Body depth about 4 times in SL; 8 branched dorsal rays; 4 scale rows between lateral line and mid-ventral row in front of pelvic fins; 11-12 predorsal scales; uniformly dark greenish body in life; caudal with no noticeable marks (Ref. 43281). Comprises four distinct forms or morphs (Poropuntius bolovenensis bolovenensis, P. bolovenensis acuticeps, P. bolovenensis glaridostoma and P. bolovenensis laticeps). These are morphs of a species with pronounced trophic polymorphism. Most specimens have mouth parts resembling those in many other barbin species, including most species of Poropuntius with well-developed barbels, such as P. deauratus. P. bolovenensis is based on this form. The four morphs also have slight differences in body proportions (head length, body depth, caudal peduncle length) and meristic characters (counts of dorsal fin rays, gill rakers and scales). Their coloration in life is virtually identical, one reason for considering that they represent a single species. All of the smaller individuals have mouth parts of the generalized type (Ref. 35912)
大约标准体长比率 4 的体高; 8个分枝的背鳍鳍条; 4 鳞片列在侧线之间与腹面中央在腹鳍之前的列; 11-12个前背的鳞片; 活着时的全黑色呈绿色的身体; 尾鳍有没有易见的标志.(参考文献 43281) 包含四个明显不同的造型或变种 ( Poropuntius bolovenensis bolovenensis ， P. bolovenensis acuticeps ， P. bolovenensis glaridostoma 与 P. bolovenensis laticeps) 。 这些是种的变种有明显的营养多型性。 大多数的标本让嘴部份相似那些在许多其他的 barbin 种, 包括 Poropuntius 的大多数鱼种有发展良好的触须，例如 P. deauratus 。 P. bolovenensis 是以这一个形式为依据。 这四个变种也有身体比例 (头长，体高 , 尾柄长度) 与体节形质特徵特徵 (背鳍鳍条，鳃耙与鳞片的计数) 的轻微的不同。 他们的颜色活着时事实上同一,一个的理由从各方面来看它们代表一个种。 所有的较小个体有被推广的类型的嘴部份 (参考文献 35912)
