Diagnosis: Caudal fin membrane clear towards vivid yellow at fork; anal fin extending two thirds of length of caudal peduncle; caudal peduncle moderately long; operculum entirely, not partially, shiny; body midline silver, not black; iris dark to light grey, not white; head with tubercles along lower jaw and lower head in breeding males; snout rounded, not pointed, darker dorsally; pelvic fin melanophores absent (Ref. 116496).

Description: Body elongated, somewhat fusiform, laterally compressed; maximum body depth at middle pelvic and pectoral fin origin; pre-dorsal profile straight or slightly convex behind head (Ref. 116496). Head length 20% of standard length, with tubercles along lower jaw and lower head; snout rounded, short, 30% of head length; mouth terminal, slightly crescent-shaped with long anterior side, reaching anterior border of orbit; nostrils large, level with dorsal margin of eye, separated from orbit by less than one orbit radius; tubular anterior naris short, adjacent to open posterior naris; eye lateral, visible from above and below, more prominent, diameter 35% of head length (Ref. 116496). First gill arch with 8+3 gill rakers on cerato- and epibranchial arms respectively; gill rakers long, pointed, widely-spaced; pharyngeal bones in three rows; pharyngeal teeth 4,3,2-2,3,4, robust and long, falcate (Ref. 116496). Fins large in relation to body size; dorsal fin closer to caudal fin than tip of snout; more or less above origin of anal fin; length 17% of standard length; posterior margin straight; rays soft; anterior-most branched fin ray longest; pectoral fins largest, reaching 1/2 to 3/4 distance to base of pelvic fin; fin lacking lobe at base; pelvic fins reaching 2/3 distance to base of anal fin, relatively small, pointed; fin lacking basal lobe; anal fin moderately long, extending 2/3 length of caudal peduncle; last unbranched ray longest; ano-genital opening at anterior of base of anal fin; caudal peduncle moderately long; caudal fin forked; lobes with slightly concave interior and extending into point; upper lobe shorter; dorsal fin with 2 unbranched and 7-8 branched rays; anal fin with 3 unbranched and 12-17 branched rays (Ref. 52193, 116496). Scales small to medium relative to body size; in regular rows; cycloid, slightly elongate; radially striate; base of anal fin lacking sheath scales; lateral line present, complete; dipping sharply towards ventral at tip of pectoral fin; joining midline at posterior of caudal peduncle; 45-59 scales along lateral line, 16-18 around caudal peduncle (Ref. 52193, 116496).

Colouration: Live colouration: body silver, without vertical bars or bands; dorsum pale brown with small dark brown melanophores, midline silver; snout darker dorsally; operculum entirely metallic silver; iris dark to light grey; dorsal fin membrane clear; rays clear with olive melanophores; fading towards tips; caudal fin membrane clear, vivid yellow at fork; rays light olive; rays lighter towards tips; melanophores small, dark, fading towards rear; anal fin rays clear; membrane clear; dark spotting above origin; melanophores dark olive fading towards tips; pectoral fin membranes clear; rays clear; first ray with few dark melanophores; pelvic fin rays clear; membrane clear (Ref. 116496). Preserved colouration: body and head white and silver with dark spotting sparse to densely packed towards caudal fin on midline and on dorsal surface; scales on dorsal surface lightly pigmented; ventral scale pigmentation as intense as dorsal surface; dorsal surface of head lightly pigmented; melanophores small, dark; clustered on rear of head, below orbit and on lips and snout; along midline, increasing in intensity to caudal fin; browner on dorsal surface above midline; forming a small, dark line above anal fin; operculum and posterior edge of orbit with silver sheen; membranes between fin rays clear; pelvic fin clear membranes and rays; dorsal, caudal and pectoral fin membranes clear; rays with melanophores small, dark, widely-spaced; rays pale grey (Ref. 116496).
