Zodarion siirtensis spec. nov.

( Figures 23–35 )

Type material. Holotype (KUAM-ZOD-2020/75) ♂, Turkey, Siirt Province, 37°57’05’’N, 41°50’10’’E, elevation 625 m, 20 May 2015, T. Danışman leg., stony field near thicket . Paratypes: 2♂, Diyarbakır Province, Yeniköy , Sil- van, 38°07’21’’N, 41°02’12’’E, elevation 875 m, 19 May 2015, T. Danışman leg., stony field near thicket (KUAM- ZOD-2020/76) .

Etymology. The specific name refers to the type locality.

Diagnosis. Zodarion siirtensis spec. nov. is a member of the spinibarbe group and is similar to Z. hauseri Brignoli, 1984 . The males differ by the complex shape of the median apophysis and the dorsal protrusion of the cymbium.
