At home at least: the taxonomic position of some north African species (Pulmonata, ).

In order to clarify the systematic position of Letourneux in Letourneux & Bourguignat, 1887, and Letourneux & Bourguignat, 1887, a comprehensive approach using morphological and molecular methods is presented. The investigation of the genital organs of both species showed that they belong to the genus Monterosato, 1892 with two very small dart sacs and a few tubiform glandulae mucosae. In our phylogenetic analysis using the mitochondrial markers COI, 16S and the nuclear cluster 5.8-ITS2-28S, the results of the anatomical research were confirmed. Thus, the genus Pallary, 1919, which is based on , becomes a junior synonym of . A review of the genus-level taxa Brandt, 1959, and Brandt, 1959, showed that these should also be considered as synonyms of . A third species, Bourguignat, 1863 from Algeria was found to be closely related to based on its shell morphology. A map showing the distribution of the three species treated is supplied.
