Dorsale stekels (totaal) : 8 - 9; Dorsale zachte stralen (totaal) : 9 - 10; Anale stekels: 1; Anale zachte stralen: 8 - 9; Wervels: 34. This species is distinguished by the following character states: snout blunt, snout length/
head length ratio 0.26-0.28, mean 0.27; eye large, but not protruding outward, interorbital width larger than eye diameter, interorbital width/head length ratio 0.22-0.27, mean 0.25 (Ref. 131453).
Cross section: oval.
Found in small creeks or rivers with slow moving, clear water and rocky bottom. Some remains of chitin exoskeleton of crustaceans were found in the anus opening of the holotype, suggesting that this species is carnivorous. During their spawning seasons, the male’s head would turn black with several orange dots on the body sides (Ref. 131453).
