Platypelis ravus sp. nov. differs from all other known Platypelis and Cophyla species by its small size (17-19 mm snout-vent length) and a combination of other morphological and bioacoustic characters. The new species seems to be most closely related to P. milloti with which it shares the principal colour pattern, but exhibits a yellow rather than red posterior venter. Uncorrected pairwise sequence divergence in a 16S rRNA gene fragment to all other known species of the genus (except P. cowanii for which no genetic data is available) is greater than 6%. We suggest the inclusion of the new species in the IUCN threat category ¡°Data Deficient¡±. %K Microhylidae %K Cophylinae %K Platypelis ravus sp. nov. %K Madagascar %K Marojejy National Park %U http://www.europeanjournaloftaxonomy.eu/index.php/ejt/article/view/92
