Raios dorsais moles (total) : 34 - 38; Raios anais moles: 23 - 26; Vértebras: 42 - 45. Dorsum black to purplish-black, posterior part below lateral lines sometimes with black oblique streaks on dark grey background; ventrum dirty white to grey, with scattered darker grey spots; throat with bluish spots and blotches on dark-grey background, appearing marbled.. Head distinctly flatter and less convex (postorbital depth 30.9-35% HL); head length 33.2-34% SL; head width 16.9-19% SL; pelvic fins 2.3-3% of inter-pelvic fin distance (Ref. 44371).
Obligate air-breathing (Ref. 126274); Maximum length recorded is 19.4 cm SL (Ref. 116754). abundant in ditches, ponds and hill streams
of the sampled locations. The holotype was collected from
clear, slow flowing water with cobble substrate without
