Description: Body shallow and oval to slightly pyriform; caudal peduncle shallow (Ref. 126312). Head long, narrow, and with a straight to weakly convex dorsal outline and a weak concavity above eye; eye small and high on head; interorbital area narrow; cheek and lacrimal deep (Ref. 126312). Snout long, rounded in dorsal outline, acute in lateral view, and slopes gently at 30-45°; premaxillary pedicel average in length and strongly prominent; jaws isognathous to prognathous, long, slim, very narrow, and rounded in dorsal view; gape large and slopes gently at 20-25°; maxilla extends to between verticals through anterior point of orbit and just past this point; lower jaw relatively shallow and with a straight ventral outline in lateral view, mental prominence strongly developed, and lower jaw side steep with an inclination of 35-40° to horizontal in anterior view; upper jaw expanded anteriorly and ventrally; lips and oral mucosa thin (Ref. 126312). Neurocranium shallow, ethmo-vomerine block decurved, preorbital region very shallow, 18-20% of neurocranium length, orbital region shallow, 26-28% of neurocranium length, and supraoccipital crest shallow and wedge-shaped (Ref. 126312). Outer oral teeth few, unicuspid, and very large; necks stout, conical, and straight; crowns straight to weakly recurved, and acutely pointed; dental arcades rounded; outer teeth widely and irregularly set with neck-distances of 1-4 neck-widths; in upper jaw, 1-2 posteriormost teeth enlarged; inner teeth small, recurved, unicuspid, and acutely pointed; tooth bands very slender crescent-shaped with 1-2 rows of inner teeth, and narrow posteriorly until outer row remains past 2/3 length of tooth band; inner teeth widely and irregularly set on 1-2 outer tooth neck-widths from outer row; implantation erect in first row and recumbent in subsequent rows; in upper jaw, size decreases slightly buccally and posteriorly (Ref. 126312). Lower pharyngeal bone long, very narrow, slim, and shallow over whole length; pharyngeal teeth relatively large and slender; major cusps acutely pointed; cusp gaps concave; minor cusps and cusp protuberances very small; teeth in two median longitudinal rows equal in size and form to lateral teeth, 12 in each row; posterior transverse row with 16-18 teeth, implanted recumbently with a lateral inclination; major cusps weakly recurved, bluntly pointed, and laterally compressed; minor cusps mostly absent (Ref. 126312). Chest scales small; transition to larger flank scales gradual; minute scales on proximal half of caudal fin; scales on longitudinal line 32-33, scales on upper lateral line 19-22, scales on lower lateral line 8-10, scales between dorsal fin and upper lateral line 5-6, scales between upper lataeral line and anal fin 9-11, scales around caudal peduncle 16-19, scales between pectoral and pelvic fins 5-7, infraorbital cheek scales 4-5, postorbital cheek scales 9-12 (Ref. 126312). Caudal fin emarginate; dorsal and anal fins reach to between verticals through two scales anterior to and one scale posterior to caudal-fin base; pectoral fin reaches to between anal opening and second anal-fin spine; pelvic fin reaches to between first and second anal-fin spines; first branched pelvic-fin ray elongated (Ref. 126312). Ceratobranchial gill rakers in outer row of first gill arch short, stout, and simple; posteriormost rakers anvil-shaped to weakly bifid; epibranchial gill rakers slender and simple (Ref. 126312).

Colouration: Colouration in life of dominant males: body yellow; operculum, cheek, and anterior part of flank orange; belly and chest white; snout dusky; lower jaw and lips pink; eye with (dark) grey outer ring and silver to golden inner ring; nostril and lacrimal stripes faint; mental blotch present; pectoral fin yellow; pelvic fin black; dorsal fin hyaline to dusky and with black lappets and a dusky posterior part; anal fin faint crimson and with 2-3 very large orange egg-spots with hyaline rings; caudal fin dusky and with a faint crimson ventral part and a maculated dorsal part (Ref. 126312). Non-domninant males: anterior part of flank, operculum, and cheek with pink sheen; anal fin with crimson anterior part and hyaline posterior part; caudal fin uniformly dusky (Ref. 126312). Colouration in life of females and juveniles: body, operculum, and cheek yellow; belly and chest white; lacrimal and lower jaw pink; snout dusky; eye with (dark) grey outer ring and silver to golden inner ring; nostril and interorbital stripes faint; mental blotch present; pectoral, anal, and caudal fins yellow; anal fin with a white base; caudal fin with a dusky base; dorsal fin hyaline and with black lappets and a dusky distal part (Ref. 126312). Preserved colouration: Body whitish; dorsum and cheek brown; belly, chest, and operculum white; snout dusky; nostril stripe well-defined; lacrimal stripe and mental blotch present; interorbital stripe and nape band faint; pectoral fin dusky; pelvic fin yellowish in females black in males; dorsal fin dusky and with black lappets and sooty posterior part; anal fin yellowish and with 1-2 large egg-spots; caudal fin dusky and with a maculated dorsal part (Ref. 126312).
