Indirana tenuilingua is a species of frog that is considered nomen inquirendum.
[2] This species was described by C. R. Narayan Rao based on specimens collected from "Kemphole Ghats, Hassan, Mysore, South India".
[2][3] The original description is not adequate to diagnose the species and contains several inconsistencies.
Attempts to collect new specimens from the type locality have been unsuccessful, and it is not possible to relate this taxon to other Indirana.
For these reasons, it has been placed incertae sedis under Indirana,[3] or relegated to nomen inquirendum.
