KEY WORDS: Scorpiones, Euscorpiops, Euscorpiidae, first description, Xizang (Tibet). KEY WORDS: Скорпион, Euscorpiops, Euscorpiidae, первоописание, Тибет. ABSTRACT. Euscorpiops karschi Qi, Zhu & Lourenзo, 2005 from China Xizang is reported on the basis of both sexes in the present paper. Its male is described and figured for the first time. РЕЗЮМЕ. Впервые найден самец Euscorpiops karschi Qi, Zhu & Lourenзo, 2005, ранее известный только по самкам из Тибета. Приведено иллюстрированное описание самца и самки. et al. [2007] described 1 new species of Euscorpiops from China. So far, 7 species of Euscorpiops have been recorded from China: E. novaki Kovaйнk, 2005 (Xizang): E. karschi Qi, Zhu & Lourenзo, 2005 (Xizang); E. asthenurus (Pocock, 1900) ( Xizang), E. kamengensis Bastawade, 2006 (Xizang); E. vachoni Qi, Zhu & Lourenзo, 2005 (Yunnan); E. shidian Qi, Zhu & Lourenзo, 2005 (Yunnan) and E. yangi Zhu, Zhang & Lourenзo, 2007 (Yunnan).

Introduction
Kovaйнk [2000] revised the family Scorpiopidae and recognized five genera: Alloscorpiops, Dasyscorpiops, Neoscorpiops, Parascorpiops, and Scorpiops. Kovaйнk [2000] separated Scorpiops into three groups: S. leptochirus species group, S. hardwickii species group, and S. petersii species group. He synonymized Euscorpiops with Scorpiops, suggesting that the former, as defined by Vachon [1980], should be considered invalid as there was a difference of only one external trichobothrium on the patella. Soleglad & Sissom [2001] placed the family Scorpiopidae and the chactid genus Chactopsis into the Euscorpiidae, and demonstrated the relationships of the euscorpiid subfamilies as (Euscorpiinae, (Megacorminae, Scorpiopinae)). They restored the genus Euscorpiops based of the position of chela trichobothrium Eb3, and the presence of an annular ring on the telson. Kovaйнk [2005] accepted this division, and considered Euscorpiops as a valid genus. The genus Euscorpiops is a small group comprising 16 species with a narrow distribution in South and Southeast Asia including India, Bhutan, Pakistan, Bengal, Malaysia, Thailand, Vietnam, Laos and China [Tikader & Bastawade, 1983; Kovaйнk, 2004, 2005; Qi et al., 2005, 2007]. Recently, Qi et al. [2005] described four new species of Euscorpiops, and proposed a key for the known Chinese species of Scorpiopinae. Zhu

Methods
Illustrations and measurements were produced using a TTL-II stereomicroscope with an Abbe drawing device and an ocular micrometer. Measurements follow Sissom et al. [1990] and are given in mm. Trichobothrial notations follow Vachon [1974] and morphological terminology mostly follows Hjelle [1990]. Terminology of metasomal carination follow Vachon [1952] and terminology of pedipalp chelal carinae follow Prendini [2000]. Type series of the new species is deposited in the Museum of the College of Life Sciences, Hebei University (MHBU). All measurements are given in mm.

DIAGNOSIS. Euscorpiops karschi moderate sized and also differing from the other members of the group in possessing evenly scattered coarse granules of moderate size on carapace. Body color basically brown; the aculeus is shorter than half of vesicle length; all tergites with coarse and evenly scattered moderate granules; pectinal tooth count 7 to 9; dorsal carinae of metasoma IV end in an almost lobe-shaped denticle. Euscorpiops karschi can be distinguished from other Eucorpiops species from China easily, in particular from E. shidian Qi, Zhu & Lourenзo, 2005, the most similar species of the genus by the following features: (1) Ventral surface of patella bears 8 trichobothria, E. shidian with 11; (2) pedipalp fingers in both sexes are curved markedly, nearly straight in E. shidian;. (2) evenly scattered coarse granules of moderate size on carapace, differing size and smooth granules in E. shidian.
