Until now, there are 26 scorpion species of 7 genera of 5 families recorded in Xizang (China). Xizang Autonomous Region (Tibet) is the scorpion biodiversity richest area in China (53 scorpion species of 12 genera of 5 families), also the highest altitude habitat of scorpions in the world. We present information of type specimens, an identification key of the scorpion species from Xizang, the distribution, updated feature pictures, and discussion on the disputed species. The redescriptions of Scorpiops jendeki Kovařík, 2000 (Yunnan) and Scorpiops tibetanus Hirst, 1911 (Xizang), comments and feature figures of species of genus Scorpiops are provided for identification.

Xizang (Tibet) Autonomous Region is located in southwest China (26°52'–36°32'N, 78°24'–99°06'E), about 1,228,400 km2 (≈12.5% of China), famous as the “Roof of the world”. Xizang facing Xinjiang and Qinghai to the north, Sichuan and Yunnan to the east, while India, Myanmar, Bhutan, Sikkim, Nepal and Kashmir to the south PageBreakand west (Bai, 2004). It is the main part of the Qinghai-Tibet Plateau, with an average elevation of more than 4,000 m, its central part above 4,500 m.PageBreak Hirst, 1911 (Euscorpiidae) was the first scorpion species established by Xizang (China) specimens. Hirst (1911) described this new species by comparing it with some relatives briefly. Almost ninety years later, Kovařík (2000a and b) reported 2 new species: Kovařík, 2000 (Chaerilidae); Kovařík, 2000 and 1 new record: (Gervais, 1843). Zhu, Qi and Song (2004) summarized the historical scorpion records in China: totally 19 species and subspecies of scorpion s belonging to 9 genera and 5 families according to the relevant literatures, and presented the distribution information on species from Xizang: (Thorell, 1876) (Scorpionidae) and Pocock, 1893. From 2005, much more work on Xizang was finished. Kovařík (2005) described Kovařík, 2005 (Euscorpiidae). After scientific expedition, Qi, Zhu and Lourenço (2005) published the first comprehensive report of scorpions from Xizang, discovered 6 new species belonging to Chaerilidae () and Euscorpiidae ( and ): Qi, Zhu & Lourenço, 2005; Qi, Zhu & Lourenço, 2005; Qi, Zhu & Lourenço, 2005; Qi, Zhu & Lourenço, 2005; Qi, Zhu & Lourenço, 2005; and Qi, Zhu & Lourenço, 2005. Lourenço, Qi and Zhu (2005) identified Lourenço, Qi & Zhu, 2005 (Buthidae), and Lourenço, Qi & Zhu, 2005. Lourenço and Qi (2006) established of a new genera by specimens from Xizang: Lourenço & Qi, 2006 (Hemiscorpiidae) and new species: Lourenço & Qi, 2006. Bastawade (2006) reported 2 new species and 4 new records: Bastawade, 2006; (Pocock, 1890); Pocock, 1899; (Pocock, 1900); Bastawade, 2006; Pocock, 1893 by the specimens from South Xizang (China). Lourenço and Zhu (2008) discovered a new species belonging to (Buthidae): Lourenço & Zhu, 2008, at the same time, was a new recorded genus to Xizang. Zhu, Han and Lourenço (2008) summarized the chaerilid scorpions of China, and provided the redescriptions for Qi, Zhu & Lourenço, 2005 and Kovařík, 2000; pointed out that (Pocock, 1890) which was described by Qi et al. (2005) was misidentified, and described one new species: Zhu, Han and Lourenço, 2008, all of them from Xizang. Di and Zhu (2009a and b) established 2 new species: Di & Zhu, 2009 and Di & Zhu, 2009 successively. Di and Zhu (2009c) described the male of firstly. Di et al. (2009) analysed the genus Simon, 1877 (Scorpiones: Chaerilidae) from China, described the female Pocock, 1899 firstly ( Kraepelin, 1913 was a wrong record in this paper). Di and Zhu (2010) provided the redescription of Kovařík, 2000, and reported the female for the first time. Sun, Zhu and Lourenço (2010) accommodated Lourenço, Qi & Zhu, 2005 in the genus , as a new combination (Lourenço, Qi & Zhu 2005). In the meantime, Teruel and Rein (2010) transferred Lourenço, Qi & Zhu, 2005 to the genus (Buthidae) too. Recently, Kovařík (2012) reported five new species of genus , including a Xizang species Kovařík, 2012.Until now, twenty-six scorpion species of seven genera and five families were recorded in Xizang, all of them distribute in south and the north shores of Yarlung Zangbo Jiang. All of the eight species of from China found in Xizang, 10 of 11 species of from China living in Xizang (others: Kovařík, 1994 found in Yunnan, one unnamed species of in Hubei see Di et al. 2011a), 4 of 12 species of from China found in Xizang (other 8 species in Yunnan; see Di et al. 2011b). The scientific expedition investigation of some areas of China has been finished basically which reflected in the papers (Qi et al. 2005; Shi et al. 2007; Zhang and Zhu, 2009; Di et al. 2009, 2010, 2011a and b, 2012; Sun and Sun, 2011). Followed these reports, Xizang is the richest area in China in scorpion diversity.

