Fig. 183 ). 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 ). Etymology The specific epithet is a Latinized adjective of “turcia”, the Medieval Latin name for Turkey.
