In the family Rhinolophidae, the members of the trifoliatus clade are easily recognisable by a unique noseleaf structure and a fluffy fur. Within this group, Rhinolophus luctus is the largest species with currently six recognized subspecies, distributed from India to Bali. We investigated genetic (karyotype, mitochondrial DNA sequence) and morphological characters from a Peninsular Malaysian sample. Although the diploid number was 2n = 32 in all specimens, karyotype analysis revealed two largely different chromosomal sets, with a Y-autosome translocation present only in one of the taxa. Morphological examination revealed differences concerning size of the baculum and length of the lower toothrow. Based on these results, a new species is described and the former subspecies distributed on the Malayan Peninsula, Rhinolophus luctus morio, is elevated to species rank, Rhinolophus morio.

In contrast to the Eastern Palaearctic region a high degree of cryptic diversity was discovered among temperate bats of the Western Palaearctic region in the last ten years. Climatic oscillations caused severe changes in the distribution of species throughout the Palaearctic region during the Pleistocene. Exploring multiple taxa can help to understand general evolutionary differentiation processes. In the present study genetic variation within and among 94 Mongolian vespertilionid bats of six genera (Hypsugo, Eptesicus, Vespertilio, Myotis, Plecotus, and Nyctalus) was screened by sequencing a 798 bp fragment of the mitochondrial ND1 gene and then subsequently compared with those of Western Palaearctic taxa. This allowed first insights in the differentiation among a wide range of bats across the Palaearctic region. A total of 16 distinct mitochondrial lineages were found in Mongolia. Thirteen lineages differed by at least five percent sequence divergence from Western Palaearctic species. Only three lineages (Eptesicus nilssonii, Vespertilio murinus, and Nyctalus noctula) showed lower divergence values. Our data demonstrate a substantial differentiation between most Western and Eastern Palaearctic vespertilionid bats. Estimations of divergence times showed that most divergence appeared prior to the Pleistocene, but current distributions of bats were most likely shaped by the usage of multiple refugia during glaciations.

Since its description in 2001 Alcathoe's myotis (Myotis alcathoe) was recorded from several locations across Europe. Here we describe the first records of this species from Germany, Poland, Albania, and from the European part of Turkey, including the northernmost locality in central Germany (51°23′N, 11°01′E). Compilation of all up-to-date records shows that M. alcathoe has a wide European distribution although it seems to be rare at most places. The habitats where the bat was recorded are natural, moist and deciduous forests with old trees and water streams as can be found, for example, in canyons or forests of alluvial origin. Such habitats suggest that the species probably has a more continuous and wider distribution than currently known and might be expected to occur even further to the North.
