Abstract

We describe a new cryptic species of Phrynoglossus from Chattogram Division, Bangladesh based on an integrative taxonomic analysis based on morphology, phylogenetics, and bioacoustics which unambiguously support the placement of the species in the genus Phrynoglossus. We also present a compilation of published morphological characters for all twelve Phrynoglossus species and two species of Occidozyga as well as comments on taxonomy, morphology, and geographic distribution for the two genera. The new species is found to be most morphologically similar to P. martensii, however a provided set of character states visibly differentiates these two species. Finally, habitat for Phrynoglossus swanbornorum sp. nov. is highly fragmented and faces imminent threats from development and agriculture, and although it is confirmed to occur within government protected areas in the southeastern region of Bangladesh, few wildlife regulations are enforced within them. Thus, following IUCN criteria, we consider the new species as Endangered based on criteria B1ab(i,ii,iii,iv) + 2ab(i,ii,iii,iv).
