Size 110mm or 4.3" SL. Find near, nearer or same sized spp.
IdentificationThe bagrid catfish genus Olyra is known from the Ganges-Brahmaputra river system in the northern part of the Indian subcontinent. It is also known from localities southwards to the Manimalai River in southwestern India and eastwards to the Mae Klong River drainage in western Thailand. The genus is a supported monophyletic group diagnosed by the following combination of external characters: anguilliform body; unossified first and second dorsal-fin elements; and greatly enlarged upper caudal-fin lobe.

Distinguished from congeners by the extremely long upper lobe of the (forked) caudal fin. The populations from the Tenasserim region in southern Myanmar and the Mae Khlong drainage in western Thailand may represent distinct species.
