Diagnosis

The new species is mostly similar to M. cumensis (Ponomarev, 1979), M. manytchensis (Ponomarev & Tsvetkov, 2006), M. malkini (Platnick & Murphy, 1984) and M. mutabilis (Simon, 1878) in that the M-shaped median ridge is at the middle to upper part of the median plate, while extending further to posterior end in the congeners. It differs from M. cumensis by its long copulatory ducts extending beyond the anterior margin (vs very short and well below the anterior margin) and from the others by the shape of atrium being wider than long (vs longer than wide).

Etymology

The specific epithet is a noun in apposition, referring to the apical ancestor of the Achaemenid dynasty.
