Zur systematischen Stellung mesozoischer und tertiärer Mecopteren einschließlichEoses triassica Tindale (angeblich Lepidoptera) (Insecta, Holometabola)Willmann, Rainer

Eoses triassica Tindale, by many authors regarded as the oldest representative of the Lepidoptera, is a member of the order Mecoptera.Orthophlebia reticulata (Handlirsch 1906), andO. latipennis (Handlirsch 1906) from the Upper Lias of Mecklenburg (Germany) are synonyms ofO. Limnophila (Handlirsch 1906).O. elegans (Handlirsch 1939) is a synonym ofO. vicina (Handlirsch 1939). TheOrthophlebioides-problem is discussed in the light of Handlirsch’s argumentation. Contrary to Handlirsch’s opinion this genus represents the hind wings ofOrthophlebia as previous authors suggested. Reasons are offered for the synonymy ofSynorthophlebia withOrthophlebia andMesopanorpa, respectively.Limfiordia from the Mo-clay of the Limfjord area (Denmark) is not a scorpion-fly but a member of the Fulgoriformes (Auchenorrhyncha).Parachorista Lin 1976 (nom. praeocc, nonParachorista Tillyard 1926) from the Jurassic of China does not belong to the Orthophlebiidae (Mecoptera) but to the Trichoptera.
Revision des evolutionsdenkens?Neuchatel, Jurgen

My criticism of the »organism-centered concept of evolution« as exposed once again by Bonik et al. (this vol.) refers to its phylogenetic application but not to the underlying basic assumption. The misunderstanding is due to the fact that Bonik et al. do not distinguish between evolutionary theory (which is concerned with general problems) and phylogenetic research. Nobody would deny that organisms are energy converting systems. Variants with increased energetic efficiency will of course be favoured by natural selection. But this premise alone does not allow to reconstitute phylogenetic lineages. Evolutionary success of a given variant is determined by many other factors as, for instance, the presence or absence of certain predators. Therefore phylogenetic research depends largely on circumstantial evidence from compared anatomy. Finally it should be stressed that the elimination of »abnormal ontogenetic stages« does not contribute to phylogenetic transformation. Bonik et al. are wrong when they believe that this kind of internal selection constitutes a new, hitherto neglected element which necessitates a fundamental revision of evolutionary theory.
Deux Lepidosirenidae (Dipnoi) crétacés du Sahara,Protopterus humei (Priem) etProtopterus protopteroides (Tabaste)Martin, Michel

Zwei Arten von Ceratodontiformes werden in die GattungProtopterus Owen (Lepidosirenidae) eingeordnet.Protopterus humei (Priem) (Unterkreide bis Paleozän) undProtopterus protopteroides (Tabaste) (Unterkreide bis Oberkreide) sind nur aus Afrika bekannt. Die Unterscheidung zwischenP. humei undP. protopteroides ist manchmal sehr schwierig. Daraus ist zu schließen, daß diese zwei Arten Schwestergruppen sind. Einige Zahnplatten vonNeoceratodus africanus (Haug) sind jenen vonP. humei sehr ähnlich. Diese Arten dürfen phylogenetisch also sehr nahe verwandt sein.P. humei undP. protopteroides waren wahrscheinlich Süßwasserbewohner. Das spricht dafür, daß die Lepidosireniden vor der Trennung der beiden Kontinente (Unterkreide) von Afrika nach Südamerika gewandert sind.
