gen. n.

Diagnosis.

Shell elongated conical. Penis simple, broad at the basis and tapered at the distal end, with a black pigmentation mark. The tentacles are cylindrical.

Type species.

Sarkia sarabensis sp. n.

Etymology.

Named after the region where the species was collected.

Differential diagnosis.

The genus seems to be closely related to Pseudamnicola (in the following, in parentheses), but theunique morphology of the penis, broad at the basis and tapered at the distal end (Figs 10b–c), with a black pigmentation mark (vs. broad and elongated triangular penis), and the presence of broad cylindrical tentacles (slim cylindrical tentacles) will separate the new genus from Pseudamnicola.
