Diagnosis

The new species is similar to Z. eugeni Kovblyuk, 2009 and Z. longipes (L. Koch, 1866) by having a similarly shaped atrium and anterior hood. It differs from Z. eugeni by having anterior hoods that are 1.3 times as wide as the atrium (vs almost 2 times). It differs from Z. longipes by the longer lateral margins, ⅔ as long as atrium (vs ½) and the diverging copulatory ducts adjoining to receptacles (vs parallel).

Etymology

The specific epithet is an adjective and refers to Hyrcanian region, in which the type locality of the new species is located.

Type material

Holotype IRAN • ♀; Mazandaran Province, 20 km north of Chalus; May 2015; D. Kasatkin leg.; MHNG.
