The record of Ametropus fragilis Albarda, 1878 (Ephemeroptera, Ametropodidae) from Georgia

The representatives of the genus Ametropus (Insecta, Ephemeroptera) were recorded 80 years ago in Georgia. Due to the taxonomic uncertainty, the recorded specimens were considered potentially new taxa. Since then, no other record of Ametropus has been documented from the whole South Caucasus and its nearby regions further south. In the present contribution, we provide a new record of Ametropus from the Alazani River (Kura River Basin, Georgia). Morphological and DNA barcoding of the COI gene fragment showed that the species belongs to the widespread Holarctic species A. fragilis. Morpho-anatomical characteristics also confirmed the high degree of similarity between the newly recorded specimens and those once recorded 80 years ago. In addition, the COI barcode showed a strikingly closer relationship between Caucasian A. fragilis and North American A. neavei (3.54% divergence) compared to Caucasian and European A. fragilis populations (4.3% divergence). The observed pattern clearly indicates the need for further and more thorough revision of the Ametropus species complex in the Holarctic region

The first DNA-assisted record of Hemelytroblatta livida (Blattodea: Corydiidae) from Georgia with notes on Corydiinae species composition in the Caucasus

The fossorial sand cockroach Hemelytroblatta livida (Brunner von Wattenwyl, 1865) is reported from Georgia for the first time, with a commentary on the species composition of the Corydiinae Saussure, 1864 subfamily in the Caucasus. Collection data, pictures of the male and female, and DNA barcodes are also provided. Furthermore, information on Polyphaga aegyptiaca (Linnaeus, 1758) is provided, along with images of the male, female, and juvenile

New and well-forgotten: DNA-assisted records of two beetle (Insecta, Coleoptera) species new for the fauna of Georgia with an update on the distribution of some other little studied taxa

First records of two species of beetles (Insecta, Coleoptera), namely Pocadius adustus Reitter, 1888 (Nitidulidae) and Byrrhus pustulatus (Forster, 1770) (Byrrhidae) are given for Georgia. In addition, an update on the occurrences of Necrobia violacea (Linnaeus, 1758) (Cleridae), Coelostoma orbiculare (Fabricius, 1775) (Hydrophilidae) and Lycoperdina succincta (Linnaeus, 1767) (Endomychidae) are also presented based on the specimens collected in Samtskhe-Javakheti region, determined by morphological and mtDNA barcoding methods

Into the unknown: the first barcode-assisted checklist of Psocoptera (Insecta, Psocodea) of Georgia with a census on country species richness

This checklist reports 47 species of Psocoptera from 15 families and three suborders from Georgia, of which 31 species are recorded for the first time, increasing the known fauna of the country by more than 65%. Of these, 37 species have been barcoded, representing 210 Barcode Identification Numbers (BINs). An additional 14 species are expected to occur in Georgia but remain undiscovered, meaning that only ≈ 77% of the fauna is currently documented. Barcodes, comments on distributions, and images of voucher specimens are given followed by a map of the sampling sites
