Callula triangularis Günther, 1876
Ramanella triangularis (Günther, 1876)
|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.
The taxonomy of this species needs to be resolved, as current collections probably represent more than one taxon.
|Red List Category & Criteria:||Vulnerable B1ab(iii) ver 3.1|
|Assessor(s):||Biju, S.D., Dasaramji Buddhe, G., Dutta, S., Vasudevan, K., Srinivasulu, C. & Vijayakumar, S.P.|
|Reviewer(s):||Stuart, S.N., Chanson, J.S. & Cox, N.A.|
Listed as Vulnerable, because its Extent of Occurrence is less than 20,000 km2, its distribution is severely fragmented, and there is a continuing decline in the extent and quality of its forest habitat in southern India.
|Previously published Red List assessments:|
|Range Description:||This species is believed to be restricted to the southern Western Ghats, Ponmudi Hills (Kerala and Tamil Nadu), Wayanad and the Silent Valley (Kerala), and Saklespur, Hassan District (Karnataka) in India. The distribution record in the Shevaroys Hills of the Eastern Ghats, as reported in Dutta (1997), requires further confirmation. It has been reported from elevations of 300-950m asl.|

|Population:||It is a locally common species.|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||It is found in tropical moist evergreen and deciduous forests, and coffee plantations with a natural canopy cover. It can be found in tree holes between two and four metres above ground level (Inger et al. 1984), and in the leaf-litter substrate. It may also be found in abandoned eucalyptus plantations close to forest. It presumably breeds by larval development, like other members of its genus, but it is not known whether or not it requires waterbodies for breeding.|
|Major Threat(s):||The major threat to this species is habitat loss due to conversion to agricultural land (including coffee plantations) and human settlements.|
|Conservation Actions:||It has been recorded from Wynaad Wildlife Sanctuary and Silent Valley National Park, both in Kerala, which form part of the Nilgiri Biosphere Reserve. It is also present in the Ponmudi Hills of Kerala.|
