A REASSESSMENT OF THE SYSTEMATIC POSITION OF THE ASIAN RANID FROG Hylorana nicobariensis STOLICZKA, 1870 (AMPHIBIA: ANURA) WITH THE DESCRIPTION OF A NEW GENUS

We reassessed the systematic position of the ranid frog Hylorana (=Hylarana) nicobariensis that, owing to its uncertain phylogenetic position and lack of clear morphological characterisation, has lately been allocated to various Asian and African frog genera such as Rana, Sylvirana, Hylarana, Amnirana, and most recently to Indosylvirana. Based on an integrative approach of both phylogenetic and morphological affinities, we describe a new genus to accommodate Hylorana (=Hylarana) nicobariensis and redescribe the species based on new topotypic material from the Nicobar Islands.
