Montenegrina is an obligate rock-dwelling door-snail genus, associated with habitats of limestone outcrops. The geographic range of Montenegrina includes the coastal regions of Montenegro south of the Bay of Kotor, Albania, western Macedonia, and northwestern Greece. In geographical terms it extends from the southernmost parts of the Dinaric Mountains to the northern part of the Pindos Mountains, and is separated from the eastern Balkans (Moesia) by the Vardar Basin and the Kosovo Plain. Biogeographically this area can be classified as part of the South Adriatic–Ionian province. The present classification of Montenegrina distinguishes 29 species and 106 subspecies, making it the second most speciose alopiinid genus. This dataset contains known Montenegrina populations that are (or can be) georeferenced in a reliable way. Reference specimens/lots of this distribution dataset are found in the following public collections: Hungarian Natural History Museum, Budapest (HNHM), Munkácsy Mihály Museum, Békéscsaba (MMM), Natural History Museum, Vienna (NHMW), Natural History Museum Bern (NMBE), Naturmuseum Senckenberg, Frankfurt am Main (SMF), Stuttgart State Museum of Natural History, Stuttgart (SMNS), Zoological Museum, Hamburg (ZMH).
