| description | <p>Leaping frogs of the family Ranixalidae are endemic to the Western Ghats of India and are currently placed in a single genus, <em>Indirana</em>. Based on specimens collected from their entire range and a comprehensive study of type material defining all known species, we propose a revised taxonomy for the leaping frogs using an integrative approach including an analysis of the mitochondrial 16S rRNA and nuclear rhodopsin genes, as well as multivariate morphometrics. Both genetic and morphological analyses suggest that the genus <em>Indirana</em> is paraphyletic and a distinct monophyletic group, <em>Walkerana</em> gen. nov is described herein. The new genus is separated from <em>Indirana</em> sensu stricto by an apomorphic character state of reduced webbing, with one phalange free on the first and second toe (vs. no free phalanges), two phalanges free on the third and fifth toe (vs. one free phalange), and three phalanges free on the fourth toe (vs. 2–2½ phalanges free). This review includes (i) identification of lectotypes and redescription of three species of the genus <em>Walkerana</em>; (ii) identification of lectotypes for <em>Indirana beddomii</em> and <em>I. semipalmata</em> and their redescription; (iii) redescription of <em>I. brachytarsus</em> and <em>I. gundia</em>; and (iv) descriptions of four new species, namely, <em>I. duboisi</em> and <em>I. tysoni</em> from north of the Palghat gap, and <em>I. yadera</em> and <em>I. sarojamma</em> from south of the Palghat gap; and (iv) a key to the genera and species in the family Ranixalidae.</p><div> </div> |
