description: <i>Mesobuthus caucasicus intermedius</i> (Birula, 1897) Figs 2, 11–13 <i>Buthus caucasicus</i> forma γ <i>intermedia</i> Birula, 1897: 387. <i>Mesobuthus caucasicus intermedius</i>: Vachon, 1958: 150, Fig. 31. <i>Olivierus caucasicus intermedius</i>: Farzanpay, 1987: 156. <b>Material examined.</b> Type material not examined. Kazakhstan: Almaty Area, Kurty District, Taukum Desert, 25.5 km SE of Topar, 44°53.002'N, 75°17.138'E, 373 m alt., 9/V/2003, L. Prendini &amp; A. V. Gromov leg., 4 females and 3 males (AMNH); South Kazakhstan Area, Chardara District, 3 km W of Chardara, 41°16.106'N, 67°53.228'E, 287 m alt., 20/VI/2003, L. Prendini &amp; A. V. Gromov leg., 1 female and 3 males (AMNH). <b>Diagnosis.</b> <i>Coloration</i>. Basically brownish-yellow; all carinae and posterior edges of carapace and tergites with blackish-brown to black pigments; dorsal surfaces of segments I–IV on metasoma and each surface of segment V with irregular netlike dark pigments. Pedipalps: brownish-yellow; femur and patella with dark pigments, especially around carinae; manus with irregular netlike dark pigments; rows of granules on dentate margins of the fingers blackish-brown. Legs: pale yellow to yellow; tip of femur and base of patella with some dark spots. <i>Morphology</i>. Total length 66–77 mm in females and 55–60 mm in males. Prosoma: anterior margin with a weak median concavity, not serrate; all carinae moderately strong, granular, and granules moderately developed; Mesosoma: Tergite: I to VI tricarinate; carinae on I weak, and carinae on II–VI moderately to strong, granular; the intercarinal surfaces relatively smooth, except for the segments I–III with sparse and fine granules; exterior surfaces coarsely granular. Pectinal teeth number 20–25 in females and 26–30 in males. Metasoma: Segments I–V with 10-8-8-8-5 complete carinae; median lateral carinae complete on segment I, only with sparse granules and covered 1/3 length of segment on II, and obsolete, remaining 1–3 granules at distal end on III; ventrolateral carinae on segment V strong, serrate, becoming stronger gradually from anterior to posterior; lateral surfaces smooth, dorsal with some fine granules and ventral with sparse large granules. Aculeus longer than a half of telson length. Pedipalps: Trichobothrial pattern: Orthobothriotaxic A-β (Vachon, 1974, 1975). Dentate margins of movable and fixed fingers with 12 and 11 oblique rows of granules respectively; outer accessory denticles becoming smaller from base to tip markedly, and obviously smaller than inner accessory denticles on the tip. Legs: Tarsus ventrally with two moderate to long longitudinal rows of setae. <b>Distribution.</b> China (Xinjiang Uygur Autonomous Region), Iran (northwest), Kazakstan, Kirghizstan, Tajikistan, Turkmenistan, Uzbekistan (Fet and Lowe, 2000). <b>Note.</b> Although our field works in Xinjiang are going along in past four years, and we got a large amount of specimens, we could not find any evidence to support the distribution of <i>Mesobuthus caucasicus intermedius</i> in China. But here, we decide to refer to Fet and Lowe (2000) before our completing the investigations.
