Genus Eurystylus Stål, 1871

E. burmanicus (Distant, 1904) (Fig. 2 E)— Distribution: China (Yunnan), India, Myanmar (Karen), Nepal* (Kathmandu Valley, Makawanpur), Thailand* (Chiang Mai).— Note: This tropical species is considered to be a closest relative of E. coelestialium (Zheng et al., 2004), from which E. burmanicus can be distinguished by the generally grayish brown body and a clear, creamy, mesal stripe on the scutellum.

E. coelestialium (Kirkaldy, 1902) — Japan (Hokkaido, Honshu, Shikoku, Kyushu, Okushiri Is., Rishiri Is., Tsushima Is., South Chishima [= Kuril] Islands), China (nearly eastern half region), Korea, Russian Far East (Khabarovsky and Primorsky), Taiwan*.— Note: This species has the northernmost distribution among the congeners, as a result of successful adaptation to cold temperate zones.

E. costalis Stål, 1871 (Fig. 2 F)—China (widely from northeast to central and southern parts), Indonesia (Java, Sumatra), Philippines, Thailand * (Nakhon Ratchasima), Pacific islands, Papua New Guinea*.

E. jingfui Yasunaga, Nakatani & Chérot, n. sp. — Taiwan (Kaohsiung).

E. luteus Hsiao, 1941 (Figs. 7, 8 B)— China (Anhui, Fujian, Guandong, Guizhou, Hainan, Jiangxi, Sichuan, Yunnan, Zejiang), Korea?— Note: What has been identified as E. luteus in Japan and Taiwan corresponds to E. sauteri. Even the northernmost specimens in North Korea (Fig. 8 B) cannot be positively separated from the holotype of E. sauteri (Fig. 8 C). Both taxa are presumed to be conspecific (see discussion below).

E. ryukyus Yasunaga, Nakatani & Chérot, n. sp. — Japan (southernmost areas of Shikoku & Kyushu, Koshiki Islands, Ryukyus: Amami, Okinawa, Ishigaki, Iriomote & Yonaguni Islands), Taiwan.

E. sauteri Poppius, 1915 — Japan (Honshu, Shikoku, Kyushu, Tsushima Island), China (Guanxi), Taiwan (Kaohsiung, Nantou).

Genus Eurystylopsis Poppius, 1911 [= Eurystylomorpha Poppius, 1915, n. syn.]

Ep. angustatus Zheng & Lu, 1995 — China (Gansu).

Ep. chinensis Zheng & Chen, 1991 — China (Sichuan, Yunnan).

Ep. clavicornis (Jakovlev, 1890) (Fig. 8 H–I, 9A–B, 10D–E)— China (Fujian, Gansu, Guandong, Guanxi, Guizhou, Jiangxi, Sichuan, Yunnan, Zejiang), Nepal *(Kathmandu Valley), Thailand * (Chiang Mai).

Ep. crassicornis (Poppius, 1915), n. comb. [Eurystylomorpha]— Taiwan (Kaohsiung, Nantou).

Ep. hirtipes Zheng & Lu, 1995 — China (Gansu).
