Diagnosis.

Shell small to medium, light corneous. Lower whorls smooth, upper ones indistinctly wrinkled-costate. Neck inflexed, costate. Basal and peripheral crests weak. Peristome attached, ovoid, with simple margin. Lamellae superior and spiralis mostly overlap. In front view lamella inferior more or less well emerged, broadly-bent subcolumellaris occasionally visible. Lunella dorsal, short and broad. Basalis residual, separate from the lunella. Subclaustralis absent, sulcalis well developed. Anterior plica superior mostly not connected to the lunella complex.

Dimensions

(in mm). Hs: 14.5-18.6 (holotype 16.0), Ws: 3.6-4.1.

Type locality.

Greece, Western Macedonia, Portitsa bridge, 4 km SE of Zakas, 625 m.

Type material.

Type locality, leg. Gittenberger, Maassen, 24.v.2001, holotype (RMNH 94949), paratypes (RMNH 82024/28, NMBE 535056/2, SMF 331784/2).

Other material.

Greece, Portitsa Farangi, near Spileo, 39.9965°N, 21.2855°E, leg. ZE, ZF, JG, 22.vi.2013 (HNHM 99595); same locality, leg. ZE, AH, 15.vii.2004 (HNHM 99594).

Distribution.

Western Macedonia (Greece). Known only from its type locality, the gorge of the Venetikos River. Montenegrina hiltrudae dennisi occurs only a few few km farther north, at the slope of the Mt. Orliakas, bordered by the Venetikos Valley (Fig. 20).

Remarks.

Montenegrina hiltrudae maasseni was described by Gittenberger (2002) as a subspecies of Montenegrina janinenis , but its shell morphology suggests a close relationship to Montenegrina hiltrudae dennisi (see: Erőss et al. 2006).
