Male buzzer midge Chironomus plumosus, copyright Didier Descouens.

Belongs within: Chironomidae.

Chironomus is a cosmopolitan genus of midges. It is distinguished from related genera by features of the male genitalia, with appendage 1 often curving or hooking or with a ventral apical knob and with a digitiform process arising distad from the microtrichiose base, and appendage 2 well developed with long setae distally. Abdominal tergites often bear dark spot and transverse bands, and the r-m area of the wing is often darkened. Larvae inhabit soft sediments and other underwater organic deposits. Depending on the species, they may require pristine to acidic or brackish water habitats (Spies et al. 2009).

Characters (from Oliver 1981): Male antenna with eleven flagellomeres. Antepronotal lobes not separated medially. Wing with crossvein r-m definitely oblique to R4+5; crossvein m-cu absent. Apex of fore tibia with inner low rounded scale that projects slightly beyond similar outer scale; hind tibia with two combs composed of basally fused spines. Male terminalia with gonocoxite and gonostylus separate; appendage 1 with basal long setae, or rarely with long setae only on apical two-thirds, without enlarged setiferous base; appendage 2 subcylindrical, longer than appendage 1, with many apical setae.
