Abstract

We describe a new species of small diurnal frog of the genus Gephyromantis from Mahasoa, a fragment of mid-altitude rainforest in the northern central east of Madagascar, located to the north east of Lake Alaotra. Analysis of DNA sequences of the mitochondrial 16S rRNA and cytochrome b genes and of the nuclear Rag 1 gene indicate that Gephyromantis mafy sp. nov. is closely related to G. eiselti and G. thelenae, that it is genetically distinct and when compared with the genetic diversity of all species in the genus shows genetic differences similar to other pairs of species. These three species are morphologically almost indistinguishable but the new species differs by a relevant and consistent genetic divergence in all markers studied, and by its advertisement calls composed of note series. The call is intermediate between G. eiselti and G. thelenae, showing shorter note duration and higher repetition rate than in G. thelenae and slightly longer note duration but lower repetition rate than in G. eiselti. The new species is known only from Mahasoa forest but due to its secretive habits and cryptic morphology, we assume that it is more widespread in the mid-altitude rainforests east and north of Lake Alaotra that so far have been very poorly surveyed. We propose a Red List status of Data Deficient for the new species. Copyright © 2012 · Magnolia Press.
