Additional data to the Hoverfly fauna of South West Bulgaria (Diptera: Syrphidae)

Abstract

The current paper publishes the faunistic data of the hoverflies collected in South West Bulgaria, mainly in the area of Pirin, Rila, Rodope and Vitosa by Hungarian entomologist. The vast majority of the data was collected by the author. The paper reports the occurrence of 269 species on the 24 points of the examined area. The search for the checklist of the Bulgarian species was unsuccessful. The author is in the knowledge of only one paper that works with the Bulgarian fauna, which contains information on the occurrence of 117 species of Hoverflies in South West Bulgaria (Bánkowska 1967). These species are marked with a star in the listing. Out of these, all have occurred during the collection by the Hungarian entomologist. The “Catalogue of Palaearctic Diptera” series, 8th volume (Peck 1988) can be considered as the most strongpoint on the fauna of the Bulgarian hoverflies. Based on this, 24 species can be considered new to the Bulgarian fauna: Brachyopa testacea (Fallén, 1817), Brachypalpus chrysites Egger, 1859, Cheilosia crassiseta Loew, 1859, Cheilosia hypena (Becker, 1894), Cheilosia insignis Loew, 1857, Cheilosia laticornis Rondani, 1857, Cheilosia pictipennis Egger, 1860, Cheilosia ranunculi Doczkal, 2000, Eumerus pulchellus Loew, 1848, Eumerus sogdianus Stackelberg, 1952, Merodon avidus (Rossi, 1790), Merodon nigritarsis Rondani, 1845, Merodon spinitarsis (Paramonov, 1929), Myolepta nigritarsis Coe, 1957, Neoascia unifasciata (Strobl, 1898), Paragus finitimus Goeldlin de Tiefenau, 1971, Paragus majoranae Rondani, 1857, Pipizella divicoi (Goeldlin de Tiefenau, 1974), Sphaerophoria taeniata (Meigen, 1822), Syrphocheilosia claviventris (Strobl, 1909), Syrphus nitidifrons Becker, 1921, Syrphus sexmaculatus (Zetterstedt, 1838), Temnostoma bombylans (Fabricius, 1805), Xylota meigeniana Stackelberg, 1964.
