Remarks: The redescription of specimens from the type series of P. zagrosiensis demonstrates that the population from Abe Sarabe Sefid agrees well with P. alborziensis. The only differences are found in the higher diameter of eggs (> 170 µm vs. <140 µm in P. alborziensis), and in the relatively shorter gnathosoma (L/ W 1.5 –1.7 vs. 2.0– 2.3 in P. alborziensis). According to Gerecke (1999) the shape of gnathosoma in ventral view (expressed as L/W ratio) is extremely variable and therefore is not suitable for species determination in the eximia species group. In the L/W ratio of the gnathosoma considerably overlaps with the values found in populations of P. caucasica from Vladicaucasus (SMF 4109, 4110; see Gerecke, 1996a). These populations differ from typical P. caucasica populations in the extremely flattened CAc (L/ W 1.0 –1.1), a more shorter gnathosoma (L/ H 1.5), and a slender chelicera (ratio L/H 4.8). In view of the generally homogeneous morphology of the gnathosoma in all investigated populations from a wider geographic range, and of overlapping of their distribution patterns, P. zagrosiensis and P. alborziensis are at best regarded as separate species. The populations from Vladicaucasus described by Gerecke (1996a: SMF 4109, 4110) should be assigned to P. zagrosiensis, in this concept a species with a relatively shorter gnathosoma.

The specimens from Elburs Mountain (1[78/83;78/193 k21]) and Chahar Mahal and Bakhtiari Province (IR29) are in agreement with the specimens from the type series. The only difference is found in the more flattened CAc (L/ W 1.0 –1.1). In view of the good agreement in other measurements this difference are most probably age­depending and/or due to geographical variability.

Distribution: Caucasus Mt. (Vladicaucasus), Iran.
