Parachironomus inafegeus Sasa, Kitami & Suzuki, 2001: 6 (syn. n.). Material examined. China. ā™‚ (No. 05227) Fujian Province, Longyan City, Shanghang county, 3.v.1993, light trap, X. Wang. The type specimen of Parachironomus inafegeus Sasa, Kitami & Suzuki. Holotype, ā™‚ (No. 398: 65), on the shore of lake Inawashiro, insect net, 8.vi.2000. Diagnostic characters. Thorax yellowish brown with white stripes; anal point parallel-sided, slender; anal tergite bands "V" -shaped, not fused in the middle; superior volsella crescent-like; inferior volsella tuberculate with two small protuberances, bearing two strong apical setae, free of microtrichia. Distribution. China (Fujian Province); Russian Far East; Japan; Europe. Remarks. The holotype specimen of Parachironomus inafegeus Sasa, Kitami & Suzuki, 2001 mainly agrees with the description of Cryptochironomus albofasciatus (Staeger, 1839) by Goetghebuer (1937-195: 38, fig. 116), especially the characters of anal point, superior and inferior volsella, and gonostylus. Consequently, it must be considered a junior synonym of Cryptochironomus albofasciatus (Staeger, 1839). See also the species illustration in Yan et al. (2016 : 487, fig 1.).
