Type.

Holotype ♂ (AZMI), IRAN: Ilam Province: Mehran County, 2001 (F. Mozaffarian).

Etymology.

This species is named after the Ukrainian arachnologist Mykola Kovblyuk in recognition of his contributions to the taxonomy of gnaphosid spiders.

Diagnosis.

The new species is most similar to P. dalmasi by lacking a stylus on the embolus, the similar shape of the tegular apophysis and the tibial apophysis with a spine like tip (cf. Figs 2 e–g and figs 71-73 in Levy 1995). The two species can be separated by the thinner tip of the conductor and the tegular apophysis which is longer than wide in the new species, vs. wider than long in P. dalmasi (cf. Fig. 2e and figs 71-73 in Levy 1995).

Description. Male. Total length 6.7. Carapace 2.8 long, 2.25 wide. Eye sizes and interdistances: AME: 0.21, ALE: 0.17, PME: 0.24, PLE: 0.20, PME–PME: 0.05. Carapace, sternum, labium, chelicerae, and maxillae light brown without any distinct patterns, with darkening in the ocular area. Abdomen light grey with distinct pale cardiac mark with three pairs of dots on either side. Legs the same colour as the carapace and without annulations. Scopula on metatarsi and tarsi indistinct. Tarsi of legs I-II (legs III and IV missing) with cuticular cracks (pseudosegmented). Leg measurements: I: 12.1 (3.1, 1.25, 2.5, 3.2, 2.05), II: 12.55 (2.95, 1.2, 2.35, 3.65, 2.4), III: absent, IV: absent.

Palp as in Figs 2 c–g; patella almost as long as tibia, patella+tibia as long as cymbium; tibial apophysis with one arm, posterior part rounded, anterior part with a spine like tip; tegular apophysis (Ta) longer than wide with retrolateral lobe and large base; conductor (Co) large, tip rounded; embolus (Em) simple and without a stylus.

Female. Unknown.
