Glumac (1968) gave the first comprehensive data. He published the list of 188 species that were collected in the whole territory of Macedonia. Later, this list was supplemented with 18 additional species (Vujic, 1995). The latest comprehensive data were given by Krpac & Ivanovski (1996) and Krpac (1997). They published a list of 3 additional species. Material and methods This paper presents the results of our investigations that included a re-determination of the Glumac collection preserved in the Macedonian Museum of Natural History. Standard methods were used during this research. The material is deposited in the collection of the Macedonian Museum of Natural History. The distribution data follow Speight (1998), Peck (1988), Vujic (1990, 1996) and Vujic & Claussen (1994). Results and discussion In the past 30 years 209 species were recorded in the fauna of hoverflies in Macedonia. The results of our additional investigations included re-determination of the Glumac collection preserved in the Macedonian Museum of Natural History and the Institute of Biology in Novi Sad where they were analyzed. This paper presents data on 13 species of 6 genera of hoverflies which are new to the fauna of Macedonia. The list below presents the general distribution of each species and its distribution in Macedonia, their visit flowers and flight period. List of species: Cheilosia antiqua (Meigen, 1822) General distribution: Europe: Ireland through to central Europe and southern Europe (former Yugoslavia) and into European parts of Russia.
