Etymology: Pethia: Pethia is the generic vernacular name for small cyprinids in Sinhala; tiantian: Specific name derived from tiantian, Mandarin Chinese, meaning heaven. This is in reference to the habitat of the species which is in streams at the foot Himalayas, that is, somewhat close to heaven; noun in apposition.
Eponymy: Tiantian Kullander is the senior author’s son. He, along with his brother ‘Didi’, “…had to repeatedly suffer their parents’ absence searching for these and other fish in faraway lands.” (Also see Kullander & Didi) (Ref. 128868), visit book page.

背棘 (总数) : 0; 背的软条 (总数) : 11 - 12; 臀棘: 0; 臀鳍软条: 8; 脊椎骨: 29 - 31. A member of the Puntius conchonius group uniquely distinguishable by the shape of the last unbranched dorsal fin ray which is slender, flexible and with short serrations posteriorly. Similar to P. cumingii, P. didi and P. meingangbii by presence of a dark vertical bar anteriorly on side and a dark round blotch on caudal peduncle; differs from these species by lateral line continued to caudal fin base vs. present on only 5 to 10 scales. Distinguished from the geographically close P. didi by body depth 35.4-39.8% SL vs. 40.4-48.2% SL and dorsal fin length 23.2-26.0% SL vs. 26.6-31.8% SL, and males with a single dark band across dorsal and anal fin vs. two series of black elongate marks in dorsal fin and one series of black marks in anal fin (Ref. 54351).
Body shape (shape guide): fusiform / normal.
Puntius conchonius 的一个成员聚集独特可区别最后不分枝的背鳍鳍条的形状是藉由细长的, 柔韧有弹性的而且在后部地有短的锯齿。 类似 P. cumingii, P. didi 与 P. meingangbii 被前面地有一个深色的纵带旁的之上与一个深色的圆斑块在尾梗上; 有别于侧线的这些种继续到尾鳍基底 vs. 只位于 5 到之上 10个鳞片。 与那区分了地理地接近的 体高 35.4-39.8% SL 和 40.4-48.2% SL 比較與背鰭長度 23.2-26.0% SL 和 26.6-31.8% SL 比較的 P. didi, 而且雄性有一個深色條紋越過背部的與在臀鰭中的背鰭與一系列的黑點中的臀鰭和二個成列的黑色細長的標誌比較.(參考文獻 54351)
