This dorsally-spotted and short-barbeled species is distinguished from other in 'mentella' group by this set of characters: a short (about 8-12% SL) bicolored mental barbel with uniformly dorsally dark-pigmented or spotted stem and rather long (65-68% of barbel length), inexpressive (barely wider than stem), light (creamy, whitish or light-orange in live specimens) and pointed terminal expansion, reaching nostrils or anterior edge of orbit in backward extended mode over the snout with mouth closed; terminal expansion composed of low, densely distributed folds with serrated or scalloped ridges and rosettes of leaf-like processes; lower jaw evidently protruding with visible teeth on symphysis when mouth closed; interorbital distance wide (about 7% SL); second dorsal fin with straight (not sinuous distally) rays, medium in height within males of the genus (about 21% SL), with conspicuous blackish-colored anterior elevated lobe, dark basally and lightish or somewhat variegated distally in posterior part; dorsal surface of head and area anterior to first dorsal fin covered by dark-brown spots and irregular markings; breast and belly dark-brown and blackish, both lacking in evident dark sharp spots or markings; mandibular and maxillar oral valves light or light-brownish; caudal and pectoral fins dark or blackish anteriorly, sometime with several inconspicuous stripes, and uniformly light in posterior narrow margin, anal and pelvic (both sides) fins blackish basally and light distally (Ref. 92304).

Description: First dorsal fin with 2 flexible spines; second dorsal fin with 27-28 rays; anal fin with 17-18 rays; pectoral fins with 19-21 rays; gill rakers: anterior 8-9, posterior 7-8, total 16; upper lateral line with 24-29 pores (tubular scales); middle lateral line with 12-19 pores (tubular scales); cephalic lateral line pores: preoperculo-mandibular canal 9; infraorbital canal 7; supraorbital 4, with 2 nasal and 2 interorbital pores; coronal commissure 1 central pore; temporal 6; supratemporal 2, disrupted at middle, with 1 left and 1 right pores; vertebrae: 16 + 21 = 37. Body scaleless, robust and tadpole-like from dorsal and ventral view, somewhat dorsoventrally flattened anteriorly, with large and rather wide head and with short mental barbel on the top of the lower jaw; upper surface of head and nape spotted by rounded or/ and irregular dark markings. Elongated body is low in height, horizontally oval in anterior cross section. Dorsal profile of head sloping, gradually rising backward; lateral eyes and half-superior mouth is not protrusible (Ref. 92304).
