Abstract

New and additional faunistic records for 13 species of Dolichopodidae were given from Azerbaijan and Georgia. The species richness of Azerbaijan increased to 92 taxa as Sybistroma transcaucasica (Stackelberg, 1941) and Thinophilus quadrimaculatus Becker, 1902 are the new records for the Azerbaijan territory. Campsicnemus marginatus Loew, 1857, Sybistroma transcaucasica (Stackelberg, 1941) and Tachytrechus hamatus Loew, 1871 are recorded for the first time in Georgia and the species diversity increased to 74 taxa. and additional faunistic records for 13 species of Dolichopodidae were given from Azerbaijan and Georgia.

Introduction

The Transcaucasian region is one of the 35 richest and most endangered sites in the world (“biodiversity hotspots”) with an extraordinary diversity of endangered and endemic species (Myers et al. 2012). However, the Diptera diversity of the Transcaucasian area (Armenia, Azerbaijan, and Georgia) is insufficiently investigated (Oboňa et al. 2017).

According to the authors knowledge, 90 species of the long-legged flies are recently known from territory of Azerbaijan (Negrobov et al. 2020) and 71 species – from territory of Georgia (Negrobov et al. 2020.). This paper summarizes our new and additional faunistic records.

Material and methods

Dipterans were collected by sweep netting from the vegetation growing along the watercourses and lakes by the members of V4 & Eastern Partnership team (Visegrad Group + Georgia and Azerbaijan - abbreviated as V4 & EP leg.) in April 26–May 10, 2019. The captured specimens were preserved in 75% ethanol directly in the field. The material is deposited in the collection of the first author Oleg P. Negrobov (Voronezh University, VU), who also identified these species. Distribution information is given only for the new country records according to Grichanov (2007).

Conclusion

The present records of Sybistroma transcaucasica (Stackelberg, 1941) and Thinophilus quadrimaculatus Becker, 1902 increases the Azerbaijan species richness from 90 taxa (Negrobov et al. 2020) to 92 taxa. The records of Campsicnemus marginatus Loew, 1857, Sybistroma transcaucasica (Stackelberg 1941) and Tachytrechus hamatus Loew, 1871 increases the Georgian species diversity from 71 taxa (Negrobov et al. 2020) to 74 taxa.
