Diagnosis

In the structure of its embolus this species is similar to Raveniola micropa , but differs from the latter by a considerably shorter and narrower proximal part of the embolus ( Fig. 184 View Figs 180–188 ; cf. Fig. 187–188 View Figs 180–188 ).

Female

Unknown.

Variation

Carapace length in males varies from 4.05 to 4.16. The shape of the embolus in the holotype and both paratypic males is practically identical.

Ecology

The type series, containing only males, was collected in an open steppe biotope without trees; the spiders were found hiding under stones.

Distribution

Known only from the type locality. See Fig. 221 View Figure221 .
