توصيف مختصر
كليدهاي شناسايي | ريخت شناسي | ريخت ستجي بوسيله انداره گيري
Caudal peduncle 1.2-1.4 times longer than deep, depth 8.6-9.7 %SL; anus closer to posterior extremity of pelvic-fin base than caudal-fin origin; 18-30 dark brown bars on body, their width conspicuously smaller than eye diameter, very irregularly shaped and spaced, more or less connected along lateral line to form a saw-toothed stripe; juveniles with 5-6 broad black bars on body and a large black blotch on anterior half of caudal fin; 5 large saddles on back; pelvic and pectoral fins yellow in life, with a series of dark brown marks; 2-3 irregular row of brown spots on dorsal fin, 2 irregular black bars or rows of spots on caudal fin; 15-16 branched pectoral-fin rays; 8 branched pelvic-fin rays (Ref. 36949).
Collected in swift creeks under forest cover (Ref. 36949). Also recorded from a stream with clear water ((16 °C; pH 8.1; 250 μs/cm; measured on 1 January 2011 at 11:00 am) that flowed over boulders and rocks with moderate to fast current. Found syntopic with nemacheilids Schistura macrocephalus and Pteronemacheilus meridionalis, the snakehead Channa gachua, and cyprinids such as Barilius pulchellus, Devario chrysotaeniatus, Poropuntius huangchuchieni, and Scaphiodonichthys acanthopterus (Ref. 95066).
