A contribution towards checklist of fungus gnats (Diptera, Diadocidiidae, Ditomyiidae, Bolitophilidae, Keroplatidae, Mycetophilidae) in Georgia, Transcaucasia

Abstract

The fungus gnats of Georgia are studied based on 2682 specimens collected from 57 localities during 2011–2019. Altogether, 245 species are recorded including four species of Bolitophilidae, three species of Diadocidiidae, two species of Ditomyiidae, 34 species of Keroplatidae and 202 species of Mycetophilidae. 230 and 188 species are recorded from Georgia and the whole of Transcaucasia for the first time, respectively. Three new species – Sciophila georgei sp. nov., Leia katae sp. nov. and Anatella metae sp. nov. – are described including detailed illustrations of the male terminalia. Photographs are provided for an additional 38 species to highlight a variability of their general facies. Combined with earlier published data, the number of fungus gnat species in Georgia is set at 246. The estimated diversity of fungus gnats in Georgia is calculated using non-parametric methods and discussed with respect to other Western Palaearctic regions.

Every Single Specimen Counts: A New Docosia Winnertz (Diptera: Mycetophilidae) Species Described from a Singleton

“…Docosia caucasica sp. n. was represented by a single specimen, which is relatively common as 33% of Georgian species are so far known from singletons [27]. Moreover, in the Malaise trap sample containing the holotype, seven out of the eight additional Mycetophilidae species were also represented by only a single specimen.…”

“…However, in other regions of the world, Mycetophilidae are even more superficially studied and/or have been almost neglected for a long time, as is the case in Transcaucasia. The first checklist of Mycetophilidae in Georgia was published only recently, still representing probably less than half of the actual local diversity, which in turn undoubtedly includes a substantial number of undescribed species [27]. Therefore, discovery of a new species from the Lesser Caucasus in Georgia is unsurprising.…”

Diptera species, new for the Republic of Mordovia, Russia

“…Neoempheria brevilineata has been found in Russia for the first time. This insufficiently known species was originally described by Okada (1939) from Hokkaido (Japan), and subsequently recorded from Georgia (Adjara, Imereti) (Kurina, 2021). Note.…”

Contribution to the knowledge of the fauna of fungus gnats (Diptera: Bolitophilidae, Keroplatidae, Mycetophilidae) from the Republic of Dagestan

“…cies richness of this group is expected to be very high. Proof of this can be found in the excellent paper published recently by Kurina [Kurina, 2021], which quotes as many as 246 species of fungus gnats from Georgia, the neighbouring Transcaucasian country. By comparison, only scattered regional data are included in two major works on the fungus gnats of Russia by Zaitzev [Zaitzev, 1994[Zaitzev, , 2003.…”

“…By comparison, only scattered regional data are included in two major works on the fungus gnats of Russia by Zaitzev [Zaitzev, 1994[Zaitzev, , 2003. Anyone who is interested in more detailed information on the number of species known from North Caucasus, the whole of Transcaucasia, or a specific Transcaucasian country should consult the paper mentioned above [Kurina, 2021].…”
