Montenegrina skipetarica robusta Nordsieck, 2009: 77-78, plate 2, fig. 8.

Diagnosis.

Shell medium to large, brownish-corneous. Very weak and indistinct ribs of the lower whorls become stronger and better defined toward the apex. Weakly inflexed neck has more robust ribs. Basal and peripheral crests weak. Peristome ovoid, mostly attached, with swollen, reflexed margin. Lamellae superior and spiralis overlap. In front view lamella inferior more or less well emerged, broadly-bent subcolumellaris visible. Lunella short and broad, dorsal-dorsolateral to dorsolateral, mostly fused to the basalis. Subclaustralis residual or absent, sulcalis well developed. Anterior plica superior long, often connected to the lunella complex.
