Abstract
The paper presents information about 37 dolichopodid species, collected from 14 localities in Bulgaria. Five species (Medetera murina, Systenus scholtzi, Neurigona nubifera, Rhaphium antennatum and Sciapus bellus) are recorded for the first time for the fauna of Bulgaria. The species S. scholtzi is new to the Balkan Peninsula and the genus Systenus is a new genus of the family Dolichopodidae for the Bulgarian fauna.
Highlights
The family Dolichopodidae encompasses small- to middle-sized species (1 to 10 mm)

The main purpose of this paper is to provide new records of the family Dolichopodidae for Bulgaria and data on the distribution of the dolichopodids in poorlystudied areas in the country
Summary
The family Dolichopodidae encompasses small- to middle-sized species (1 to 10 mm). The flies of the family, called long-legged flies, are predators and among their food sources are small invertebrates as ticks, insects (imago and larvae), worms and etc. The adults dwell in humid habitats around rivers, ponds, marshes, lakes and sea shores and rocks, and are found in deciduous and coniferous forests. Their body is most often metallic-green but in some species could be yellow or blue. About 8 000 different species are described worldwide, excluding Antarctica. In Bulgaria, 204 species are known up to now (Kechev et al, 2020; Kechev & Glogov, 2021; Kechev, 2021)
