Descriptive characteristics of juvenile and adult

Striking features none
Body shape lateral fusiform / normal
Cross section
Dorsal head profile more or less straight
Type of eyes more or less normal
Type of mouth/snout more or less normal
Position of mouth terminal
Type of scales cycloid scales

Diagnosis: 2 scale rows between lateral line and scaly process at pelvic-fin bases; eye < 70% of interorbital space (Ref. 2880, 81279). Dorsal-fin origin at about same level as pelvic-fin insertions; tips of adipose and dorsal fins black; forked edge of caudal fin black (Ref. 2880, 80290, 81279).

Description: gill rakers few (5-9/9-12), but rather long; rakers of first gill arch normally developed; body profile less elongate than H. forskalii (Ref. 2880, 80290, 81279). Dorsal fin with 2 unbranched and 8 branched rays; anal fin with 3 unbranched and 12 branched rays; 14 scales around caudal peduncle (Ref. 11970).

Coloration: ground color similar to that of H. forskalii, but in H. vittatus tips of dorsal and adipose fin black and fork of caudal fin black-edged; dark coloration may also extend unto median caudal rays, forming crescent-shaped blotch (Ref. 80290, 81279).
