description: <i>Mesobuthus longichelus</i> sp. n. urn:lsid:zoobank.org:act: 701C6466-5B03-46D5-ADD2-42A4EFDACA21 Figs 1, 4–10, 17–21 <b>Type material.</b> Holotype female (MHBU), China: Xinjiang, northern piedmont of the Tianshan Mountains, 10km S of Jinghe County, 44°31'N, 82°54'E, 7 Aug. 2008, M. S. Zhu, F. Zhang, G. X. Han and D. Sun leg.; 1 juvenile female (MHBU) and 1 juvenile male (MHBU) paratypes, all the same as for holotype. <b>Diagnosis.</b> Species of moderate size, with respect to the genus. General coloration yellow to pale brownish-yellow; ventral and lateral surfaces of metasoma segment V with inconspicuous variegated black pigment. Chela smooth without carinae, long and slender. The metasoma segments elongate; median lateral carinae complete on segment I, only with sparse granules and covered 1/2–2/3 length of segment on II and obsolete, remaining 1–2 granules at distal end on III; ventrolateral carinae of segment V strong, serrate, becoming strongly marked posteriorly and with 2–3 markedly large and extroversive lobed granules; aculeus markedly longer than a half of telson length. <b>Figure Ι.</b> <i>Mesobuthus longichelus</i> sp. n. Female holotype. Dorsal view. Scale bar = 5.0 mm. Dentate margins of movable and fixed fingers with 12 and 11 oblique rows of granules. Pectinal tooth count 22–23 in females and 27–28 in male. <i>Mesobuthus longichelus</i> sp. n. is undoubtedly associated with <i>Mesobuthus caucasicus intermedius</i> and <i>Mesobuthus caucasicus przewalskii</i>, but it can be distinguished by above features, and especially by these three characters: the shape of chela, the median lateral carinae of segment II and III on metasoma, and the shape of ventrolateral carinae of segment V on metasoma. <b>Figures 2–Ι0. 2</b> <i>Mesobuthus caucasicus intermedius</i> (Birula, 1897). Female <b>3</b> <i>Mesobuthus caucasicus przewalskii</i> (Birula, 1897). Female <b>4–Ι0</b> <i>Mesobuthus longichelus</i> sp. n. Female holotype. <b>2–4</b> Carapace, dorsal aspect <b>5</b> Genital operculum and pectines, ventral aspect <b>6–7</b> Patella (6. dorsal, 7. external) <b>8</b> Femur, dorsal aspect <b>9–Ι0</b> Chelicera (9. ventral, 10 dorsal). Scale bar = 1.0mm. <b>Etymology.</b> The specific name derives from the Latin “ <i>longi</i> + <i>chel</i> ”, meaning long and chela, referring to the long and slender chela, especially the manus. <b>Description.</b> Based on female holotype. <i>Coloration</i>. Basically brownish-yellow. Prosoma: carapace brownish-yellow, with only blackish anterior median carinae, other carinae without pigment; eyes surrounded by black pigment. Mesosoma: brownish-yellow; segments I to VI with a distinct black-
