Seventeen different species of the genus Phlebotomus are known so far from the Republic of South Africa and of South West Africa. Of these Phlebotomus adami Abonnenc, Phlebotomus meeseri de Meillon and Lavoipierre and Phlebotomus meridionalis n. sp. are newly recorded from this area. The taxonomy and distribution of all seventeen species are reviewed. Zusammenfassung Über die Phlebotomus‐Arten (Dipt.: Psychod.) Süd‐ und Südwestafrikas Von Süd‐ und Südwestafrika sind bisher 17 Phlebotomus‐Arten bekannt, von dencn P. meeseri, P. adami und P. meridionalis n. sp. neu für dieses Gebiet sind. P. schwetzi, P. zumpti und Angehörige des P. bedfordi‐Komplexes sind bisher die häuflgsten Vertreter dieser Gattung in Süd‐ und Südwestafrika. Die Taxonomie und Verbreitung der 17 Arten werden erörtert.

Five new species of the genus Dichaetomyia are described from Madagascar as Dichaetomyia ambrea sp. n., Dichaetomyia besseta sp. n., Dichaetomyia doubla sp. n., Dichaetomyia montea sp. n., and Dichaetomyia ranoa sp. n. The body colour of the five species is shiny metallic blue, green or violet and the colour combinations are similar to Dichaetomyia tristis (Zielke, 1972). The species, however, differ significantly from one another in other taxonomic characteristics which are commonly used in other genera to distinguish species.

Microfilariae of Wuchereria bancrofti and Brugia pahangi, which were inoculated into Meriones unguiculatus and Mastomys natalensis respectively, were found in the peripheral blood of the rodents until the ninth day after infection, but no microfilarial periodicity was observed. Microfilariae of W. bancrofti disappeared much faster from the peripheral blood of jirds after reinfection than after the first inoculation. Microfilariae of Dirofilaria immitis inoculated into M. natalensis and laboratory mice were recovered in the peripheral blood until the 17th day after infection and remained infective to mosquitoes. For the first few days the microfilarial periodicity observed in the rodents was similar to that observed in the donor dog, but then reversed.

Dichaetomyia scutellaris (Zielke, 1974) kann eindeutig von Dichaetomyia rangeri (Zielke, 1973) unterschieden werden und ist als eigenständige Art zu betrachten. Die Unterschiede zwischen den beiden von Madagaskar stammenden Arten werden beschrieben und in einer Tabelle erfasst. Da der Name Dichaetomyia scutellaris bereits von Dichaetomyia scutellaris Malloch, 1928 besetzt ist, wird Dichaetomyia perineta nom. nov. als Ersatz vorgeschlagen. Für die existierende Bestimmungstabelle für Madagassische Dichaetomyia Arten werden entsprechende Ergänzungen empfohlen.StichwörterDichaetomyia scutellaris, replacement name, Dichaetomyia perineta nom. nov., key.Nomenklatorische Handlungenscutellaris Zielke, 1974 (Annaria), stat. rev. previously a synonym of Dichaetomyia rangeri (Zielke, 1973)perineta Zielke, 2016 (Dichaetomyia), nom. n. pro Dichaetomyia scutellaris (Ziekle, 1974), nec Dichaetomyia scutellaris Malloch, 1928

Achanthiptera rohrelliformis (Robineau-Desvoidy, 1830) and Hydrotaea aenescens (Wiedemann, 1830), two species of the subfamily Azeliinae (Muscidae), are recorded for the first time from Bulgaria, although they have been already collected around 1908 and 1973, respectively. Due to the fact that the specimen of A. rohrelliformis has not been determined earlier and that males and females of H. aenescens have been erroneously assigned to Ophyra leucostoma (Wiedemann, 1817), the findings of the two species, new to the muscid fauna from Bulgaria and the Balkan Peninsula, are only reported now.
