Anisogomphus koxingai Chao 1954 View in CoL
Figs. 1 (a–m)
Anisogomphus koxingai Chao (1954: 214 View in CoL , 217–218, figs 285–286, 293–298, ♂, type-loc. Taiwan); Asahina (1968: 89– 90, figs 1–3, ♀, Taiwan); Matsuki (1978: 138, 147, fig. 9, larvae, Taiwan); Lieftinck et al. (1984: 33, Taiwan; Chao (1990: 191–194, figs 1–14, Hainan, Henan, Taiwan & Yunnan); Wilson (1995a: 106–107, 115, ♂, photos, Hong Kong); Wilson (1995b: 323–324, Hong Kong; Wang (2000: 205, Taiwan, photos, male Hong Kong); Wilson (2003: 216–217, ♂, photos, Hong Kong); Wilson (2005: 129, Guangxi).
Specimens: 1 ♂, Sha Lo Tung , Hong Kong, 20 vi 1992, coll. KW ; 1 ♂ (No. 24796), Heishiding , 15 viii 2003, coll. ZX ; 1 ♀, Luofushan , 8 viii 2004, coll. KW .
Remarks: The Hong Kong and Guangdong specimens possess a pair of yellow lateral spots on the otherwise black labium and the superior appendages are slightly divaricate ( Figs. 1a & 1f). Chao (1990) uses an all black labium as a keying character for A. koxingai in his key to the Chinese Anisogomphus despite the fact that Asahina (1968) illustrates female A. koxingai from Taiwan with a pair of yellow lateral spots. All the male specimens KW has examined from Hong Kong, Guangxi and Guangdong possess slightly divaricate superior appendages, as in Fig. 1f, whereas A. koxingai from Taiwan is shown with parallel superior appendages. The anterior hamulus is illustrated in Fig. 1g and the posterior hamulus outside lateral view is shown in Fig. 1h and inside lateral view in Fig. 1i. The penile organ is shown in Fig. 1j. These figures show the same structure as Chao's (1954) drawings from similar angles and there is little doubt that the mainland and Taiwanese specimens are conspecific. The description and illustrations of Anisogomphus fujianensis Zhou & Wu (1992) are similar to or identical to mainland A. koxingai in respect of colour pattern and structure of the caudal appendages. The only significant difference is the structure of the A. fujianensis anterior hamule which is illustrated as a narrow elongate peg curved at the tip. This is exactly as it appears in situ, when viewed laterally, if the posterior appendage is not removed to reveal its broad stem.
Distribution: China (Fujian [?], Guangdong, Guangxi, Hainan, Henan, Hong Kong, Taiwan, Yunnan).
