Using a time-calibrated multi-gene phylogeny, we analyze the tempo of diversification in thecontextof Ecological opportunity past climate and geography to identify historical drivers of current patterns of diversity and distribution. Molecular Diversification dating suggests that the diversification was seeded by migration across a land-bridge connection from India duringa Molecular dating period of climatic cooling and drying, the Oi-1 glacial maximum around the Eocene-Oligocene boundary. Lineage- Speciation through-time plots suggest a gradual and constant rate of diversification, beginning in the Oligocene and extending through the late Miocene and early Pliocene with a slight burst in the Pleistocene. -

Patterns of reproductive-mode evolution in doi:10.1111/zsc.12121 Old World tree frogs (Anura, Rhacophoridae). —Zoologica Scripta, 00, 000–000. The Old World tree frogs (Anura: Rhacophoridae), with 387 species, display a remarkable diversity of reproductive modes – aquatic breeding, terrestrial gel nesting, terrestrial foam nesting and terrestrial direct development. The evolution of these modes has until now remained poorly studied in the context of recent phylogenies for the clade. Here, we use newly obtained DNA sequences from three nuclear and two mitochondrial gene fragments, together with previously published sequence data, to generate a well-resolved phylogeny from which we determine major patterns of reproductive-mode evolution. We show that basal rhacophorids have fully aquatic eggs and larvae. Bayesian ancestral-state reconstruc- tions suggest that terrestrial gel-encapsulated eggs, with early stages of larval development completed within the egg outside of water, are an intermediate stage in the evolution of ter- restrial direct development and foam nesting. The ancestral forms of almost all currently recognized genera (except the fully aquatic basal forms) have a high likelihood of being ter- restrial gel nesters. Direct development and foam nesting each appear to have evolved at least twice within Rhacophoridae, suggesting that reproductive modes are labile and may arise multiple times independently. -

Seven New Species of Night Frogs (Anura, Nyctibatrachidae) from the Western Ghats Biodiversity Hotspot of India, with Remarkably High Diversity of Diminutive Forms
Seven new species of Night Frogs (Anura, Nyctibatrachidae) from the Western Ghats Biodiversity Hotspot of India, with remarkably high diversity of diminutive forms Sonali Garg1, Robin Suyesh1, Sandeep Sukesan2 and SD Biju1 1 Systematics Lab, Department of Environmental Studies, University of Delhi, Delhi, India 2 Kerala Forest Department, Periyar Tiger Reserve, Kerala, India ABSTRACT The Night Frog genus Nyctibatrachus (Family Nyctibatrachidae) represents an endemic anuran lineage of the Western Ghats Biodiversity Hotspot, India. Until now, it included 28 recognised species, of which more than half were described recently over the last five years. Our amphibian explorations have further revealed the presence of undescribed species of Nights Frogs in the southern Western Ghats. Based on integrated molecular, morphological and bioacoustic evidence, seven new species are formally described here as Nyctibatrachus athirappillyensis sp. nov., Nyctibatrachus manalari sp. nov., Nyctibatrachus pulivijayani sp. nov., Nyctibatrachus radcliffei sp. nov., Nyctibatrachus robinmoorei sp. nov., Nyctibatrachus sabarimalai sp. nov. and Nyctibatrachus webilla sp. nov., thereby bringing the total number of valid Nyctibatrachus species to 35 and increasing the former diversity estimates by a quarter. Detailed morphological descriptions, comparisons with other members of the genus, natural history notes, and genetic relationships inferred from phylogenetic analyses of a mitochondrial dataset are presented for all the new species. Additionally, characteristics of male advertisement calls are described for four new and three previously known species. Among the new species, six are currently known to be geographically restricted to low and mid elevation Submitted 6 October 2016 regions south of Palghat gap in the states of Kerala and Tamil Nadu, and one is Accepted 20 January 2017 probably endemic to high-elevation mountain streams slightly northward of the gap in Published 21 February 2017 Tamil Nadu. -

The Discovery of Five New Species of Vine Snakes in India 16 November 2020
The discovery of five new species of vine snakes in India 16 November 2020 discover that the common green vine snake (Ahaetulla nasuta) in India was a complex of several species. They found four distinct small- bodied and short-nosed species: the Northern Western Ghats vine snake (Ahaetulla borealis), Farnsworth's vine snake (Ahaetulla farnsworthi), Malabar vine snake (Ahaetulla malabarica) and Wall's vine snake (Ahaetulla isabellina) in the Western Ghats rainforests alone. These species were superficially similar in their morphology but separated by geographic (or ecological) barriers. Another morphologically distinct and much larger species, the long-nosed vine snake (Ahaetulla oxyrhyncha), was distributed in the lowlands and Ahaetulla farnsworthi.
