TYPE MATERIAL. Pakistan, Khyber Pakhtunkhwa Province (formerly North-West Frontier Province), Swat District, Matta (34.84°N 72.21°E), 25 October 2006, 1♂ 1♀ (paratypes) , 28 July 2007, 1♂ (holotype) 3♂ juvs. 4♀ juvs. (paratypes), leg. Zubair Ahmed; FKCP.

ETYMOLOGY. This species is named after my good friend and colleague, a prominent scorpiologist Ersen Aydın Yağmur ( Turkey).

DIAGNOSIS (♂ ♀). Total length 43–47 mm. Base color uniformly orange to brown, legs yellow. Pectinal teeth number 8–9 in males, 7–8 in females; fulcra absent; three marginal and five middle lamellae present. Patella of pedipalp with 17 (5 eb, 2 esb, 2 em, 4 est, 4 et) external and 18 ventral trichobothria. Chela of pedipalp with 4 ventral trichobothria located on ventral surface. Chelal trichobothrium Eb 3 is located in the proximal half of external surface between trichobothria Dt and Db. Fingers of pedipalps flexed in both sexes. Chela length to width ratio 3.57 in males, 3.40 in females. Pedipalp movable finger with ca 70 IAD, which have the same size as MD (more than 100 in number) and form a second row; there are also 5 ID and 13–15 OD present. Tarsomere II of leg III with seven stout median ventral spines in a row and two other parallel spines. Metasoma I with 10, and metasoma II–IV with 8 carinae. Telson elongate and granulate, length to depth ratio 3.43 in males and 3.00 in females; annular ring indicated.

DESCRIPTION (♂ ♀). Total length 43–47mm. The habitus is shown in Figs. 186–187 . For position and distribution of trichobothria of pedipalps see Figs. 188–194 . Sexual dimorphism: adult males have relatively larger pectens; fingers of pedipalps are flexed in both sexes.

Coloration ( Figs. 186–187 ). The base color is uniformly orange to brown, legs yellow, telson orange. Chelicerae are yellow and slightly reticulate, fingers reddish black.

Carapace and mesosoma ( Figs. 197–198 ). The entire carapace is covered with large granules; carinae are absent. The anterior margin of the carapace is markedly depressed, convex in the middle. The carapace bears three lateral eyes, of which two are normal and one is reduced. The mesosoma is granulated, with one median carina. Tergite VII is pentacarinate. The sternites are smooth with two parallel furrows except sternite VII, which is finely granulated with two carinae indicated. Pectinal teeth number 8–9 in males, 7–8 in females. The pectens have 3 marginal lamellae and 5 middle lamellae; fulcra are absent.

Metasoma and telson ( Figs. 201–204 ). The metasoma is sparsely hirsute and granulated, with sparse granules. Metasomal segment I with 10, II–IV with 8, and V with 5 carinae. The median lateral carinae of metasoma V are indicated by isolated granules that may coalesce into carinae. The dorsolateral carinae of segments II–IV posteriorly terminated in a pronounced tooth. The telson is elongate and smooth, with annular ring indicated.

Pedipalps ( Figs. 188–196 ). The pedipalps are very sparsely hirsute. The patella of pedipalp with 17 (5 eb, 2 esb, 2 em, 4 est, 4 et) external and 18 ventral trichobothria. The chela bears 4 ventral trichobothria located on the ventral surface. The femur and patella are finely granulated. The femur has 5 granulose carinae, and the patella has 5 carinae with pronounced dorsal and ventral patellar spurs. The manus dorsally bears fine, rounded granules, which in the central area do not form another carina. The external surface of the chela is densely covered by minute granules and bears an almost complete median carina. The movable fingers bear ca 70 IAD, which have the same size as MD (more than 100 in number) and form a second row. There are also 5 ID and 13–15 OD present.

Legs ( Figs. 199–200 ). The tibia and tarsomeres of legs with several setae not arranged into bristlecombs on dorsal surfaces but with rows of spines on dorsolateral surfaces and on legs I – II and partly III also on ventrolateral surface. Tarsomere of legs I–IV with 5–7 stout median ventral spines in a row and two other parallel spines. The femur bears 3–4 incomplete and patella, 4–5 developed carinae.

Measurements. See Table 3.

AFFINITIES. The described features distinguish S. yagmuri sp. n. from all other species of the genus. Among species, which have chelal trichobothrium Eb 3 placed in proximal half of external surface between trichobothria Dt and Db, only one other species, S. pseudomontanus Kovařík & Ahmed, 2009 , has 18 ventral trichobothria on the pedipalp patella. It is possible to differentiate these two species according to the shape of chela because chela length/width ratio in female is 3.4 in S. yagmuri sp. n. and 2.9 in S. pseudomontanus ; the movable fingers bear ca 70 IAD in S. yagmuri sp. n. and ca 45 in S. pseudomontanus .
