Abstract

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.

Introduction

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 and 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.

Scorpiops tibetanus 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: Chaerilus tryznai Kovařík, 2000 (Chaerilidae); Scorpiops margerisonae Kovařík, 2000 and 1 new record: Scorpiops hardwickii (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: Heterometrus petersii (Thorell, 1876) (Scorpionidae) and Scorpiops petersii Pocock, 1893. From 2005, much more work on Xizang was finished. Kovařík (2005) described Euscorpiops novaki 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 (Chaerilus) and Euscorpiidae (Euscorpiops and Scorpiops): Scorpiops atomatus Qi, Zhu & Lourenço, 2005; Scorpiops langxian Qi, Zhu & Lourenço, 2005; Scorpiops luridus Qi, Zhu & Lourenço, 2005; Scorpiops pococki Qi, Zhu & Lourenço, 2005; Euscorpiops karschi Qi, Zhu & Lourenço, 2005; and Chaerilus tessellatus Qi, Zhu & Lourenço, 2005. Lourenço, Qi and Zhu (2005) identified Mesobuthus songi Lourenço, Qi & Zhu, 2005 (Buthidae), and Heterometrus tibetanus Lourenço, Qi & Zhu, 2005. Lourenço and Qi (2006) established of a new genera by specimens from Xizang: Tibetiomachus Lourenço & Qi, 2006 (Hemiscorpiidae) and new species: Tibetiomachus himalayensis Lourenço & Qi, 2006. Bastawade (2006) reported 2 new species and 4 new records: Chaerilus dibangvalleycus Bastawade, 2006; Chaerilus pictus (Pocock, 1890); Chaerilus tricostatus Pocock, 1899; Euscorpiops asthenurus (Pocock, 1900); Euscorpiops kamengensis Bastawade, 2006; Scorpiops leptochirus Pocock, 1893 by the specimens from South Xizang (China). Lourenço and Zhu (2008) discovered a new species belonging to Isometrus (Buthidae): Isometrus (Reddyanus) tibetanus Lourenço & Zhu, 2008, at the same time, Isometrus was a new recorded genus to Xizang. Zhu, Han and Lourenço (2008) summarized the chaerilid scorpions of China, and provided the redescriptions for Chaerilus tessellatus Qi, Zhu & Lourenço, 2005 and Chaerilus triznai Kovařík, 2000; pointed out that Chaerilus pictus (Pocock, 1890) which was described by Qi et al. (2005) was misidentified, and described one new species: Chaerilus conchiformus Zhu, Han and Lourenço, 2008, all of them from Xizang. Di and Zhu (2009a and b) established 2 new species: Scorpiops lhasa Di & Zhu, 2009 and Chaerilus mainlingensis Di & Zhu, 2009 successively. Di and Zhu (2009c) described the male of Euscorpiops karschi firstly. Di et al. (2009) analysed the genus Chaerilus Simon, 1877 (Scorpiones: Chaerilidae) from China, described the female Chaerilus tricostatus Pocock, 1899 firstly (Chaerilus assamensis Kraepelin, 1913 was a wrong record in this paper). Di and Zhu (2010) provided the redescription of Scorpiops margerisonae Kovařík, 2000, and reported the female for the first time. Sun, Zhu and Lourenço (2010) accommodated Mesobuthus songi Lourenço, Qi & Zhu, 2005 in the genus Hottentotta, as a new combination Hottentotta songi (Lourenço, Qi & Zhu 2005). In the meantime, Teruel and Rein (2010) transferred Mesobuthus songi Lourenço, Qi & Zhu, 2005 to the genus Hottentotta (Buthidae) too. Recently, Kovařík (2012) reported five new species of genus Chaerilus, including a Xizang species Chaerilus wrzecionkoi 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 Chaerilus from China found in Xizang, 10 of 11 species of Scorpiops from China living in Xizang (others: Scorpiops jendeki Kovařík, 1994 found in Yunnan, one unnamed species of Scorpiops in Hubei see Di et al. 2011a), 4 of 12 species of Euscorpiops 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, Chaerilus assamensis: Kraepelin, 1913, Chaerilus conchiformus, Chaerilus dibangvalleycus, Chaerilus mainlingensis, and Chaerilus tryznai, all with 7–8 granulated cutting edges on the movable fingers of pedipalp (Bastawade, 2006; Di & Zhu, 2009; Kovařík, 2000a; Zhu, Han & Lourenço, 2008). Chaerilus assamensis 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 Chaerilus assamensis: 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 Chaerilus tryznai, with few differences from Chaerilus assamensis, may prove to be conspecific. Both sexes of Chaerilus conchiformus, Chaerilus dibangvalleycus and Chaerilus tryznai have anterior margin truncated, but only females of Chaerilus mainlingensis have same anterior margin of carapace as Chaerilus dibangvalleycus. Except Chaerilus assamensis with poor information, other 4 species can be identified by the key provided in this paper.

Chaerilus wrzecionkoi are closest with Chaerilus mainlingensis Di & Zhu, 2009 and Chaerilus tryznai Kovařík, 2000. Both have manus and patella of pedipalp narrower and longer than other congeneric species. Chaerilus mainlingensis has four distinct carinae on the seventh sternite; Chaerilus wrzecionkoi has the seventh sternite granulated but without carinae; manus of pedipalp in male narrow and long, chela length/width ratio in male higher than 3 in Chaerilus tryznai Kovařík, 2000, while manus of pedipalp in male robust and chela length/width ratio in adults lower than 2.6 in Chaerilus wrzecionkoi (see Kovařík, 2012).

