Abstract

Summary L. Tsacas & R. Desmier de Chenon: Taxonomy and distribution of the « Genera » Cacoxenus - Paracacoxenus - Gitonides - Gitona [Diptera, Drosophilidae] and biology of a new African species, commensal of Apoidea [Hymenoptera]. After a morphological, biological and biogeographical study of this « genera » the following system is adopted: the genera Gitona Meigen and Cacoxenus Loew are maintained; Cacoxenus is subdivided into three subgenera: Cacoxenus s. str., Paracacoxenus Hardy nov. comb., and Gitonides Knab nov. comb. A lectotype is designated for Gitona distigma Meigen and its genitalia figured. The synonymy Gitona paoli Séguy, 1933 = Cacoxenus (Gitonides) perspicax Knab, 1914 is established. Gitona frontalis Collart, 1935 and G. vlasovi Duda, 1934 are transfered to the genus Cacoxenus subgenus Gitonides. Drawings of the genitalia of these two species are given. Cacoxenus (Gitonides) apidoxenus, sp. n. from Africa is described. The distribution of C. (G.) perspicax extends over three continents, it follows the expansion of its principal host Saccharicoccus sacchari Coquerell. C. (G.) apidoxenus, sp. n. is widely distributed in Western and Central Africa. It appears that the main limiting factor of its distribution is the ecological conditions of the attacked Hymenopteran nest and not the general climatic conditions of the region. It should be the same concerning the relationship with its hosts. The theoretical and practical consequences of the distribution and the biology of the species of the subgenus Gitonides of the genus Cacoxenus are discussed.
