Diagnosis

Description: Body spear-shaped from side and wedge-shaped in cross-section (Ref. 52193). Head obtusely pointed; eyes latero-ventral more visible from below; mouth terminal; maxilla exposed when shut, upper jaw notched for median process on lower jaw, posterior tip of upper jaw hidden when mouth closed; lips thin; teeth small, villiform; eyes lateral with well developed adipose eyelids (Ref. 2109, 52193). Dorsal fin with 4 spines, 2 unbranched and 7-8 branched rays; anal fin with 3 spines and 9 soft rays; scaly process at base of first dorsal fin; origin of second dorsal fin behind origin of anal fin; pectoral fins set at declined angle to body, 86-97% of head length, reaching beyond eye when folded forward, and reaching below origin of first dorsal fin with axillary scale nearly half the length of fin (Ref. 2109, 52193). Scales in lateral series 30-43, scales with membranous digitated hind margin (Ref. 2109).

Colouration: Colour greenish-grey dorsally, sides silvery; second dorsal and anal fin with black margins (Ref. 9812). Faint longitudinal stripes along upper scale rows (Ref. 52193).
