Species delimitation methods put into taxonomic practice: two new Madascincus species formerly allocated to historical species names (Squamata, Scincidae)

In a previous study, Miralles and Vences (2013) compared seven different methods of species delimitation applied to the genus Madascincus. While focusing on methodological aspects their study involved an extensive data set of multilocus DNA sequences and of comparative morphology. On this basis they emphasized the need of revising the taxonomy of Madascincus, and revealed the existence of at least two well-supported candidate species. The present paper provides formal descriptions of these two taxa: (1) M. miafina sp. n., a species from dry areas of northern Madagascar, morphologically very similar to M. polleni (although both species are not retrieved as sister taxa), and (2) M. pyrurus sp. n., a montane species occurring >1500 m above sea level, endemic to the central highlands of Madagascar (Ibity and Itremo Massifs). Phylogenetically, M. pyrurus is the sister species of M. igneocaudatus, a taxon restricted to the dry littoral regions of the south and south-west of Madagascar in lowlands
