hardly visible (suffused by longitudinal band) (Ref. 2940, 81282). |
