	abstract = {The west-Palaearctic species of Cephalops and Beckerias are revised. Sixteen species are recognized including one new to science. Among the taxonomic changes proposed: C. curtifrons is considered a junior synonym of Beckerias pannonicus. The results of a phenetic and cladistic analysis are given. Berkerias is considered to be closely related to Cephalops but is still treated as a separate genus until the phylogeny of the pipunculid genera is better understood. A key and diagnostic descriptions are given for all species. The male and female terminalia and other taxonomically significant structures are illustrated. The geographical distribution is given as far as known.},

	abstract = {The phylogenetic relationships of the Schizophora with the families of the Aschiza were investigated on the basis of synapomorphies. Depending on the family, the sensory epithelium of the retinae of the compound eyes of flies consists either of populations of 2 ommatidial elements or of uniform ommatidia: duotype and monotype, respectively. Within the Cyclorrhapha, the monotype occurs exclusively in the Schizophora and Syrphoidea (= Syrphidae + Pipunculidae), whereas the duotype occurs in the remaining Aschiza. These 2 types form a plesio-apomorphous pair: on the basis of character state analysis the duotype was regarded as plesiomorphous and the monotype proved to be a synapomorphy of the Schizophora and Syrphoidea. The retinal pair was accorded a high relevance as an indicator of the the phylogenetic relationships in Cyclorrhapha owing to its special morphology and the very low probability of a parallel development of the apomorphous monotype. In this paper, the hypothesis of W. Hennig (1976) that the dorsobasal arista on the antennal flagellum in the Schizophora and Syrphoidea is a synapomorphy compared to the original apical arista was confirmed on the basis of literature studies. The monophyly of these 2 groups together, and their sister group relationship, were demonstrated in an argumentation scheme. 3 alterations of the conventional systematics of the Cyclorrhapha were undertaken: (a) the term {\textquoteright}Eumuscomorpha{\textquoteright} is introduced to designate a new monophyletic taxon of the Schizophora and Syrphoidea. (b) The remaining groups of the Aschiza are temporarily subsumed in a {\textquoteright}superfamily Platypezoidea{\textquoteright} owing to their manifestation of complementary symplesiomorphous characteristics. Until its phylogenetic character (monophyly or paraphyly) is unequivocally clarified, it remains an {\textquoteright}artificial{\textquoteright} entity. (c) The term {\textquoteright}Aschiza{\textquoteright} is for a taxon of the genealogical system no longer applicable.},
