Type material.

Holotype ♂ (NHMW), Iran: Kerman Province: 41 km SE of Sirjan, 18.4.1972 (G. Pretzmann).

Etymology.

The specific epithet is a noun in apposition, referring to a historical region that approximately corresponds to the modern Iranian province of Kerman, where the type locality of the new species is situated.

Diagnosis.

The new species differs from the related P. persicus sp. nov. by the more distal position of the base of the "embolic stalk" (Es) and wider stalk with sharply pointed tip (vs more proximal, thinner and without sharply pointed tip; cf. Fig. 16E and A ) and also by having wider than long palpal tibia (vs as wide as long). It is most similar to P. cf. sogdianus from Azerbaijan illustrated by Marusik and Guseinov (2003). Both have a sharply pointed embolic stalk (Es), but in the new species this originates from the distal half of the bulb (vs proximal half).

Description.

Male. Habitus as in Figures 13A , 14A . Total length 5.50. Carapace 2.65 long, 1.92 wide. Eye sizes: AME: 0.17, ALE: 0.08, PME: 0.07, PLE: 0.10. Carapace, labium, chelicera, maxilla and sternum dark reddish, coated with white setae. Leg I dark orange, legs II-IV yellowish-brown, without annulations. Metatarsus I and metatarsi and tarsi II-IV with a distinct ventral hair tuft. Abdomen cream-colored, with scattered long dark setae and a ventral scutum, two long diagonal and two dot-like scutula (Fig. 14B ). Spinnerets unicolourous. Measurements of legs: I: 6.05 (1.90, 1.58, 1.34, 0.58, 0.65), II: 4.59 (1.26, 0.90, 1.12, 0.74, 0.57), III: 4.05 (1.16, 0.80, 0.87, 0.76, 0.46), IV: 5.18 (1.35, 0.86, 1.28, 1.08, 0.61).

Palp as in Figures 15A-C , 16E-G ; tibia swollen, ca 1.1 times wider than long, wider than bulb; cymbium 1.5 times longer than tibia; embolic stalk (Es) originates in anterior half, stalk tapering, tip sharply pointed.

Female. Unknown.

Distribution.

Known only from the type locality in Kerman Province, southern Iran.
