Taxonomic revision of the rock-dwelling door snail genus Montenegrina Boettger, 1877 (Mollusca, Gastropoda, Clausiliidae) Author Feher, Zoltan Author Szekeres, Miklos text ZooKeys 2016 599 1 137 http://dx.doi.org/10.3897/zookeys.599.8168 journal article http://dx.doi.org/10.3897/zookeys.599.8168 1313-2970-599-1 8BEE967F7C6946928210A440AD8E2018 Taxon classification Animalia Stylommatophora Clausiliidae Montenegrina attemsi (Wagner, 1914) Diagnosis. Shell small, slender, light yellowish-corneous. All whorls smooth. Peristome attached, ovoid to angular, with somewhat swollen margin. Lamellae superior and spiralis overlap. In front view lamella inferior hidden or weakly emerged, subcolumellaris broadly-bent. Lunella dorsolateral to lateral, diffuse, not connected to the basalis. Subclaustralis absent or residual, sulcalis present. Anterior plica superior not connected to the lunella complex. Clausilium plate only barely visible through the aperture. Differs from similar-looking Montenegrina janinensis by the smaller, more elongate, entirely smooth shell, as well as the less emerged lamella inferior.