Comments.
Five related species with close geographical distribution, : Kraepelin, 1913, , , , and , all with 7–8 granulated cutting edges on the movable fingers of pedipalp (Bastawade, 2006; Di & Zhu, 2009; Kovařík, 2000a; Zhu, Han & Lourenço, 2008). was described by type specimen from Assam (India), its original description is poor (see Kraepelin, 1913). Kovařík (2000a: 69), who analysed the old reference, recorded three characters of : middle and lateral eyes present; 7–8 granulated cutting edges on the movable fingers of pedipalp; the anterior margin of carapace arched in males. Lourenço and Duhem (2010) thought , with few differences from , may prove to be conspecific. Both sexes of , and have anterior margin truncated,but only females of have same anterior margin of carapace as . Except with poor information, other 4 species can be identified by the key provided in this paper.Kovařík, 2012http://species-id.net/wiki/Chaerilus_wrzecionkoiChaerilus wrzecionkoi Kovařík, 2012b: 11–13, figs 62–77.Holotype, allotype and paratypes, 2 males and 2 females, China, Xizang, Tomi (Tangmai), 30 km W of Donjung, 2075 m a.s.l., 23/6/2007, leg.

Scorpiops petersii : Kovařík, 2000b: 192–194, figs 35, 42, tabs 1–3; Fet, 2000d: 494.Xizang (China); Bhutan; (Assam, Himachal, Uttar, Kashmir, Meghalaya, Sikkim) India; Pakistan.Pocock, 1893 has a simple original description. Kishida (1939: 45) recorded this species distributed in Xizang and Xikang (western Sichuan and eastern Tibet of China). Kovařík (2000b) examined the lectotype and many specimens but thought it is necessary to re-evaluate the characters used in distinguishing this species from others in the genus scorpiops (Kovařík, 2000b: 193). We cannot distinguish with (Gervais, 1843) “complex” by the diagnostic characters provided by Kovařík (2000b: 193): total length is up to 75mm; male has finger of pedipalps strongly flexed; 17 external (5 eb, 2 esb, 2 em, 4 est, 4 et) and 7, or rarely 6 or 8 ventral trichobothria on the patella; pectinal teeth number 4–9. We checked sp (1 adult and 1 immature females and 1 immature male and 1 juvenile, Lhasa, 4/7/2008, Zhiyong DI leg, kept in MHBU), its adult female: body length 80.1mm (Figs 85–101; Table 2), very strong; ventral trichobothria on patella number 7 (with other: rarely 6 or 8); pectinal teeth number 4-9; a swollen telson. Except the unusual body length can let us conjecture the specimens from Lhasa maybe , all of other features shared by and . We noticed body length is an important character but it like the pectinal teeth number and patella ventral trichobothria number, all of them are some ranges and few exceptions are normal. We can’t confirm any of these characters in one species if checked just few specimens. Here, we add it to (Gervais, 1843) “complex” group. We checked an immature female (locality is Uttaranchal, India; identified as by Kovařík). And confirm the diagnosis of as follows: (1) male chela length to width ratio about 2.6, and about 2.5 in female (see Kovařík, 2000b: tab. 1); (2) male has finger of pedipalps strongly flexed; (3) 17 external (5 eb, 2 esb, 2 em, 4 est, 4 et) and 7, or rarely 6 or 8 ventral trichobothria on the patella; (4) pectinal teeth number 4–9; (5) total length above 65mm. The first character is the key difference between and (Gervais, 1843) “complex” group.

Discussion
Twenty-six scorpion species of 7 genera and 5 families (Buthidae: (1 species), (1); Chaerilidae: (8); Euscorpiidae: (4), (10); Hemiscorpiidae: (1); Scorpionidae: (1)) were recorded in Xizang, all of them distribute in south and the north shores of Yarlung Zangbo Jiang: south of 31°N, bound on the north by the Burang - Lhasa- Maizhokunggar - Gongbo’gvamda - Bomê line (Figs 136–139). In them, 20 of 26 recorded species are endemic (76.9%).

In China, the closest area of scorpion fauna with Xizang is Yunan. Except one PageBreak sp. was found in Hubei, all of euscorpiids were found in Xizang and Yunnan. Species of the genera and are dominant, with confined distribution and not overlapped in Xizang and Yunnan. All of the species of family Chaerilidae found in China are living in Xizang. Qinghai, Sichuan and Xinjiang, are also with border on of Xizang. In Qinghai, just (Karsch, 1879) reported in its northeast (Zhu et al., 2004; Zhang & Zhu, 2009). There is no scorpion species reported in Sichuan (Zhu et al., 2004). In Xinjiang, species genera of the family Buthidae recorded ( (7 species and subspecies), (1)) (Zhu et al., 2004; Lourenço et al., 2010; Sun and Sun, 2011). (Karsch, 1879) and (Birula 1911) found in South of Gansu which also belong to Qinghai-Tibetan Plateau (Sun and Sun, 2011). We conjecture the vast area of gap of scorpion distribution in the north of Xizang and the south of Qinghai is caused by the cold and clammy climate. So the scorpion fauna of Xizang isn’t related to Qinghai and Xinjiang.In the world, the 7 genera found in Xizang were recorded distributing to the south of Xizang. Modern species of genera PageBreak, and are limited to tropical areas of South Asia and Southeast Asia, although they reached considerable altitudes in Kashmir, Nepal, and Tibet (Kovařík, 2000a, 2000b). The distribution of the species of genera , , and the close related genera of also suggest the scorpion fauna of Xizang is close to South Asia and Southeast Asia.136 Map of Xizang (China), showing the localities of the species.
