Family Leptodoridae Lilljeborg, 1861

Leptodora kindtii (Focke, 1844) . Records: Chen & Hu, 1988: 32 (Xinjiang); currently, the only trustworthy record (confirmed by DNA analysis) is from Ulungur Hu in Xinjiang (Xu et al. 2011). All other Chinese records need checking, since these populations may belong to L. richardi or hybrids L. richardi x L. kindtii (Xu et al. 2011) .

Leptodora richardi Korovchinsky, 2009 . Records: cited from various localities in China under the name L. kindtii ; Uéno, 1937: 208 (Non-ho (viz Nen Jiang) near Qiqihar); Uéno, 1940b: 552 (Ulungur Hu; Xingkai Hu=Lake Khanka); Mashiko, 1951b: 141 (Hankou, Dongting Hu); Chiang, 1955: 109/IV: 31 (Wuli Hu); Du & Lai, 1958: 29/ X: 22 (Tai Hu); Du & Lai, 1959: 305 (Tai Hu); Chiang & Du, 1979: 80–82/54 (Wuli Hu; Dong Hu in Wuhan; provinces of Zhejiang, Jiangsu, Anhui, Jiangxi, Hubei, Jilin, Heilongjiang, Yunnan and Inner Mongolia); Xu et al., 2011(Feilaixia reservoir, Qiandao Hu, Xinlicheng area; Liuxihe reservoir, Xujiahe reservoir); Xiang & Yu (unpubl. data: Zhijiang, Jianli, Chenglingji, Honghu, Jiayu, Wuhan, Huangshi, Jiujiang, Hukou, Anqing, Tongling, Wuhu, Maanshan, Nanjing and Nantong sections of Yangtze River; Xiang Xi, Huangbai He and Han Jiang; Lushui Reservoir; Bao’an Hu, Dong Hu in Wuhan, Hong Hu, Poyang Hu, Tai Hu, Biandan Tang, Wuli Hu, Dongqian Hu, Qiandao Hu and Longhu Pao). Towards the south, it reaches the Tropic of Cancer in China, much further south than L. kindtii in Europe. The records of Leptodora in China are shown in Figure 2 , however, most of these records beg morphological as well as genetical confirmation. Millette et al. (2011) confirmed the existence of two species in the Eastern Palaearctic, but did not mention any hybrids. Genetical studies of Leptodora need to be continued.
