成熟度: Lm ? range ? - ? cm
Max length : 12.8 cm SL 雄魚/尚未辨別雌雄; (Ref. 26663)
脊椎骨: 35 - 37. Differs from all other species of Mystus except M. mysticetus in having over 40 gill rakers on first gill arch. It differs from M. mysticetus in having eyes dorsolateral (rather than lateral) and from all striped Mystus of Thailand in having head from snout tip to behind eye very flat and relatively broad, dorsal margin of eye nearly flush with dorsal profile of head, interorbital width twice eye diameter. Anal fin margin distinctly rounded (truncate or falcate in other striped Mystus of Thailand) (Ref. 26663). Eyes visible from above, but not from below; adipose fin well separated from dorsal-fin base (Ref. 12693); adipose fin base longer than anal base (Ref. 43281).
Body shape (shape guide): elongated.
有別於除了 M. mysticetus 以外的所有其他種的 Mystus 在第一個鰓弓上超過 40個鰓耙有。 它有別於 M. mysticetus 有眼背外側的 (而不是側面的) 而且從泰國的所有有斑紋 Mystus 有頭部從吻尖到在後眼非常平坦的與相當寬的, 眼的上緣幾乎以頭部的背面輪廓臉發紅, 眼間骨寬度兩次眼直徑。 臀鰭邊緣明顯地圓的 (截形或鐮刀狀的在泰國的其他有斑紋 Mystus 中) 。 (參考文獻 26663) 眼看得見的從上方, 但是不從下方; 脂鰭與背鰭基底分得很開;(參考文獻 12693) 脂鰭基底長度超過臀鰭基底.(參考文獻 43281)
Facultative air-breathing in the genus (Ref. 126274); Adults inhabit rivers and streams. Often occur in mixed schools with M. mysticetus which congregate around tree limbs and other solid objects, browsing the hard surfaces for zooplankton, crustaceans, aquatic insects and some plant debris. Move into the flooded forest during the flood season. Oviparous, distinct pairing possibly like other members of the same family (Ref. 205). May be sold fresh or smoked on a skewer (Ref. 12693).
成魚棲息於河川與溪流。 時常用樹木斷枝與其他的堅硬目標的周圍聚集的 M. mysticetus 出現在混合的魚群, 翻掘堅硬的表面尋找浮游動物，甲殼動物，水生昆蟲與一些植物殘枝。 在洪水季節的時候移進被水淹沒的森林中。 卵生的, 明顯的成對可能地像其他的相同該科的成員.(參考文獻 205) 可能是舊的成串新鮮或燻製.(參考文獻 12693)
