Description: Body elongated, moderately compressed laterally, more compressed in region of caudal peduncle; dorsal head profile rising gently, almost straight, more or less continuous with dorsal body profile to about middle between nape and dorsal-fin origin; dorsal profile decreasing between middle between nape and dorsal-fin origin and about base of last dorsal-fin ray; slightly decreasing until caudal peduncle; ventral profile more or less straight to anal-fin origin (Ref. 111064). Head small, with flat interorbital distance, height at nape less than head length, width at nape greater than depth at nape, without tubercles; snout pointed, transverse groove absent; proboscis not or only slightly elevated from depressed rostral surface; depressed rostral fold poorly expressed; no groove between transverse lobe and lateral surface; eye placed dorso-laterally in anterior half of head; barbels in two pairs; rostral barbel antero-laterally located, shorter yhan eye diameter; maxillary barbel at corner of mouth, shorter than rostral barbel; rostral cap well-developed, fimbriate, papillate on ventral surface; upper lip present as a thin band of papillae; upper jaw almost or completely covered by rostral cap; lower jaw slightly curved or straight; disc elliptical, shorter than wide or as long as wide and narrower than head width through base of maxillary barbel; papillae on anteromedian fold of same size, regularly arranged; groove between anteromedian fold and central callous-pad narrow and deep in some individuals or shallow and wide in others, papillae on latero-posterior flap of same size and distance as on papillae on anteromedian fold; anterior marginal surface of central callous pad without or with sparsely arranged small papillae; papillae on anteromedian fold and on latero-posterior flap almost or completely absent in some individuals; posterior margin of latero-posterior flap extending vertical to anterior or posterior margin of eye; in some individuals, only the posterior tip of latero-posterior flap is free while in others, the whole rim is free (Ref. 111064). Dorsal fin with 3 simple and 7.5 branched rays, last simple ray slightly shorter than or equally long as head length; distal margin concave; origin at middle between snout tip and last scale on caudal-fin base; inserted anterior to vertical from pelvic-fin origin; first branched ray longest, tip of last branched ray reaching vertical of anus; pectoral fin with 1 simple and 12 branched rays, reaching midway or slightly beyond distance between pectoral- and pelvic-fin origin, length shorter than head length; pelvic fin with 1 simple and 7-8 branched rays, reaching to, or slightly in front of anus, origin closer to anal-fin origin than to pectoral-fin origin, inserted below second or fourth branched dorsal-fin ray; anal fin short, with 3 simple and 5.5 branched rays; first branched ray longest, reaching to dark grey or black blotch on posterior caudal peduncle or slightly anterior to it; distal margin concave; origin almost in middle between caudal-fin base and pelvic-fin origin; 2 scales between anus and anal-fin origin; caudal fin forked, with 9+8 branched rays; tip of lobes pointed; upper lobe longer than lower lobe (Ref. 111064). With 8-12 small and very short gill rakers on lower limb of first gill arch (Ref. 111064). Lateral line complete, with 34 scales on body and 2 scales on anterior caudal fin; transverse scale rows above lateral line 3.5-4.5; between lateral line and pelvic-fin origin 3.5 and between lateral line and anal-fin origin 3.5-4.5; circumpeduncular scale rows 14-16; predorsal scales smaller than flank scales, irregularly arranged, anterior predorsal scales deeply embedded; belly and breast behind pectoral-fin origin scales, scales deeply embedded; one long axillary scale at base of pelvic fin, and 6-8 scales between posteriormost pelvic-fin base and anus (Ref. 111064).

Colouration: Colouration in living specimens: head, back and flank brown with an olive green hue; a faith yellow or golden mid-dorsal stripe on back; ventral surface pale white; flank darkest along midlateral line with an irregular shaped, wide, dark-brown stripe; caudal, dorsal, pectoral and pelvic-fins with yellowish or greenish rays and hyaline membranes; branched dorsal-fin ray 4-7.5 with a black spot slightly above base, in some individuals black spot continuous with black dorsal-fin rays; anal fin hyaline or with greenish pigments at its distal part; a dark-brown blotch behind upper edge of operculum; a dark-brown blotch at middle of posterior-most caudal peduncle in individuals smaller than 40 mm standard length (Ref. 111064). Colouration in ethanol-preserved specimens: head, back and flank brown; ventral surface pale grey; flank darker brown along midlateral line than on upper and lower flank, scales with dark-brown margin and pale-brown centre giving the flank a slightly reticulate pattern; individual flank scales whitish in centre; caudal, dorsal, pectoral and pelvic fins with grey rays and hyaline membranes; branched dorsal-fin ray 4-7.5 with a black spot slightly above base, in some individuals, black spot continuous with black dorsal-fin rays; anal fin hyaline or grey at its distal part; a dark-brown blotch behind upper edge of operculum; a dark-brown blotch at middle of posterior-most caudal peduncle in individuals smaller than 40 mm standard length (Ref. 111064).
