ETYMOLOGY. The new species name honors our colleague Dr. RahŞen S. Kaya (Bursa, Turkey), for her great contributions to the field of arachnology.

DNA DATA. Mesobuthus rahsenae sp. n. is represented in our survey by one DNA sequence from Turkey (Erzincan Province) ( Table 16).

DIAGNOSIS. Total length of adults 38 mm (male) to 62 mm (female). Trichobothrium db on fixed finger of pedipalp situated between trichobothria est and esb, near to est. Male with fingers proximally more twisted than in female. Pedipalp chela length/width ratio 3.5–3.7 in both sexes. Pectinal teeth number 22–28 in male, 18–22 in female. Chelicerae yellow, without reticulation. Pedipalps and metasoma sparsely hirsute. Carapace and tergites yellow, usually black pigmented; metasoma, telson, pedipalps and legs yellow with dark spots. Femur of pedipalp with 4–5 granulated carinae. Patella with 8 usually smooth carinae, both internal and dorsal can be granulated. Chela lacks carinae. Movable fingers of pedipalps with 11–12 cutting rows of denticles and 5–6 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 smooth, finely granulated on margins 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 1.2–1.45, metasoma IV 1.5–1.8 in both sexes. Telotarsus III ventral setation represented by short and strong spiniform setae. Tarsi hirsute, in adults with 7–9 retroinferior macrosetae on basitarsus III. Telson rather bulbous in female. Telson length to depth ratio is 2.4–2.5 in female. Anal lobe divided into three parts.

DESCRIPTION. Total length of adult males 38–45 mm, 42– 62 females. Trichobothrium db on fixed finger of pedipalp situated between trichobothria est and esb, near to est. Male has the fingers proximally more twisted than in female. For measurements, see Table 10.

Coloration ( Figs. 843–846 View Figures 843–846 ). Carapace and tergites are yellow with dark pigmentation usually reduced. Telson, metasoma, pedipalps and legs are yellow usually with dark spots, 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. 875–878 View Figures 875–882 ). 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 22–28 in males, 18–22 in females. Pectinal marginal tips extend to about quarter of the fifth sternite in males and end of sternite IV in females. Pectines have three marginal lamellae and seven to eight middle lamellae. Lamellae with numerous long setae, each fulcrum with three to five dark setae. Sternites are smooth and sparsely hirsute. The sternite VII smooth, finely granulated on margins with four well marked smooth or granulated carinae. Other sternites have two furrows.

Pedipalps ( Figs. 855–874 View Figures 855–874 ). 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 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. 879–882 View Figures 875–882 ). Telotarsus III ventral setation represented by short and strong spiniform setae. Tarsi hirsute, in adults with 7–9 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. 847–854 View Figures 847–854 ). All metasomal segments are 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 smooth. Ventrolateral carinae of metasoma V posteriorly with several lobate denticles. Telson is sparsely hirsute, rather bulbous and smooth. Anal lobe divided into three or four parts.
