Belongs within: Culicomorpha.
The Chaoboridae, phantom midges, are a cosmopolitan group of small, delicate flies with aquatic larvae found in standing freshwater habitats. The Nearctic Eucorethra underwoodi possesses a long clypeus, nearly as long as the rest of the head capsule, whereas the clypeus is shorter in the remaining Chaoborinae (Cook 1981).
Characters (from Cook 1981, as Chaoborinae): Clypeus with numerous setae, shorter than two-thirds height of rest of head capsule. Lateral lobes of postpronotum separated medially by scutum and antepronotum. R1 terminating in C near wing apex, nearer to R2 than Sc. Larva with thorax rounded laterally; anal segment with longitudinal fan-like row of bristles; siphon absent or as long as anal segment, with pointed apex.
