The record by Chiang & Du, 1979: 181–182/118 is not this species. These populations need to be rechecked; some may belong to I. yooni Jeong, Kotov & Lee, 2012 , see below.

Ilyocryptus sordidus (Liéven, 1848) s. lat.

These populations need to be re-identified according to recent standards, because in the Palaearctic a series of species have long been masked under the name " sordidus " ( Kotov & Štifter 2006).

Records: Ping, 1931: 182 (Nanjing); Shen & Sung, 1962: 26 (Sanmenxia Reservior); Chiang & Du, 1979: 182 –183/119 (a pond at Yunjinghong in Xishuangbanna; provinces of Guangdong, Guangxi, Fujian, Yunnan, Guizhou and Hubei); Chen, 1983: 23 (Yichang section of Yangtze River); Chen, 1985b: 2 (Yichang); Chen, 1990b: 87 (the estuary of Tuo Jiang); Xiang & Yu (unpubl. data: Yichang and Wuhan section of Yangtze River; Tuo Jiang, Huangbai He; Dong Hu in Wuhan); as Ilyocryptus halyi by Spandl, 1925: 189 /2a–b (Guangdong Province); Du, 1973: 59 /44. Chinese populations need to be revised and compared with others.
