Abstract

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° 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.

Résumé

La région génitale mâle de Chaoboridae, représentée par Eucorethra underwoodi Underwood, Mochlonyx velutinus (Ruthe), et Chaoborus trivittatus (Loew), est décrite pour la première fois. Tous les genres ont des glandes accessoires appariées qui sont attachées antérieurement au canal déférent ou à la base des testicules, un trait qui est proposé en tant que synapomorphie de Chaoboridae + Culicidae. Mochlonyx Loew et Chaoborus Lichenstein ont des cellules pigmentées distinctives recouvrant leurs testicules et une partie du canal déférent. La région génitale mâle simplifiée de Corethrellidae + Chaoboridae + Culicidae est corrélée à l’unique rotation de 180°, abrupte et permanente, des organes génitaux masculins entre les segments 7 et 8. Dans les taxa avec un complexe de glandes accessoires, les organes génitaux mâles sont tournés d’une manière plus graduelle, souvent pendant la reproduction.
