  • Title
    Indirana salelkari, a new species of leaping frog (Anura: Ranixalidae) from Western Ghats of Goa, India
    Type
    Journal Article
    Description
    Indirana salelkari, a new species of leaping frog, is described from Netravali, Goa, India.  The species can be distinguished from its congeners by a combination of morphological characters, viz., head longer than wide, narrow and deep buccal cavity, vomerine teeth large and acutely placed close to each other, oval choanae, distinct canthus rostralis, first finger longer than or equal to second, presence of double outer palmer tubercles, elongated inner metatarsal tubercle, moderate webbing, discs of fingers and toes with crescentic deep marginal grooves restricted only to the anterior side of the discs, dorsal skin with glandular folds but without warts, ventral skin granular with some mottling on throat and, palms and soles dark brown.  Indirana salelkari differs from its sister taxa, I. chiravasi, in the placement and structure of vomerine teeth and choanae.  The new species is genetically distinct from I. chiravasi, with a genetic distance of 3.8% for the 16S rRNA gene.  We also provide phylogentic placement of Indirana salelkari based on mitochondrial 12S and 16S ribosomal genes and nuclear rhodopsin gene along with molecular clock analysis, which further confirms its genetic distinctness from other related taxa.

  • Title
    Hydrophylax bahuvistara, a new species of fungoid frog (Amphibia: Ranidae) from peninsular India
    Type
    Journal Article
    Description
    Hydrophylax bahuvistara, a new species of fungoid frog, is described from peninsular India. It can be separated from its congeners based on a combination of characters including wider head, outline of snout in dorsal view truncated, finger and toe tips without lateroventral groove, foot moderately webbed, metatarsals of 4th and 5th toes closely set, outer metatarsal tubercle small, foot length less than or equal to half of snout vent length, dorsal parts of shank without glandular folds and sparse horny spinules, and heels touch each other when the legs are folded at right angles to the body.  Genetically, H. bahuvistara forms a monophyletic group with H. malabaricus as a sister clade separated by a raw distance of 4.0 to 4.5% in the 16s rRNA gene.  Morphometrically, H. bahuvistara forms a significantly different cluster from H. malabaricus and H. gracilis in Discriminant Analysis.
