Corethrellidae,チスイケヨソイカ科(新称)について(Diptera:Corethrellidae)

"Chisuikeyosoika" (hairy biting midges) is a new Japanese name given to the family Corethrellidae Edwards elevated from Chaoboridae Edwards. The features of the family including morphological and biological characteristics of adults and larvae are briefly mentioned. The taxonomic status of the Japanese species of the genus Corethrella: C. japonica (Komyo), C. towadensis Okada and Harada, C. nippon Miyagi and C. urumense Miyagi are also discussed. Corethrella is probably worldwide in distribution but has been overlooked in many areas. Medical entomologists in Japan are expected to pay more attention to the hairy biting midges.
