Dorsale zachte stralen (totaal) : 10 - 11; Anale zachte stralen: 8. Distinguished from congeners by its unique color pattern consisting of 21-25 dark brown tiger-stripe bars on side of body, bars not reaching venter. Other diagnostic characters include: head short, 4.1-5.4 times in standard length; interorbital width 48.1% HL (10.1% SL); pelvic-fin length 97.0% HL (20.3% SL), approximately equal to head length; length of caudal peduncle 44.8% HL (9.3% SL); dorsal fin with 4 simple rays and 6½ or 7½ branched rays (Ref. 93077).
Found in a stream near a water fall and terraced rice fields with fast flowing, clear water, width of 3-4 m and depth of 3.75 cm. Occurs over substrates of mixed gravel, mud and sand. Other species encountered at the collection site include Schistura breviceps, S. pridii, S. spilota, Oreoglanis siamensis, Devario sp., Scaphiodonichthys burmanicus and Channa gachua (Ref. 93077).
