A review of the Japanese Cryptochironomus Kieffer, 1918 (Diptera, Chironomidae)

Abstract

The genus Cryptochironomus Kieffer, 1918 from Japan is reviewed based on material composed of male adults. New combinations of three species are established and they are re-described based on male adult of: C. misumaiprimus (Sasa & Suzuki, 1998), comb. n., C. tokaraefeus (Sasa & Suzuki, 1995), comb. n. and C. tonewabeus (Sasa & Tanaka, 2002), comb. n. Additional taxonomic notes are also provided: C. albofasciatus (Staeger, 1839), which is a senior synonym of Parachironomus inafegeus Sasa, Kitami & Suzuki, 2001 and C. rostratus (Kieffer, 1921) as the senior synonym of Paracladopelma inaheia Sasa, Kitami & Suzuki, 2001. A key to the known adult males of the genus from Japan is given.
