背棘 (總數): 0; 背的軟條 (總數): 11-12; 臀棘 0; 臀鰭軟條: 8; 脊椎骨: 29 - 31. A member of the Puntius conchonius group and is most similar to P. cumingii, P. meingangbii and P. tiantian by having a dark vertical bar anteriorly on side and a dark round blotch on caudal peduncle. Differs from P. cumingii by 12 vs. 10 circumpeduncular scales and 3 1/2 vs. 4 1/2 scales above midline; from P. meingangbii by 40.4-48.2% SL vs. 33.3-39.6% SL body depth of adults; and from geographically close P. tiantian by having last unbranched dorsal fin ray thick and strongly serrated instead of slender, flexible and with short serrations posteriorly, body depth 40.4-48.2% SL vs. 35.4-39.8% SL, dorsal fin length 26.6-31.8% SL vs. 23.2-26.0% SL, lateral line limited to six to seven, rarely up to ten anterior scales, vs. continued to caudal fin base, and males with two series of black marks in dorsal fin and one series of black marks in anal fin, vs. a single dark bank in each fin in male P. tiantian. Distinguished form P. phutunio by wider infraorbitals 3+4, extending posteriorly to the margin of the preopercle instead of only halfway to the preopercle, 12 vs. 10 circumpeduncular scales, absence of a dark blotch anteriorly at the base of the dorsal fin, and absence of a dark bank extending obliquely rostrad and ventrad from immediately posterior to the dorsal fin base (Ref. 54351).
Puntius conchonius 的一個成員聚集而且是在側邊與一個深色的圓斑塊上前面地藉由有一個類似 P. cumingii ， P. meingangbii 與 P. tiantian 深色的縱帶的大部分在尾梗上。 vs.10個 circumpeduncular 鱗片在 12 點之前有別於 P. cumingii 與 31/2 vs. 在中線上面的 41/2個鱗片; 從成魚的 40.4-48.2% SL 和 33.3-39.6% SL 體高比較的 P. meingangbii; 而且從地理接近的 P. tiantian 最後藉著具有不分枝的背鰭鰭條厚的而且深鋸齒狀的取代細長的, 柔韌有彈性的而且在後部地有短的鋸齒, 體高 40.4-48.2% SL 和 35.4-39.8% SL 比較, 背鰭長度 26.6-31.8% SL vs.23.2-26.0% SL, 側線僅限於六到七, 很少達到十個前面的鱗片, vs. 繼續的到尾鰭基底, 而且雄性有在背鰭的二個成列的黑點而且在臀鰭中雄性有一系列的黑點, vs. 在雄魚中的在每個鰭的一個深色的淺堆 P. tiantian. 較寬的眶下骨 3+4 的可區別形式 P. phutunio, 向後延伸前鰓蓋骨的到邊緣取代只有的一半前鰓蓋骨,12 vs.10個 circumpeduncular 鱗片, 在背鰭基底前面地缺乏一個黑色斑塊, 而且缺乏深色的淺堆斜地延伸 rostrad 與 ventrad 從緊鄰在背鰭基底後面.(參考文獻 54351)
