ETYMOLOGY. The new species is named in honor of our colleague Omid Mirshamsi who conducts the Iranian scorpion taxonomy research for many years, including important work published on Mesobuthus .

DIAGNOSIS. Total length of adults 35 mm (male) to 55 mm (female). Trichobothrium db on fixed finger of pedipalp situated between trichobothria est and esb, near to est or with level with est. Male with fingers proximally more twisted than in female. Pedipalp chela length/width ratio 3.4–3.6 in both sexes. Pectinal teeth number 21–27 in male, 18–22 in female. Chelicerae yellow, without reticulation. Pedipalps densely hirsute and metasoma hirsute with long setae. Carapace and tergites yellow with reduced pigmentation; metasoma, telson, pedipalps and legs yellow, only part of metasomal segment V can be black. Femur of pedipalp with 4–5 granulated carinae. Patella with 8 usually smooth carinae, both dorsal carinae are 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 not joined to form a continuous linear series of granules to posterior margin. Sternite VII finely granulated on margins with 4 well marked 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 I laterally finely granulated. Length to depth ratio of metasoma III 1.3–1.45, metasoma IV 1.6–1.8 in both sexes. Telotarsus III ventral setation represented by short and strong spiniform setae. Tarsi hirsute, in adults with 5–9 retroinferior macrosetae on basitarsus III. Telson bulbous, mainly in female. Anal lobe divided into three or four parts.

DESCRIPTION. Total length of adult males 35–40 mm, 38– 55 females. Trichobothrium db on fixed finger of pedipalp situated between trichobothria est and esb, near to est or in level with est. Male has the fingers proximally more twisted than in female. For measurements, see Table 8.

Coloration ( Figs. 650–653 ). Carapace and tergites are yellow with reduced pigmentation. Telson is yellow. Metasoma, pedipalps and legs are yellow without dark spots, only part of metasomal segment V can be black. Chelicerae yellow, without reticulation, the tips of denticles on cheliceral fingers are black.

Mesosoma and carapace ( Figs. 683–686 ). Carapace carinate, unevenly covered by granules of varying size; much of the granulation is fine but some granules are larger and distinctly rounded. 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 21–27 in males, 18–22 in females. Pectinal marginal tips extend to about half of the fifth sternite in males and half of sternite IV in females. Pectines have three marginal lamellae and seven to nine middle lamellae. Lamellae with numerous long setae, each fulcrum with three to five dark setae. Sternites are smooth and sparsely hirsute. The sternite VII finely granulated on margins with four well marked granulated carinae. Other sternites have two furrows.

Pedipalps ( Figs. 662–682 ). Pedipalps densely hirsute. 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 are granulated. The chela is with smooth carinae only indicated. Movable fingers of pedipalps have 11–12 cutting rows of denticles, each with external and internal denticles present, and five terminal denticles.

Legs ( Figs. 687–690 ). Telotarsus III ventral setation represented by short and strong spiniform setae. Tarsi hirsute, in adults with 5–9 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. 654–661 ). 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 finely granulated. Ventrolateral carinae of metasoma V posteriorly with several large lobate denticles. Telson is only sparsely hirsute, bulbous and smooth. Anal lobe divided into three or four parts.

COMMENTS. No DNA data on M. mirshamsii sp. n. are yet available. This new species, in our opinion, was not represented among the populations studied by Mirshamsi et al. (2010) in their DNA survey of Iranian Mesobuthus .

DISTRIBUTION. Iran (Hormozgan Province) (Figs. 1155, 1157).
