GEIGER Université de Provence Laboratoừe de Systématique Evolutive 3 place Victor-Hugo 13331 Marseille Cedex France Universitdt Bern Zoologisches Institut Baltzerstrasse 3 CH 3012 Bern Suisse Summary Electrophoretic techniques confirm that the papilionid butterflies Parnassius apollo and p. phasbus two sympatric taxa usually considered as distinct species display hybridization phenomena in limited areas of their range. Morphological criteria provided only presumptions and poor genetical indications. Moreover it is possible to demonstrate that some gene flow is possible between the two species. The implications for the semispecies concept and interspecific gene exchange are discussed. Key words interspecific hybrid Parnassius apollo Parnassius phoebus gene flow electrophoresis. Resume Detection électrophorétique d hybrides interspecifiques dans le genre Parnassius Lépidoptères Papilionidés Les techniques ệlectrophorétiquẹs confirment que les papillons Parnassius apollo et p. phoebus deux taxa de la famille des Papilionidés habituellement considérés comme deux espèces sympatrides bien distinctes montrent des phénomènes d hybridation dans des parties ỊỊmitệes de leurs aires. Les critềres morphologiques ne foumissaient que des présomptions inutilisables au niveau génétique. De plus il est ainsi possible de démontrer qu un certain flux génique est possible entre les deux espèces. Les implications pour le concept de semi-espèce et les Changes géniques interspécífiques sont discutées. Mots clés hybride interspecifique Parnassius apollo Parnassius phcebus flux génique electro-phorèse. I. Introduction Reports on field collected interspecific hybrids are numerous in insects. In most cases these observations have been based upon an analysis of morphological characters. Such hybrids are especially easy to detect in butterflies by .
