“…Ranixalid species have often been misidentified (e.g., [10, 11, 28, 29, 32, 58, 60–63]) due to their highly conserved external morphology resulting in taxonomic confusions and uncertainties. Dahanukar et al .…”

“…These studies suggested that many of the presently recognized species are likely to be complexes of several cryptic species, following which six new Indirana species have been described [10–12]. Even though a considerable amount of molecular data from populations across the Western Ghats became available in the recent years [10, 11, 28–30], species identity in most cases remained doubtful due to various persistent sources of confusion, including the status and unavailability of some type specimens [31]. A taxonomic review was provided by Nair et al .…”

The monotypic anuran family Ranixalidae is endemic to India, with a predominant distribution in the Western Ghats, a region that is home to several unique amphibian lineages. It is also one of the three ancient anuran families that diversified on the Indian landmass long before several larger radiations of extant frogs in this region. In recent years, ranixalids have been subjected to DNA barcoding and systematic studies. Nearly half of the presently recognized species in this family have been described over the last three years, along with recognition of a new genus to accommodate three previously known members. Our surveys in the Western Ghats further suggest the presence of undescribed diversity in this group, thereby increasing former diversity estimates. Based on rapid genetic identification using a mitochondrial gene, followed by phylogenetic analyses with an additional nuclear gene and detailed morphological studies including examination of museum specimens, new collections, and available literature, here we describe two new species belonging to the genus Indirana from the Western Ghats states of Karnataka and Kerala. We also provide new genetic and morphological data along with confirmed distribution records for all the species known prior to this study. This updated systematic revision of family Ranixalidae will facilitate future studies and provide vital information for conservation assessment of these relic frogs.

“…To augment existing DNA sequence data from published literature [20][21][22][23], we selected fortyfour specimens of the genus Indirana and Walkerana in this study. Samples were selected in such a way that they represented potentially isolated populations across the entire range of the Western Ghats.…”

“…The DNA sequences obtained from individuals (n = 44) were aligned using MUSCLE in the R programming environment v 3.6.1 [27,28]. To the above set of forty-four 16S sequences, we added available 16S sequences from recent studies [20][21][22][23]. The final alignment of 16S rRNA gene sequences was 483bp long and consisted of a total of 92 individuals which included all individuals of Indirana and Walkerana that were sequenced by Nair et al [24], Padhye et al [20], Modak et al [21], Dahanukar et al [22] and Garg and Biju [23].…”

“…Indirana, an endemic genus in the Western Ghats, belongs to one of the ancient clades of frogs that originated in the Gondwana and diversified in-situ [19]. Recent studies have suggested the existence of genetically divergent lineages, including new species and as well as a new genus-Walkerana-within this clade [20][21][22][23]. An earlier study by Nair et al [24] brought to light the occurrence of cryptic diversity in the genus Indirana in the Western Ghats; however, this has not been formally tested along multiple axes such as geography, morphology and genetics.…”

Determining levels of cryptic diversity within the endemic frog genera, Indirana and Walkerana, of the Western Ghats, India

A large number of species in the tropics are awaiting discovery, many due to their cryptic morphology ie. lack of discernable morphological difference. We explored the presence of cryptic lineages within the frog genera, Indirana and Walkerana, which are endemic to the Western Ghats of Peninsular India. By reconstructing a phylogeny using 5 genes and robust geographic sampling, we delimited 19 lineages along a population-species continuum, using multiple criteria including haplotype clusters, genetic distance, morphological distinctness, and geographical separation. Of these 19 lineages, 14 belonged to the genus Indirana and 5 to the genus Walkerana. Divergence dating analyses revealed that the clade comprising Indirana and Walkerana began diversifying around 71 mya and the most recent common ancestor of Indirana and Walkerana split around 43 mya. We tested for the presence of cryptic lineages by examining the relationship between genetic and morphological divergence among related pairs within a pool of 15 lineages. The pairs showed strong morphological conservatism across varying levels of genetic divergence. Our results highlight the prevalence of morphologically cryptic lineages in these ancient endemic clades of the Western Ghats. This emphasizes the significance of other axes, such as geography, in species delimitation. With increasing threats to amphibian habitats, it is imperative that cryptic lineages are identified so that appropriate conservation measures can be implemented.
