FOLIA ENTOMOLOGICA HUNGARICA ROVARTANI KÖZLEMÉNYEK Volume 64 2003 pp. 267-276. Contributions to the taxonomy of Afrotropical Eudorylini (Diptera, Pipunculidae) M. FÖLDVÁRI Abstract: Two new pipunculid species (E. tanzaniensis sp. n., E. amani sp. n.) from the Afrotropical Region are described, Eudorylas aculeatus (Loew, 1858) is redescribed with detailed drawings of male and female genitalia and remarks on species identity as partial results of the taxonomic revision of Afrotropical Eudorylini. Key words: Pipunculidae, Eudorylini, Eudorylas, taxonomy, new species, Afrotropical Region INTRODUCTION The fly family Pipunculidae is the closest relative of the Syrphidae (hoverflies), and it can easily be differentiated from the latter by the wing venation (no vena spuria, open r

5 cell) and by the (sub)hemispherical head being largely occupied by the compound eyes (De Meyer 1989). During the larval stage they are endoparasitoids of Auchenorrhyncha (Homoptera). The Eudorylini tribe contains the most species (over 400) within the family, and its taxonomy is confusing because of the insufficient descriptions of earlier authors, who did not investigate characters of the male genitalia, and did not publish drawings detailed enough, and also because of the lack of a genus-level revision with study of the definition and limits of e.g. Eudorylas. To resolve the taxonomic problems of this group more research and comparative study of types is necessary. Recently Skevington & Yeates (2001) classified the tribe based on morphological characters and a phylogenetic analysis of species from every Zoogeographie region (and described two new genera, Clistoabdominalis and Dasydorylas). Now a detailed revision of the regions' species is needed, among others, that of the Afrotropical fauna, which is in progress. During the studies of the relevant material of different museums from all over the world several new species have been found and three of them will be described in this paper.
