Same but different: towards taxonomic status of Myotis ater (Chiroptera: Vespertilionidae) from the mainland Asia

Abstract

Abstract Myotis muricola species group, being common and widespread across South-East Asia and Australasia, is highly complicated from a taxonomy point, and a combined use of different methods is required to solve subjects of its phylogeny, taxonomy and species delimitation. We try to use nuclear DNA for clarification of the taxonomic position and status of the Moluccan whiskered bat, Myotis ater, and in particular its population from mainland Asia mainland Asia. Following our results, individual nuclear markers showed weak phylogenetic signal and commonly provide controversial and low-supported topologies. The combined analysis of several nuclear genes gives a tree topology similar to the mitochondrial one, but with greatly smaller distances. Mitochondrial data, as well as morphometric data, show a separation of M. ater from M. muricola and, at the same time, a similar level of diversification between island and continental populations of M. ater. Unfortunately, nuDNA data at our disposal is not enough to come to reliable conclusions, but we may assume that continental Asia is inhabited by an undescribed taxon related to M. ater.
