Recent methods for the investigation of the accessory glands of the human male genital tract

AbstractThe 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.

Male Genital

Distinct constrictions occur between and within the various parts of the male genital tract in Lepidoptera. These consist of an epithelium surrounded by a single inner circular and multiple outer longitudinal layers of muscles. The thicker muscles and the lack of a secretion serve to keep the lumina of the constrictions closed between matings. They are opened by the pressure of secretion being pushed down the tubular tract by muscular action. It is proposed that their development in Lepidoptera has made possible the evolution of accessory glands in series, rather than in parallel, in those situations in which separation of secretory products is required.
