abstract = {The phylogeography and population structure of land snails belonging to the Caucasotachea atrolabiata complex in the
Caucasus region was investigated to obtain a better understanding of diversification processes in this biodiversity hotspot.
So far the complex has been classified into three species, C. atrolabiata from the north-western Caucasus, C. calligera
from Transcaucasia and C. intercedens from the eastern Pontus Mountains. Phylogenetic (neighbor-net and neighbor-
joining tree) as well as admixture analyses based on AFLP data showed that the complex consists of two population
clusters corresponding to C. atrolabiata and C. calligera. The populations assigned to C. intercedens in fact represent
hybrids consisting of different proportions of the genomes of C. atrolabiata and C. calligera. There is a broad transition
zone between C. atrolabiata and C. calligera in the Pontic Mountains and a second transition zone in Abkhazia. Because
of evidence for gene flow, it is suggested to classify the two aforementioned taxa as subspecies, namely C. a. atrolabiata
and C. a. calligera. The presence of mitochondrial C. a. atrolabiata haplotypes in Turkey can only be explained by passive
dispersal across the Black Sea. The distribution of C. a. atrolabiata and additional cases of land snails with disjunct
Transpontic distribution patterns cannot be ascribed to a common cause but are results of long distance dispersal events
at different times.}
