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 (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 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 的一個成員聚集獨特可區別最後不分枝的背鰭鰭條的形狀是藉由細長的, 柔韌有彈性的而且在後部地有短的鋸齒。 類似 P. cumingii, P. didi 與 P. meingangbii 被前面地有一個深色的縱帶旁的之上與一個深色的圓斑塊在尾梗上; 有別於側線的這些種繼續到尾鰭基底 vs. 只位於 5 到之上 10個鱗片。 與地理接近人區分了 體高 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)
