Moth flies (Diptera: Psychodidae) of Abkhazia (western Caucasus, Georgia) with some additional faunistic data from Armenia, Georgia, and Russia

Abstract

This paper attempts to fill the knowledge gaps in biodiversity of non-biting moth flies in the Caucasus (especially in Abkhazia) and create a suitable basis for subsequent (not only) ecological studies. In total, records of 65 Psychodidae (Sycoracinae - one sp., Psychodinae 64 spp., altogether 33 genera) species/subspecies are presented based on specimens collected mainly in Abkhazia, with some additional data from Armenia, Georgia, and Russia (12 new records). The Psychodidae fauna of Abkhazia now comprises 57 species, 31 of which are newly listed here. The Caucasus region (including the territory of Abkhazia presented here) should be considered the most biologically rich and most endangered region in the world, with an exceptional richness of endemic and endangered species also from the point of view of psychodids biodiversity. Sixteen extremely rare species in this family (probably Caucasus or highland endemics) which need to be given increased attention, whether from the point of view of island ecology or biodiversity protection, have been herein confirmed.
