Diagnosis

In the structure of its palpal organ this species resembles Raveniola anadolu sp. nov., but differs from it by the absence of any traces of the embolic keel, and in having the basal bend confined to the subapical part of a longer embolus ( Figs 185–186 View Figs 180–188 ; cf. Fig. 183 View Figs 180–188 ). Females of R. turcica sp. nov. have the spermathecae somewhat similar to those of the only known female of R. nana sp. nov., but both are well-distinguishable from each other: in R. turcica sp. nov. the median and lateral receptacles are wide apart, whereas in R. nana sp. nov. they are close to each other (cf. Figs 204–205 View Figs 204–212 ).

Etymology

The specific epithet is a Latinized adjective of “turcia”, the Medieval Latin name for Turkey.
