Comparative morphology of the last gastral segments and male genitalia of Vespidae Masarinae (Hymenoptera). This paper is the second part of a more general investigation of the comparative morphology of vespid male genitalia. It provides a description and morphological interpretation of the last gastral segments and of the male genitalia of several species of Ceramius and Celonites, also of Jugurtia dispar and Masaris vespiformis, emphasizing the great diversity of the different structures (basal ring, gonocoxites or parameres, volsellae and aedeagus) within the subfamily Masarinae. The detailed morphological characteristics of the male genitalia, combined with observations of their chetotaxy, should provide important taxonomic characters.
Le présent article propose une description des derniers segments du gastre et des genitalia mâles de plusieurs espèces de Ceramius et de Celonites, ainsi que de Jugurtia dispar et de Masaris vespiformis, faisant ressortir la grande diversité des structures (anneau basal, gonocoxites, volselles, aedeagus) au sein de la sous-famille des Masarinae. Les caractéristiques morphologiques détaillées de ces diverses structures, jointes à l'étude de la chétotaxie, doivent fournir des données précises utilisables en systématique.
