Abstract

Holandriana holandrii (Pfeiffer, 1828) is a freshwater snail, widespread in south-eastern Europe. It belongs to the family Melanopsidae which dominated the Lake Pannon by the number of species and their abundance during the late Miocene and Pliocene. The aim of this research was to determine phylogenetic and phylogeographic relationships of populations of this species based on the analysis of two genetic markers, mitochondrial genes COI and 16S rRNA. Phylogenetic relationships were reconstructed using different phylogenetic methods for each gene region individually as well as for concatenated sets of sequences. Molecular phylogenetic analyses established the existance of three geographically and genetically separated groups and two subgroups. The obtained values of genetic divergence between and within the groups indicate relatively young evolutionary lines which have separated during the Pleistocene.
