Pedipalp femur and trochanter, dorsal (38), internal (39), and ventral (40) views. The trichobothrial pattern is indicated in Figures 33–36, 38–39 (white circles). Coloration ( Figs. 1–4 ). Carapace, tergites, metasoma and usually femur of pedipalps and legs black, tibia and tarsomeres of legs and fingers of pedipalps yellow. Patella of legs and pedipalps and pedipalp chela yellowish brown to brown. Sternite VII black, other sternites reddish brown to black with yellow median area present in posterior margin of sternites IV–VI. Telson reddish brown. Mesosoma and carapace ( Figs. 11–14 , 20–21 ). Mesosoma with a median carina, densely granulated. Carapace roughly granulated with smooth areas, mainly around medial eyes. Carination of carapace reduced to absent. The seventh sternite granulated, with four wide granulated carinae, the other sternites are granulated except smooth median area. Pectinal teeth number 20–22 in both sexes. Metasoma and telson (Figs. 5–10, 22, 222). Metasoma I– II with 10 granulated carinae. Metasoma II–V lack lateral carinae, ventromedian carinae present on metasoma I–III, ventrolateral carinae present on all metasomal segments, dorsolateral carinae present on metasoma I–III and reduced to absent on metasoma IV–V. Ventral carinae of metasoma I– III consist of small granules irregularly forming two or three rows. All metasomal segments are granulated laterally, more in metasoma I–III; granulation absent on dorsal surfaces of all metasomal segments and ventral surfaces of segments IV–V. Segments IV–V ventrally and laterally are shallowly punctate; 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. 23–40 ). The distance between trichobothria d 1 and d 3 on the femur of pedipalp approximately equals that between d 3 and d 4 ; trichobothrium e 1 is situated in level with d 4 . Trichobothrium d 2 on the dorsal surface of pedipalp femur absent or reduced. Femur of pedipalp with five granulated carinae. Patella with seven smooth reduced carinae; chela with smooth carinae, which might be discernible throughout the length of the fixed finger. The entire pedipalp only very sparsely hirsute. Movable fingers with 8 rows of denticles, 8–9 ID and 7–8 OD. Legs ( Figs. 15–19 ). Moderate 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, short in male and long in female; fourth legs lack bristlecombs. Tarsomeres I–II of all legs with two rather irregular rows of bristles. Measurements . See Table 1 . AFFINITIES. The described features distinguish O. hormozganensis sp . n . from all other species of the genus. They are recounted in the key below. O. hormozganensis sp . n . is similar to O. varius Kovařík, 2004 . These two species can be distinguished according to the metasoma morphology. In the key below, we used the difference in granulation of carinae. Another difference is in the granulation of the ventral surfaces on metasoma I–III, which are densely granulated in the male of O. hormozganensis sp . n . (Fig. 10) and rather smooth with several granules in O. varius . DISTRIBUTION. Iran , Hormozgan Province ( Fig. 228 ).
