サイズ / 重さ / 年齢
Maturity: Lm ? range ? - ? cm
Max length : 150 cm TL オス/雌雄の選別がない; (Ref. 58784)
背鰭 (合計) : 13; 臀鰭: 8 - 9; 脊つい: 36 - 37. Differs from its congeners in having larger (fewer) scales, scale rows between lateral line scale row and pelvic fin 3, fewer vertebrae, weak stripes, only three stripes between lateral line scale row and pelvic fin rather than four, and free posterior margin of left and right sides of lower lip widely separated at midline. Barbels relatively long.
Occurs in upland reaches of large and medium sized rivers (Ref. 12693). Feeds on benthic organisms and insect larvae (Ref. 58784). Undergoes upstream movement for spawning (Ref. 58784). Little is known about this species due to past confusion with P. jullieni (Ref. 12693).
