Spariolenus zagros spec. nov.

Figs 27–38

Type material. Holotype: male, IRAN: Kermanshah Province: Kermanshah, Kenesht cave, Kenesht valley, North of Kermanshah plain, central western Zagros Mountains, Iran. N 34˚29', E 47˚09', altitude 1900 m, 3 August 1973, A. Senglet (MHNG).

Paratypes: 13, 4Ƥ, IRAN: Kermanshah Province: with same data as for holotype (3 Ƥ MHNG, 1 3 1 Ƥ SMF).

Etymology. The species name refers to Zagros, the great mountain chain in western and central Iran, which orogeny might be associated with the speciation of the current Spariolenus species in Iran; noun in opposition.

Diagnosis. Males can be easily recognised by bifurcated embolus tip (Figs 28, 30). Embolus and conductor longer than in S. tigris but shorter than in S. iranomaximus spec. nov. Female epigyne similar to those of S. manesht spec. nov. (Fig. 20) but differing from it by two separate eyebrow-like ridges at anterior side of each copulatory openings (Fig. 31).

Colouration [inferred from specimens in ethanol]. Pale yellowish brown with indistinct marking dorsally.
