 Abstract

The Madagascan endemic subfamily Cophylinae in the family Microhylidae, is an example of a taxonomic group for which much is still to be discovered. Indeed, the cophyline frogs present a large portion of Madagascar’s cryptic and microendemic amphibian diversity, yet they remain understudied. A new red-bellied species of the microhylid frog genus Stumpffia is described from the central plateau of Madagascar. Visual encounter surveys in Ambohitantely and Anjozorobe in 2019 and 2020 identified this previously unknown Stumpffia species, which closely resembles Stumpffiakibomena known from Andasibe in the east. Stumpffialynnaesp. nov. adds another species to the red-bellied species complex, differing from S. kibomena by genetic differentiation in the mitochondrial 16S rRNA gene (3.6–3.9%) and distinct nuclear RAG1 haplotypes, as well as strongly by its advertisement call. The new species is …
