The species epithet is a patronym honoring the Italian arachnologist Valerio Vignoli, the collector of two specimens initially identified as O. zagrosensis. DIAGNOSIS (♂ ♀). Total length of adults 29���44 mm. Trichobothrium d 2 at pedipalp femur dorsal surface absent or reduced. Moderate tibial spurs present on third and fourth legs. Pectinal teeth number 19���22 in males and 18���20 in females. Movable finger of pedipalps with 7���8 rows of denticles, 7���8 ID and 5���8 OD. Dorsal carinae on pedipalp patella present and smooth. Metasoma V dorsal surface mesially smooth or with only several granules present. Metasoma I���II with 10 carinae, metasoma III with 8 carinae, metasoma IV���V with 2���4 carinae. Ventral carinae of metasoma I���III consist of a row of large granules. Metasoma IV���V ventrally and laterally with punctation developed, spaces among punctae smooth; metasoma II���III ventrally and laterally granulated and bumpy with punctation reduced. Entire tergites roughly granulate at least in male. Sternite VII densely granulated, with granulate carinae developed. Pedipalp, metasoma and telson very sparsely hirsute, rather glabrous. Tarsomere I of legs with 4���6 bristles longer in female. Ratio length/width of metasoma V 1.30���1.32 in both sexes. Pedipalp femur length/width ratio 3.3���3.7 in both sexes. DESCRIPTION. Total length of adults 29���44 mm in both sexes. Measurements of the carapace, telson, segments of the metasoma and segments of the pedipalps are given in Table 3. For habitus see Figs. 179���182. Coloration (Figs. 179���182). Carapace, tergites, metasoma and femur of pedipalp and legs usually black. Patella of pedipalps and legs brown to black. Pedipalp chela reddish brown, with yellowish brown fingertips. Tarsomeres of legs yellow to yellowish brown. Sternite VII is black, other sternites reddish brown to black with yellow median area in posterior margin of sternites IV���VI. Telson reddish brown to black. Mesosoma and carapace (Figs. 189���192, 199���200). Mesosoma with a median carina and is roughly granulated. Carapace is without carinae, roughly granulated except smooth interocular triangle. Sternites granulated except the median area in posterior margin. Pectinal teeth number 19���22 in males and 18���20 in females. Metasoma and telson (Figs. 183���188, 201, 227). Metasoma I���II with 10 granulated carinae. Metasoma III���V lacks lateral carinae, ventromedian and ventrolateral carinae are present on metasoma I���III, dorsolateral carinae are present on metasoma I���III and strongly reduced to absent on metasoma IV���V. Ventral carinae of metasoma I���III consist of a row of large granules. Metasoma I is granulate laterally, metasoma II���V laterally smooth; granulation absent on dorsal surfaces of all metasomal segments. Punctation on metasoma IV���V is ventrally and laterally developed, spaces among punctae are smooth. The entire metasoma and telson are glabrous, short, thin setae might issue from some punctae. Telson is shallowly punctate and lacks granules. Pedipalps (Figs. 202���221). 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 has seven smooth carinae, and the chela has 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, 7���8 ID and 5���8 OD. Legs (Figs. 193���198). Moderate tibial spurs present on third and fourth legs. Femur with four partly granulated carinae; patella with five rather smooth carinae; tibia is 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 4���6 bristles which are longer in female, fourth legs usually lack bristles. Tarsomeres I���II of all legs with two rather irregular rows of bristles. Measurements. See Table 3. AFFINITIES. The described features distinguish O. vignolii sp. n. from all other species of the genus. They are recounted in the key below. O. vignolii sp. n. was confused with O. zagrosensis Kovař��k, 2004, two here cited specimens of O. vignolii sp. n. from Yazd Province are part of type series of O. zagrosensis. However, these two morphologically very similar species differ by granulation of sternite VII (see key below).
