DNA DATA. This new species, in our opinion, was represented among the populations studied by Mirshamsi et al. (2010) in their survey of Iranian Mesobuthus (one DNA sequence from Sistan & Baluchistan Province, 90 km S of Zahedan, 28.74°N 60.77°E; Table 16) .

ETYMOLOGY. The new species is named in honor of our colleague Shakhrokh Navidpour, whose research group collected most impressive materials of scorpions from Iran over the years.

DIAGNOSIS. Total length of adults 38 mm (male) to 55 mm (female). Trichobothrium db on fixed finger of pedipalp situated between trichobothria est and esb, near to est. Male with fingers proximally slightly more twisted than in female. Pedipalp chela length/width ratio 4.17–4.57 in both sexes. Pectinal teeth number 20–26 in male, 15–22 in female. Chelicerae yellow, without reticulation. Pedipalps and metasoma sparsely hirsute. Carapace and tergites yellowish to reddish brown, black pigmented; metasoma, telson, pedipalps and legs yellowish brown, only part of metasomal segment V black. Femur of pedipalp with 4–5 granulated carinae. Patella with 8 usually smooth carinae, only dorsal carinae can be granulated. Chela lacks carinae. Movable fingers of pedipalps with 11–12 cutting rows of denticles and 5 terminal denticles. Central lateral and posterior lateral carinae of carapace joined to form a continuous linear series of granules to posterior margin. Sternite VII smooth to finely granulated with 4 well marked smooth or granulated carinae. Metasomal segment I with 10 carinae; segments II to IV with 8 carinae, other two carinae are indicated by incomplete row of denticles on metasomal segments II and III; segment V with 5 carinae. Metasoma with all carinae granulated. Intercarinal surfaces on metasoma laterally smooth. Length to depth ratio of metasoma III 1.7–1.9, metasoma IV 1.9–2.2 in both sexes. Telotarsus III ventral setation represented by short and strong spiniform setae. Tarsi hirsute, in adults with 10–15 retroinferior macrosetae on basitarsus III. Telson elongated in both sexes. Telson elongate, telson length to depth ratio is 2.85–3.05 (female) to 3.00–3.15 (male). Anal lobe divided into three or four parts.

DESCRIPTION. Total length of adult males 38–45 mm, 42– 55 females. Trichobothrium db on fixed finger of pedipalp situated between trichobothria est and esb, near to est. Male has the fingers proximally a slightly more twisted than in female. For measurements, see Table 8.

Coloration ( Figs. 691–694 ). Carapace and tergites are yellowish to reddish brown with dark pigmentation. Telson, metasoma, pedipalps and legs are yellow without dark spots, only metasomal ventral carinae and part of metasomal segment V are black. Chelicerae yellow, without reticulation, the tips of denticles on cheliceral fingers are black.

Mesosoma and carapace ( Figs. 723–726 ). Carapace carinate, unevenly covered by granules of varying size; much of the granulation is fine but some granules are larger and distinctly rounded. Central lateral and posterior lateral carinae of carapace joined to form a continuous linear series of granules to posterior margin. Tergites I–VI with three carinae and are granulated, with some intercarinal granules small and others larger and rounded. Tergite VII is pentacarinate. Pectinal tooth count is 20–26 in males, 15–22 in females. Pectinal marginal tips extend to about half of sternite IV in males and onefourth of sternite IV in females. Pectines have three marginal lamellae and eight to nine middle lamellae. Lamellae with numerous long setae, each fulcrum with three to five dark setae. Sternites are smooth and sparsely hirsute. Sternite VII smooth to finely granulated, with four well marked smooth or granulated carinae. Other sternites have two furrows.

Pedipalps ( Figs. 703–722 ). Pedipalps hirsute and smooth, only femur is sparsely finely granulated. Femur has four to five granulated carinae, the middle carina on internal surface consists of strong irregular granules. Patella with eight carinae, of which internal and dorsal can be granulated. Chela without carinae. Movable fingers of pedipalps have 11–12 cutting rows of denticles, each with external and internal denticles present, and five terminal denticles.

Legs ( Figs. 727–730 ). Telotarsus III ventral setation represented by short and strong spiniform setae. Tarsi hirsute, in adults with 10–15 retroinferior macrosetae on basitarsus III. Femur with only several macrosetae. Femur and patella with carinae well developed. Tibial spurs present and moderate on legs III and IV and absent on the other legs.

Metasoma and telson ( Figs. 695–702 ). All metasomal segments only sparsely hirsute. Metasomal segment I with 10 carinae, II–III with 8 carinae but other two lateromedian carinae are indicated by incomplete row of granules, IV with 8 carinae, and V with 5 carinae. Metasoma with all carinae granulated. Intercarinal surfaces on metasoma laterally smooth. Ventrolateral carinae of metasoma V posteriorly with several lobate denticles. Telson is only sparsely hirsute, elongate and smooth. Anal lobe divided into three or four parts.

DISTRIBUTION. Iran (Kerman and Sistan & Baluchistan Provinces) (Figs. 1155, 1157).
