Raorchestes ravii Zachariah, Dinesh, Kunhikrishnan, Das, Raju, Radhakrishnan, Palot, and Kalesh, 2011 This taxon was described based on two specimens from "Naduvattam (11 23? N 76 34? E; 1,890 m.a.s.l), Nilgiri district, Tamil Nadu, India" . However, subsequent studies could not unambiguously report new collections of this species from its type locality. ... ... Our morphological examination of the type specimens of R. ravii and comparison with R. chromasynchysi, as also indicated by Vijayakumar et al. (2014), suggests that R. ravii is a member of the Raorchestes chromasynchysi group (see 'Grouping of species using integrative approaches') due to the combination of characters such as small adult size (male SVL 20-23 mm); pointed snout; dorsal skin with horny spinules; presence of horny ridge between the eyes and another extending from the snout tip to the vent (mentioned as absent by Zachariah et al., 2011; but observed to be present on the holotype); tongue with papillae (mentioned as absent by Zachariah et al., 2011; but observed to be present on the holotype); iris golden brown, horizontally not divided into lighter upper and darker lower halves; and foot webbing extending up to or above the second subarticular tubercle on either side of toe IV. Furthermore, R. chromasynchysi that has been reported from Naduvattam is a confusing frog with highly variable colouration and markings, including brown morphs that show the presence of dark X or H-shaped marks on the dorsum, brown band connecting the eyes, lateral surfaces of head and supratympanic region darker brown, flanks and groin without contrasting blotches, and limbs irregularly barred. ... ...
