Résumé. – Une nouvelle structure a été découverte dans les genitalia femelles des Anthene et des genres proches (Lycaenesthini, Polyommatinae), deux appendices liés à l’oviducte.

During the revision of the genus Anthene Dounbleday 1947 and allied genera (Lycaenesthini, Polyommatinae), a new structure was discovered in the female genitalia. It consists of two appendices laterally attached to the oviduct, near its distal end, and occurs in all the 150 or so species of these genera, including the Oriental species. This discovery prompted more investigations, and similar appendices were discovered in two other subfamilies. In Theclinae, they are found in the single African genus of the Cheritrini tribe (Dapidodigma), as well as in most genera of the Iolaini tribe, including two oriental genera. In Lipteninae, they occur in the genus Mimacraea (Liptenini), with a slightly different disposition. Some 150 females belonging to various other families were also examined, but no appendices were found.

A detailed study of the genera in the Mimacraea section of the Liptenini revealed three, possibly four, different types of female genitalia within the section, those of the Mimacraea, those of the Baliochila and Teriomima, without appendices, but with two strong spurs inside the abdomen, and those of the other genera (Pseuderesia and others), with two pockets, located on the internal face of the anal papillae and with openings on both sides of the ovipore. Three different types of pockets were found in these genera. The case of the genus Cnodontes, with small internal spurs and a pocket on one side only, is puzzling.
