CHINA: Xinjiang: 1 male, Nalati Town[那拉提镇], Xinyuan County[新源县], 1500m, 8.VI.2014, Lu-Yu Wanget Xuan-Kong Jiangleg.; 1 female, Banfanggou[板房沟], Nanshan[南山], Urumqi City[乌鲁木齐市], 1916m, 30.V.2014, Lu-Yu Wang et Xuan-Kong Jiangleg. Inner Mongolia( Neimenggu): 1 male, Mt. Tianchishan[天池山], Arxan ForestPark[阿尔山森林公园], Arxan City[阿尔山市], Hinggan League[兴安 盟], 1110m, 3.VII.2015, Gui-Qiang Huang leg. (all SWU).
Remarks. Kishii & Jiang (1999)first recorded this species in Northeast Inner Mongolia(Ganhe Town [甘河镇], in Hulun Buir City [呼伦贝尔市]) and North Xinjiang(Habahe County [哈巴河县] and Fuyun County [富蕴县]) and treated the recorded specimens as subspecies S. m. tianshanicus; however, Schimmel et al.(2015)did not include the record. In this article, the specimens examined from Xinjiangand Inner Mongoliaconfirmed the occurrence of this species in China. The specimens from Xinjianghave a dark green metallic reflection on the elytra ( Fig. 3 A), the pronotum and abdomen are blackish brown ( Fig. 3 A–B), apex of the paramere has a small hook ( Fig. 3 C), the male ( 10.7 mm) is much smaller than the female ( 14.1 mm); while the specimen from Inner Mongoliashow some differences from the former, which has a green metallic reflection on the elytra and purple metallic reflection at the base of elytra ( Fig. 3 D), the pronotum and abdomen are black ( Fig. 3 D–E), apex of the paramere has a large hook ( Fig. 3 F), the male specimen is about 14.6 mm. FIGURE 3.A–F. Pristilophus melancholicus. A–C. male from Xinjiang: A. dorsal view; B. ventral view; C. aedeagus, ventral view. D–F. male from Inner mongolia: D. dorsal view; E. ventral view; F. aedeagus, ventral view. Scale bars 2 mm for A–B, D–E; 0.5 mm for C and F. This species is widely distributed from Europe to the Russian Far East ( Kamchatka). Historically, there were many subspecies and variations, but only three subspecies are currently recognized ( Tarnawski 1995, Cate et al.2007). According to the previous studies ( Tarnawski 1995; Kishii & Jiang 1999; Schimmel et al.2015), the population from Xinjiangbelongs to Pristilophus melancholicus tianshanicus; while the subspecies status of the population from Northeast Inner Mongolianeeds to be further confirmed, noting that the gap between the two localities measures more than 2,400 km( Fig. 4 B). Moreover, the only two specimens from Inner Mongolia( Kishii & Jiang 1999 and this study) show distinct difference in the hook of paramere (comparing with Figs. 3b and 3cshown in Kishii & Jiang (1999), the new material studied in this article has bigger hook in parameres). Since it’s a very widely distributed species, and because of the inadequate samples, it’s still difficult to verify the subspecies and clarify the variations of different populations.
