摘要：

The male genital tract of Chaoboridae, represented by Eucorethra underwoodi Underwood, Mochlonyx velutinus (Ruthe), and Chaoborus trivittatus (Loew), is described for the first time. All genera have paired accessory glands that are attached anteriorly to the vasa deferentia or the base of the testes, a feature that is proposed as a synapomorphy of Chaoboridae + Culicidae. Mochlonyx Loew and Chaoborus Lichenstein have distinctive pigment cells covering their testes and a portion of the vasa deferentia. The simplified male genital tract of Corethrellidae + Chaoboridae + Culicidae is correlated with the virtually unique abrupt and permanent 180 degrees rotation of the male genitalia between segments 7 and 8. In taxa with an accessory-gland complex, the male genitalia are rotated in a more gradual manner, often during copulation.
