ETYMOLOGY. Named after the province of occurrence.

DIAGNOSIS (♂ ♀). Total length of adults 33–40 mm. Trichobothrium d 2 at pedipalp femur dorsal surface absent or reduced. Moderate to strong tibial spurs present on third and fourth legs. Pectinal teeth number 17–19 in both sexes. Movable finger of pedipalps with 7–8 rows of denticles, 6–8 ID and 4–6 OD. Dorsal carinae on pedipalp patella present and smooth. Metasoma V dorsal surface mesially smooth. Metasoma I–II with 10 carinae, metasoma III with 8 carinae, metasoma IV–V with four granulated carinae present. Ventral carinae of metasoma I–III consist of a row of large granules, at least in the male. Metasoma IV–V ventrally and laterally with developed punctation; spaces among punctae smooth; metasoma II–III ventrally and laterally granulated and bumpy with punctation reduced. Sternite VII finely granulate, with granulate carinae developed. Pedipalp, metasoma and telson very sparsely hirsute, rather glabrous. Tarsomere I of legs with bristlecombs composed of 5–7 long bristles. Ratio length/width of metasoma V in males 1.33.

DESCRIPTION. Total length of adults 33–40 mm in both sexes. Measurements of the carapace, telson, segments of the metasoma and segments of the pedipalps are given in Table 2 . For habitus, see Figs. 41–44 .

Coloration ( Figs. 41–44 ). Carapace, tergites, and metasoma brown to black. Pedipalps and legs yellow, yellowish brown, or black. Sternite VII brown or black, other sternites yellowish or reddish brown to black, with yellow median area in posterior margin of sternites IV–VI reduced or absent. Telson reddish brown.

Mesosoma and carapace ( Figs. 51–54 , 65–66 ). Mesosoma with a median carina and is roughly granulated in middle but laterally smooth with several fine granules in males; females can have roughly granulated whole tergites. Carapace without carinae, roughly granulated posteriorly and laterally, interocular triangle is smooth. The seventh sternite is finely granulated and with four wide granulated carinae, the other sternites are rather smooth, sparsely granulated mainly in anterior parts. Pectinal teeth number 19 in male and 17–19 in females.

Metasoma and telson ( Figs. 45–50 , 63–64 , 67 , 223 ). Metasoma I–II with 10 granulated carinae. Metasoma III–V lack lateral carinae, ventromedian carinae present on metasoma I–III, ventrolateral carinae present on all metasomal segments, dorsolateral carinae present on metasoma I–IV and reduced to absent on metasoma V. Ventral carinae of metasoma I–III consist of a row of large granules. Metasoma I granulated laterally, other segments are laterally smooth; granulation absent on dorsal surfaces of all metasomal segments except several fine granules on metasoma V dorsal mesially. Punctation on metasoma IV–V is ventrally and laterally developed, spaces among punctae are smooth. The entire metasoma and telson glabrous; short, thin setae might issue from some punctae. Telson shallowly punctate and lacks granules.

Pedipalps ( Figs. 68–87 ). Trichobothrium d 2 on the dorsal surface of pedipalp femur is absent or reduced; trichobothrium e 1 is situated in level with d 4. Femur of pedipalp with five granulate carinae. Patella with seven smooth carinae; the chela with smooth carinae which may be discernible throughout the length of the fixed finger. The entire pedipalp only very sparsely hirsute. Movable fingers with 7–8 rows of denticles, 6–8 ID and 4–6 OD.

Legs ( Figs. 55–62 ). Moderate to strong tibial spurs present on third and fourth legs. Femur with four partly granulated carinae; patella with five rather smooth carinae; tibia smooth. Patella with only a few bristles. Tibia with bristles on the outer side of legs I–II. Tarsomere I of first to third legs with bristlecombs composed of 5–7 bristles long in both sexes, fourth legs lack bristlecombs. Tarsomeres I–II of all legs with two rather irregular rows of bristles.

Measurements. See Table 2 .

AFFINITIES. The described features distinguish O. kermanensis sp. n. from all other species of the genus. They are recounted in the key below. O. kermanensis sp. n. is similar to O. zagrosensis Kovařík, 2004 . These two species can be differentiated according to the metasoma morphology. Metasomal segments II–III are laterally smooth and punctate with lateral carinae absent or smooth in O. zagrosensis versus granulated and bumpy with lateral carinae present and granulated at least on metasoma II in O. kermanensis sp. n. ( Figs. 45 and 48 ). Pedipalp movable finger has 4–6 OD outside of MD row in O. kermanensis sp. n. and 8 OD in O. zagrosensis .
