4.7 | Phylogenetic position and taxonomy of A. limnophilus View in CoL
A lacustrine vole A. limnophilus inhabits wet habitats in extra dry surroundings from the Qaidam to Gobi Desert. According to Musser and Carleton (2005), the junior synonyms for this name are A. flaviventris Satunin, 1903 ; A. malcolmi Thomas, 1911 ; and A. malygini Courant et al. 1999 . Representatives of these nominal taxa were never checked for genetic proximity. We had no data on A. malcolmi ; however, we analysed cytb sequences derived from type specimens of A. limnophilus and A. flaviventris . The main study was conducted on the basis of specimens of A. l. malygini from Mongolia. Our results confirmed that limnophilus , flaviventris and malygini belong to the same clade, thus supporting the current taxonomic concept. We found some polymorphism in cytb sequences of A. limnophilus . This result is expected, as we previously found a morphological difference between A. l. malygini and A. l. limnophilus ( Lissovsky & Obolenskaya, 2011). Although we found taxonomical integrity of A. limnophilus , it is premature to discuss taxonomy, unless a type specimen of A. malcolmi is evaluated.
The topology of mtDNA-based trees in both previous ( Bannikova et al., 2010) and present (Figure 2; Fig. S1) studies contradict our nuclear DNA-based results ( Figure 3 View FIGURE 3 ). Both hypotheses are supported by similar bpp values. However, our JML study revealed that the position of A. limnophilus on the mitochondrial tree could be successfully explained by incomplete lineage sorting, if the nuclear data set reflects the true phylogenetic pattern. Thus, there are no unresolved conflicts between both sets of genes; we can hypothesise that A. limnophilus is a sister to short-tailed voles. This hypothesis is indirectly supported by morphological similarity of the voles in question ( Lissovsky & Obolenskaya, 2011).
