ETYMOLOGY. Named after Mitra Tavighi, a student of medical entomology in Kerman (Sirjan University).

DIAGNOSIS. Total length of adults 49.8–52.5 mm. Dorsal trichobothria of femur arranged in beta -configuration, orthobothriotaxic. Cheliceral fixed finger with two ventral denticles. Third and fourth legs with tibial spurs. Tergites I–II bear five carinae and tergites III–VI bear three carinae. Pectines with fulcra. Pectinal teeth number 31–32 in males and 21–22 in females. Color generally yellow, with only a few dark zones on carapace, tergites and sternites. Chelicerae yellowish brown, without reticulation. Pedipalps and metasoma sparsely hirsute. Movable finger of pedipalp with 11–12 rows of granules and with 7–8 terminal granules of which 4–5 form an apical row. Ventral carinae of second and third metasomal segments with two pairs of strong teeth. Anal arch with three strong, long and conical lateral lobes. All metasomal segments longer than wide. Telson bulbous, with aculeus shorter than vesicle.

DESCRIPTION. The total length of adults is 49.8–52.5 mm. Sexual dimorphism is not readily apparent; the width of pedipalp chela is the same in both sexes, and there is no difference between males and females in the length of pedipalps and metasomal segments; differences are only in pectines and the genital operculum. Chelicerae are yellowish, without reticulation, the tips of teeth on cheliceral fingers are black. For the position and distribution of trichobothria see Figs. 17–20.

COLORATION. Generally yellow with only a few dark zones on the carapace, tergites and sternites. Tergites and sternites have greenish to gray spots in the anterior parts, but posterior and lateral margins are yellow. Only the seventh tergite can by entirely dark. The metasoma, telson, pedipalps and legs are yellow. Only the fifth metasomal segment may be darker.

MESOSOMA AND CARAPACE. The carapace is carinate and bears several solitary granules ( Fig. 15). Tergites I– II bear five carinae, tergites III–VI bear three carinae, and are granulated. Tergite VII is pentacarinate. The pectinal tooth count is 31–32 in males and 21–22 in females. The pectinal marginal tips extend nearly to onequarter of the sixth sternite in males and one-half of the fourth sternite in females. The pectines have three marginal lamellae and six (female) to eight (male) middle lamellae. The lamellae bear numerous long, dark setae, each fulcrum with three to five setae. All sternites are finely granulated (male) or smooth (female) and sparsely hirsute. The fourth to seventh sternites bear four granulated (male) or obsolete (female) carinae. The third sternite bears two carinae.

PEDIPALPS. The pedipalps bear sparse long setae. The femur bears three to four granulated carinae and its dorsal surface is weakly granulated in males and without granules in females. The patella bears eight carinae, most of them granulated. The chela is without carinae and smooth. The movable and fixed fingers of pedipalps bear 11–12 rows of granules, and the movable finger also has 7–8 terminal granules of which 4–5 form an apical row.

LEGS. The tarsomeres bear two rows of macrosetae on the ventral surface and numerous macrosetae on the other surfaces, which on legs I–III form bristle combs. The femur and patella may bear four to six carinae, which may be granulate.

METASOMA AND TELSON. All metasomal segments are sparsely hirsute and longer than wide. Segments I–II bear 10 carinae, segment II bears 8 or 10 carinae, segment IV bears 8 carinae, and segment V bears 5 carinae. All metasomal segments are finely granulated (male) or smooth (female), with bigger granules confined to the ventral surface of the fifth segment. All carinae are granulated, without pigmenation. Anteroventral margins of the second to fourth metasomal segments each bear a transverse row of 6 to 8 enlarged granules. Ventral carinae of the second and third metasomal segments bear two pairs of strong teeth ( Fig. 23). The anal arch has three strong conical and three reduced lateral lobes, and two strong conical and three to four reduced ventral lobes. Ventrolateral carinae on the fifth metasomal segment bear three strong, lobate and conical granules.The telson is smooth and bulbous, with the aculeus shorter than the vesicle and sparsely hirsute.

AFFINITIES. The described features distinguish O. tavighiae sp. n. from all other species of the genus. They are recounted in the key below. The occurrence and morphology make the new species close to O. bidentatus Lourenço et Pézier, 2002 , which is bigger (60–70 mm) than O. tavighiae sp. n. (50–52.5 mm), has the movable finger of pedipalp with 13–14 rows of granules ( O. tavighiae sp. n. has 11–12 rows), and its lateral lobes on the fifth and third metasomal segments are differently shaped ( Fig. 23 versus Fig. 39).
