Ilyocryptus spinifer Herrick, 1882 . Very common, in all types of waters. Benthic, associated with muddy or clay bottom. For detailed description see Kotov & Dumont (2000). Species is cosmopolitan since no evidence of noncosmopolitanism has been found ( Kotov & Dumont 2000); common in the Oriental region including China. For list of records in China see Xiang et al. (2015).

Ilyocryptus yooni Jeong, Kotov & Lee, 2012 . Found in winter only in two ponds (loc. 15, 29) and in a single channel (loc. 16) with slow current. Benthic species, usually found in permanent lakes having broad, shallow water zones with well-developed littoral vegetation (Jeong et al., 2012). For detailed description see Jeong et al. (2012). The species is known from Far East of Russia, Japan, Korea; in China in Xingkai Hu, on border between Russia and China (Jeong et al. 2012), this suggest it can be expected everywhere in East China.
