Genus Zeteana gen. nov.

Diagnosis. Shell elongated conical with a large ovoid aperture. The lower edge of the aperture moved forwards and the outer margin is sinuated from lateral view. Surface slightly ribbed, with broad ribs and thin interspaces. The animal is whitish, without eyes. The penis is broad at the base and pointed at the top and the sperm duct takes a lateral course. Anatomy of females is unknown.

Type species. Zeteana ljiljanae n. sp.

Etymology. Named after Zeta River.

Differential diagnosis. Conchologically, snails of the new genus are similar to Paladilhiopsis Pavlović (1913) sensu Radoman , but species of this genus have a rectangular broad penis which is attenuated at the top. However the shell surface of the latter genus is smooth and not ribbed ( Radoman 1983).

Shells of Plagigeyeria Tomlin, 1930 are ribbed but the new genus clearly differs by the shape of the shell (see under Plagigeyeria lukai n. sp.), as well as by the shape of the ribs, which are broad in Zeteana n. gen. vs. thin and sharp in Plagigeyeria . Moreover, the penis in Plagigeyeria is awl-like ( Radoman 1983: fig. 55) and more slender compared with Zeteana n. gen. Species of the genus Lanzaia Brusina, 1906 , in addition to awl-like penis, differs in having rare and strong axial and weaker spiral sculptures ( Radoman 1983).

Distribution. The genus is endemic to Central Montenegro and includes the only species: Zeteana ljiljanae n. sp. from its type locality only. The diagnostic characters of the new species coincide with those of the new genus.
