N. nevskajae sp. n. is similar to N. scutellatus Macq. differing from its by the considerably lesser body size and partically bare hypopyge of the male, and larger 3rd segment of the antenna. N. fatalis sp. n. differs from the known representatives of the genus by the ususally thick and long setae on the apical structrues of the male's hypopyge, and a number of other characters.10aAmur10acomparative morphology10adescription10aNephrocerus fatalis new species10aNephrocerus nevskajae new species10aNephrocerus scutellatus10aPipunculidae10aPrimorye10aRussian sfsr10aUSSR1 aChurkin, S., V.  uhttps://pipunculidae.myspecies.info/content/new-fly-species-genus-nephrocerus-diptera-pipunculidae-soviet-far-east03038nas a2200313   4500008004100000245026200041210007000303260001100373300001400384490000700398520191900405653001202324653001502336653002702351653001702378653001702395653001202412653001702424653001402441653001702455653001702472653001102489653001602500653001502516653001602531653001302547100001302560856015102573       1991                        eng d00aMorphologische indizien für das unmittelbare schwestergruppenverhältnis der Schizophora mit den Syrphoidea ('Aschiza') in der phylogenetischen systematik der Cyclorrhapha (Diptera: Brachycera). [Morphological evidence for the direct sister group  relation0 aMorphologische indizien für das unmittelbare schwestergruppenver  aLondon  a1531-15700 v253 aThe 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 'Eumuscomorpha' 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 'superfamily Platypezoidea' owing to their manifestation of complementary symplesiomorphous characteristics. Until its phylogenetic character (monophyly or paraphyly) is unequivocally clarified, it remains an 'artificial' entity. (c) The term 'Aschiza' is for a taxon of the genealogical system no longer applicable.10aAschiza10aBrachycera10acomparative morphology10acompound eye10aCyclorrhapha10aDiptera10aphylogenetic10aphylogeny10aPipunculidae10arelationship10aretina10aSchizophora10aSyrphoidea10asystematics10ataxonomy1 aWada, S.  uhttps://pipunculidae.myspecies.info/content/morphologische-indizien-f%C3%BCr-das-unmittelbare-schwestergruppenverh%C3%A4ltnis-der-schizophora-mit-
