Fig. 11

Diagnosis

The new species is similar to H. bohemicus Miller & Buchar, 1977 , H. concertor (Simon, 1878) , H. securifer Bosmans & Abrous, 2018 , H. pseudosignifer Marusik, Hippa & Koponen, 1996 and H. aenus Thaler, 1984 by having a relatively thin embolic apophysis (Ea) with smooth surface/edges and by being over 2.5 times as long as wide but differs from them by having a prolateral bulge on the bulb (Bb, Fig. 11B, E ), and by the shape of the tibial apophysis, relatively sharp and straight (vs with indentations or sharper).

Etymology

The specific epithet is a noun in apposition and refers to the ancient group of Iranian people who inhabited an area known as Media between western and northern Iran.
