Coquillettidia is a mosquito genus erected by entomologist Harrison Gray Dyar Jr. in 1904 based primarily on unique features of its "peculiar" male genitalia. The specific epithet honors Dyar's colleague Daniel William Coquillett. The genus comprises three subgenera, Austromansonia, Coquillettidia, and Rhynochotaenia, and 57 species, of which Coquillettidia perturbans is perhaps the best known.
