背棘 (总数) : 1; 背的软条 (总数) : 7; 臀鳍软条: 10 - 13; 脊椎骨: 40 - 44. Distinguished from other congeners with a long-based adipose fin (except Mystus cavasius and M. seengtee) in having a combination of a black spot in front of the dorsal-spine base, a dark humeral mark, a body without distinct midlateral stripes, very long maxillary barbels reaching to caudal-fin base, dorsal spine short and feebly serrate, tall dorsal fin, and 22-29 rakers on the first gill arch. Differs from M. cavasius and M. seengtee in possessing a very prominent dark spot at the base of the dorsal spine, a crescentic dark humeral mark, and a dorsal fin with very elongate first and second rays and a markedly concave dorsoposterior margin. The black spot in front of dorsal-spine base is also more prominent in the preserved material of M. falcarius than in either M. cavasius and M. seengtee. Differs further from M. cavasius in having more gill rakers, 22-29 vs. 13-22 (Ref. 56668).
与其他的同类在背部-棘的基底，一个深色的肱骨标志之前黑色斑点在有一个方面具有一个基底长脂鳍 (除了 Mystus cavasius 与 M. seengtee 以外) 组合, 一个身体没有明显的在第一个鳃弓上延伸到尾鳍基底，背棘短与柔弱锯齿状又高的背鳍 , 与 22-29个耙的侧面中央的斑纹，非常长的颚触须区分了。 在背部棘，一个新月形的深色肱骨的标志的基底持有一个非常突出的深色斑点方面有别于 M. cavasius 与 M. seengtee, 與一個背鰭有非常長的第一個與第二個鰭條與顯著凹後背的邊緣。 在背棘基底之前的黑色斑點在 M. falcarius 的被保護的材料也是較突出的超過在任一 M. cavasius 與 M. seengtee 中. 進一步不同於 M. cavasius 有更多的鰓耙, 22-29 vs.13-22.(參考文獻 56668)
描述: 腹鰭有 i,5個鰭條; 臀鰭有 iv,6, iv,7, iv,8 或 iv,9個鰭條.(參考文獻 56668)
Facultative air-breathing in the genus (Ref. 126274); Oviparous, distinct pairing possibly like other members of the same family (Ref. 205).

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00832 (0.00359 - 0.01926), b=2.95 (2.78 - 3.12), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
