Scientific Name: Uperodon obscurus (Günther, 1864)
Callula obscura Günther, 1864
Ramanella obscura (Günther, 1864)
Taxonomic Source(s): Peloso, P.L.V., Frost, D.R., Richards, S.J., Rodrigues, M.T., Donnellan, S.C., Matsui, M., Raxworthy, C.J., Biju, S.D., Lemmon, E.M., Lemmon, A.R. and Wheeler, W.C. 2015. The impact of anchored phylogenomics and taxon sampling on phylogenetic inference in narrow-mouthed frogs (Anura, Microhylidae). Cladistics 32: 113–140.
Taxonomic Notes: When the first assessment for this species was published (in 2004) it was under the generic name Ramanella. Ramanella Rao & Ramanna, 1925 is now recognised as a junior synonym of Uperodon Duméril & Bibron, 1841 (Peloso et al. 2016), hence the transfer of this species to the genus Uperodon. This is not a reassessment of the status of this species; instead it is an updated version of the original assessment to reflect this taxonomic change.

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2016
Date Assessed: 2004-05-02
Needs updating
Assessor(s): Manamendra-Arachchi, K. & de Silva, A.
Reviewer(s): Stuart, S.N., Chanson, J.S. & Cox, N.A.
Listed as Near Threatened since, although its Extent of Occurrence is much less than 5,000 km2, it is common and adaptable with a presumed large population, and it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
