ETYMOLOGY. Named after the Sistan region of the Iranian province of occurence.

DIAGNOSIS. Total length of adults 75–95 mm. Trichobothrium db on fixed finger of pedipalp situated between trichobothria et and est or est and esb. Male with slightly narrower metasomal segments, width of pedipalp chela same in both sexes. Pectinal teeth number 26– 30 in males, 23–28 in females. Nearly entire body hirsute, pedipalps, dorsal surface of mesosoma, legs, lateral and ventral surfaces of metasomal segments, and vesicle hirsute rather densely. Hairs on patella of pedipalps are long. Chelicerae brown to black, reticulate. Color yellow to yellowish green or brown, except black central part of carapace and tergites I–VI, telson, posterior part of fourth and whole fifth metasomal segment. Femur of pedipalp with 4 carinae. Patella with 8 carinae. Chela lacks carinae. Movable fingers of pedipalps with 15–16 rows of granules and 5 or 6 terminal granules. Seventh sternite with 4 well marked carinae. First metasomal segment with 10 carinae; second with 8 or 10 carinae; third and fourth with 8 carinae; fifth with 5 carinae, 3 ventral (one median, two lateral) and two dorsal. All metasomal segments generally smooth, without granules between carinae. All metasomal segments of both sexes longer than wide. Metasomal segment II length/width ratio more than 1.6.

DESCRIPTION. The total length is 75–95 mm, males usually smaller than females. Chelal trichobothrium db usually located between est and et, or may be on level with trichobothrium est, rarely between est and esb. Male has the fingers proximally almost straight and female absolutely steaight, there is not sexual dimorphism in shape of chela of pedipalp. Chelicerae are brown to black, with reticulation, the tips of teeth on cheliceral fingers are black. For the position and distribution of trichobothria see Figs. 36–39 and 41–42.

COLORATION ( Figs. 57–64 , 69–76 ). The central parts of carapace and tergites I–VI, telson, posterior part of fourth and whole fifth metasomal segment, and pedipalp chela are reddish black to black; the metasoma I– III, femur and patella of pedipalps, margins of tergites I– VI, tergite VII, sternites, and legs are yellow to yellowish green or brown. The tarsomeres of legs are yellow.

MESOSOMA AND CARAPACE ( Figs. 61–64 ). The carapace is carinate and unevenly covered by granules of varying size; much of the granulation is fine, but some granules are larger and distinctly rounded. Tergites I–VI bear three carinae and are granulated, with some intercarinal granules small and others larger and rounded. Tergite VII is pentacarinate. The pectinal tooth count is 26–30 (28.928 /18/) in males and 23–28 (24.55 /24/) in females. The pectinal marginal tips extend to third of the fourth sternite in female and half of the fourth sternite in male. The pectines have three marginal lamellae and seven to nine middle lamellae. The lamellae bear numerous dark long setae, each fulcrum with two to three setae. All sternites are smooth and sparsely hirsute. The seventh sternite bears four granulate carinae. The other sternites bear two furrows.

PEDIPALPS ( Figs. 33–45 ). The pedipalps are hirsute and almost smooth. The femur bears four granulated carinae. The patella bears eight carinae, ventral and external are smooth, without granules and obsolete; dorsal and internal are granulate. The chela is without carinae. The movable fingers of pedipalps bear 15–16 rows of granules and five or six terminal granules.

LEGS ( Figs. 65–68 ). The tarsomeres bear two rows of short and strong spiniform setae on the ventral surface and numerous macrosetae on the other surfaces. Pedal spur of legs without setae. Femur and patella with carinae indicated. Tibial spurs present and long on third and fourth legs and absent in the other legs.

METASOMA AND TELSON ( Figs. 69–76 ). All metasomal segments are hirsute rather densely. All metasomal segments of both sexes longer than wide. The segment I bears 10 carinae; segment II bears 10 or 8 carinae; segments III and IV bear 8 carinae; and segment V bear five carinae, three ventral and two dorsal. All carinae are with consistent denticles. The telson is only sparsely hirsute, bulbous, bumpy and finely granulated, more in females.