Comments.

Kovařík & Ahmed (2009: 10) provided a list of Scorpiops hardwickii (Gervais, 1843) “complex”, which included 12 species, containing Scorpiops atomatus. Di et al. (2011a) summarized the characters of Scorpiops hardwickii “complex” and excluded Scorpiops atomatus with the reasons as followed: (1) pectinal teeth count is 9–11 in Scorpiops atomatus, and 4–8 in Scorpiops hardwickii (Kovařík, 2000: 178); (2) ventral trichobothria on patella number is 9 in Scorpiops atomatus, and 6–8 in Scorpiops hardwickii (Kovařík, 2000: 176); (3) fulcra are present in Scorpiops atomatus but absent in Scorpiops hardwickii. In addition, Scorpiops atomatus has clearly thinner chela than Scorpiops pococki and Scorpiops langxian.

Comments.

Scorpiops luridus is the absolute offbeat member of Scorpiops: large body, pale yellow color, strong chelas and swollen telson. We checked other specimens (1 male and 1 female, from Shannan Prefecture, Xizang) and the type specimens, confirmed the distinctive color of this species not because of the immature age after molting.

Habitat.

Found under stones.

Distribution.

Nang County, Nêdong County (Naidong district) (China).

Comments.

Scorpiops margerisonae was establishedby Kovařík (2000b) just using 1 male specimens. Its most important character provided by Kovařík (2000b) is the highest numer of pectinal teeth (12–13). Although the original description is poor, we can find another valuable information: Scorpiops margerisonae has a pair strong chelas with rectangular manus (with big granules in surface). Di & Zhu (2010) redescribed Scorpiops margerisonae and reported its female for the first time, and changed its pectinal teeth numer characters as a range 8–10 in females, 9–13 in males.

Comments.

Scorpiops petersii 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 Scorpiops petersii with Scorpiops hardwickii (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 Scorpiops 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 85101; 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 Scorpiops petersii, all of other features shared by Scorpiops hardwickii and Scorpiops petersii. 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 Scorpiops hardwickii (Gervais, 1843) “complex” group. We checked an immature female (locality is Uttaranchal, India; identified as Scorpiops petersii by Kovařík). And confirm the diagnosis of Scorpiops petersii 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 Scorpiops petersii and Scorpiops hardwickii (Gervais, 1843) “complex” group.

Material examined.

1 female and 5 juveniles, China, Xizang, Shigatse City, around the Zhabulun Temple, 13/8/2006, Xiao-Feng Yang leg, (MHBU, Ar.- MHBU - XZSH0601–6).

Diagnosis.

Adult body length about 45–65 mm. Mainly color uniformly reddishblack. Male has finger of pedipalps more flexed and manus shorter and broader than the female. 17 external trichobothria (5 eb, 2 esb, 2 em, 4 est, 4 et) and 7–10 ventral trichobothria (usually 9) on the patella. Pectinal teeth number 5–11.

Comments. In Kovařík & Ahmed’s list of Scorpiops hardwickii (Gervais, 1843) “complex” (2009: 10): containing Scorpiops tibetanus Hirst, 1911. Hirst (1911) did not provide a detailed description except the brief comparison with Scorpiops austerus Hirst, 1911 (synonymized with Scorpiops hardwickii by Tikader & Bastawade, 1983: 418) and Scorpiops crassimanus Pocock, 1899 (synonymized with Scorpiops hardwickii by Kovařík, 2000b: 175). Kovařík (2000b) examined the holotype (male) of Scorpiops tibetanus and recorded some important information: (1) total length is 50–65mm; (2) male has finger of pedipalps more flexed and manus shorter and broader than the female; (3) 17 external trichobothria (5 eb, 2 esb, 2 em, 4 est, 4 et) and 7–10 ventral trichobothria (usually 9) on the patella; (4) pectinal teeth number 5–11. Di et al. (2011a) excluded Scorpiops tibetanus from Kovařík’s Scorpiops hardwickii “complex” as followed reasons: (1) ventral trichobothria on patella in S. tibetanus number 7–10 (usually 9, in one young out of 37 specimens, 7 on one side; Kovařík, 2000b: 196), 6–8 in Scorpiops hardwickii “complex”; (2) pectinal teeth number is 5–11 (usually 7–11) in Scorpiops tibetanus, 4–9 in Scorpiops hardwickii (usually 5–7).

Description.

(based on female specimens: Ar.- MHBU - XZSH0601).

Coloration: red brown mainly.

Discussion

Twenty-six scorpion species of 7 genera and 5 families (Buthidae: Hottentotta (1 species), Isometrus (1); Chaerilidae: Chaerilus (8); Euscorpiidae: Euscorpiops (4), Scorpiops (10); Hemiscorpiidae: Tibetiomachus (1); Scorpionidae: Heterometrus (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 Scorpiops sp. was found in Hubei, all of euscorpiids were found in Xizang and Yunnan. Species of the genera Scorpiops and Euscorpiops 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 Mesobuthus martensii martensii (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 (Mesobuthus (7 species and subspecies), Razianus (1)) (Zhu et al., 2004; Lourenço et al., 2010; Sun and Sun, 2011). Mesobuthus martensii martensii (Karsch, 1879) and Mesobuthus eupeus mongolicus (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 Chaerilus, Euscorpiops and Scorpiops 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 Hottentotta, Isometrus, Heterometrus and the close related genera of Tibetiomachus also suggest the scorpion fauna of Xizang is close to South Asia and Southeast Asia.
