Diagnosis

In the structure of the palpal organ this species resembles Raveniola turcica sp. nov., but differs from the latter by the presence of a small triangular embolic keel vestige and by the basal bend being confined to the median part of a shorter embolus (Fig. 183; cf. Figs 185–186).

Etymology

The specific epithet is the Turkish name for Anatolia; the type locality of this species lies in the East Anatolia region of Turkey.

Female

Unknown.

Variation

Carapace length in males varies from 4.22 to 5.04. The size and shape of the embolic keel vestige in all paratype males do not differ from those in the holotypic male.

Ecology

The type series, which includes only males, was collected with pitfall traps in an open rocky biotope sparsely covered with low Juniperus trees and shrubs.

Distribution

Known only from the type locality. See Fig. 221.
