Montenegrospeum Pesic et Gloer, 2013: a representative of Moitessieriidae?

The paper deals with phylogenetic relationships of recently described Montenegrospeum bogici Pešić et Glöer, 2012 from central Bosnia. The female reproductive system was found to bear two receptacula seminis. Mitochondrial cytochrome oxidase subunit I and nuclear 18S rRNA gene partial sequences were used for the maximum likelihood phylogenetic inference. Morphological and molecular data are congruent: Montenegrospeum does not belong to the Moitessieriidae, and is phylogenetically remote from Bythiospeum; it belongs to the Hydrobiidae, subfamily Sadlerianinae, and its sister taxon is Dalmatinella Radoman, 1973 (bootstrap support 87%).
