Contribution A l'Étude des Diptères Sarcophagidés Acridiophages. XIII. — Biotaxonomie de Blaesoxipha Grylloctona Loew 1861.: Nouvelles Réflexions sur la Systématique de ce Genre et les Méthodes d'Investigation

Abstract

Summary (*) Our contribution XIII is devoted to the biotaxonomic study of the Blaesoxypha grylloctona Loew 1861 in the sense of Villeneuve 1911.

This method being necessary to realize the right specific linkage of both sexes and the filiation of various larvous and adult stages. By this method we have achieved to define this species valuably and to distinguish it from gladiatrix (Pandellé) Villeneuve 1911, with which it was most of the time confused in the literature and collections. The ♂ particularly are so similar on the morphological plane that the specific meaning of the few minor differences between them had to be proved by biological tests. A critic examination of the bibliography has been done, the synonimic and nomenclatural problems discussed over.
