Piophilidae Macquart, 1835, is a small family of flies widely distributed in all parts of the world but more represented in the cooler temperate regions of the Northern Hemisphere. At present, there is a lack of information on the distribution of this family in the Caucasus region. In this study, the family Piophilidae, with a record of Prochyliza nigrimana (Meigen, 1826), is reported for the first time from the
South Caucasus ecoregion.

The manuscript was published by one of the invited assistant researchers of Ilia State University; Sopio Balkhamishvili. Data was retrieved under the Caucasus Barcode of Life project, during the BioBlitz in Batsara, Sakisto Lake (Tbatana Lake, Georgia).
