Male

Unknown.

Etymology

The species is named after the type locality, Emirdağı mountains , Afyonkarahisar, Turkey .

Remarks

This species is close to R. eυidus Fan and Yin, 2000 in having more than two pairs of setae on interscutal membrane, the same setation on leg femur IV and on palpfemur, but it can be recognized by following features: (1) dorsal shields not reduced, interscutal membrane with three pairs of setae (d 1, e 1, and f 1); (2) genu II with five setae; (3) opisthosomal shield with three pairs of setae; (4) setae h 1 well behind anterior margin on opisthosomal shield; (5) interscutal membrane with one pair of lyrifissures (im).
