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..

Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic; depth range 0 - 1 m (Ref. 54351). Tropical
Asia: northern Myanmar.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 4.5 cm SL male/unsexed; (Ref. 54351)
soft rays: 8;
Vertebrae: 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).
Occurs in a small hill stream, about 3 m wide on average, flowing through low forest, with grass and shrub along banks and over a varied bottom with rock, gravel and sand (Ref. 54351).
