Diagnosis

In the shape of the distally spiraled embolus, the holotype of Raveniola marusiki sp. nov. resembles males of R. vonwicki and R. zaitzevi, but differ from them, as well as from other species of the same group, by the unique shape of its pectinate embolic keel (Fig. 191).

Etymology

The specific epithet is given in honour of our friend and colleague Yuri Marusik for his immense contribution to the study of the spider fauna of Turkey and Iran.
