Pempheris adusta

diagnosis

Diagnosis. Faint blackish spot on pectoral fin base; pored lateral-line scales 56 – 64 (52 – 58 in Andaman Sea; 51 – 62 in the Pacific); scale rows above lateral line 4 1 / 2 – 6 1 / 2 (usually 5 1 / 2; 4 1 / 2 – 5 1 / 2, usually 4 1 / 2 in Andaman Sea and the Pacific Ocean); circumpeduncular scales 14 – 18, usually 16; distinct blackish band on outer edge of anal fin (rarely faint or only anterior half prominent; usually none in Pacific); blackish band on posterior edge of caudal fin (caudal fin whole yellowish in Andaman Sea); upper-jaw length 14.2 – 15.6 % SL; body depth 41.4 – 45.4 % SL. Pempheris adusta in the Pacific is distinguished from the other members of the genus by the following combination of characters: scales ctenoid and deciduous, thin, semicircular in shape; pored lateral-line scales 51 – 62; scale rows above lateral line 4 1 / 2 – 5 1 / 2 (usually 4 1 / 2); faint blackish spot on pectoral fin base; usually no blackish outer margin on anal fin; dusky band on anal fin base.

Description [based on Indian Ocean specimens]. Body strongly compressed, body width 5.8 – 8.9 in SL; body deep, body depth 2.2 – 2.4 in SL; head length 3.3 – 3.8 in SL; snout very short, rounded, snout length 4.0 – 4.4 in HL; eye large, the diameter 2.2 – 2.6 in HL; interorbital very narrow, 3.1 – 3.7 in HL; dorsal outline loosely convex to dorsal fin base, extending somewhat linearly to caudal peduncle; ventral outline convex to anal fin base, extending somewhat linearly to caudal peduncle; chest usually not keeled, but sometimes weakly keeled. Mouth large and strongly oblique, upper jaw length 1.9 – 2.0 in HL; the maxilla extending to middle of pupil; maxilla broadly expanded posteriorly, its surface with level; lower jaw projecting beyond upper jaw; narrow band of villiform teeth in jaws. Scales ctenoid and deciduous, thin, semicircular in shape; concealed small scales under surface scales; scales of ventral area larger than those of dorsal area; almost all parts of head scaled, except for just anterior to orbit; about one-third of basal part of anal fin covered with small scales; scales above lateral line more deciduous; pored lateral-line scales adherent, running parallel to d
