背的軟條 (總數) : 12; 臀鰭軟條: 8. A member of the group of species with complete or nearly complete lateral line, 8 1/2 branched dorsal rays, 9+8 branched caudal rays and no sexual dimorphism. Can be distinguished by the following characters: 13-14 bars on body, the anterior ones not conspicuously wider than posterior ones; maximum head width 16.6-17.4% SL; eye diameter 3.1-3.6% SL, 14-17% HL; interorbital width 7.3-7.8% SL, 35-36% HL (Ref. 39226). Its slender caudal peduncle (1.23-1.53 times longer than deep) and its color pattern distinguish it from any congener (Ref. 39226). Presence of a dark blotch at dorsal-fin origin; a faint blotch at base of posterior rays of dorsal fin; scales very sparse or absent in front of dorsal fin and on belly (Ref. 12693).
一個群種的成員具有完全的或幾乎側線完整,81/2個分枝的背鰭鰭條,9+8個分枝的尾部鰭條與沒有性的同種二形。 鑑別的特徵是下列的特徵: 在身體上的 13-14條橫帶, 前面的一些不明顯的比在後部的一些寬; 最大的頭部寬度 16.6-17.4% SL; 眼直徑 3.1-3.6% SL,14-17% HL; 眼間骨寬度 7.3-7.8% SL ， 35-36% HL.(參考文獻 39226) 它的細長尾柄 (1.23-1.53 倍深的) 與它的彩色斑紋區別它和任何的同類。 (參考文獻 39226) 在背鰭起點出現一個黑色斑塊; 在背鰭的在後部鰭條的基底的一個模糊的斑塊; 鱗片非常稀疏的或不存在於背鰭的前面與在腹面上.(參考文獻 12693)
Inhabits streams and river backwaters at the driest time of the year (Ref. 39226). Frequently found in large rivers with stony bottom (Ref. 43281). A 5.92 cm SL female with ripe ovulae 1.4-1.6 mm in diameter (Ref. 39226). Not caught commercially (Ref. 12693).
在每年的最乾時間棲息於溪流與河洄水區。 (參考文獻 39226) 時常發現於大河了且底部為石頭的地方.(參考文獻 43281) 5.92 公分 SL 母魚有成熟的卵 1.4-1.6 mm 直徑。 (參考文獻 39226) 不商業地捕捉。 (參考文獻 12693)
