Abstract
The B. bicolor group of species of the predaceous midge Bezzia Kieffer, subgenus Homobezzia Macfie, is diagnosed and a key is presented for adults of the 5 North American species, which are described and illustrated. The North American nominal species B. copiosa (Thomsen) is considered to be a junior synonym of B. bicolor (Meigen), formerly known only from Eurasia. B. fairchild sp. nov. is described from Florida [USA]. New distribution records are presented for B. bicolor and B. coloradensis, sp. and the immature stages are described and figured for 3 spp., including detailed larval habitat records. B. biannulata is also discussed.
