Picking pearls from the Silk Road: Insights into the spider (Arthropoda, Araneae) diversity in Georgia from the CaBOL project. Part I

Abstract

Spiders collected during field trips and by spontaneous hand-collecting throughout Georgia between the years 2006 and 2022 were determined to species level and partly characterized by genetic barcoding of the COI gene. Among the resulting 51 species, two are recorded for the first time from the entire Caucasus Ecoregion: Pireneitega armeniaca (Brignoli, 1978) (Agelenidae) and Leviellus caspicus (Simon, 1889) (Araneidae). Five species are reported for the first time from Georgia: Lycosoides coarctata (Dufour, 1831) (Agelenidae), and from the Araneidae: Aculepeira talishia (Zawadsky, 1902), Gibbaranea gibbosa (Walckenaer, 1802), G. omoeda (Thorell, 1870), Leviellus stroemi (Thorell, 1870) and Singa semiatra L. Koch, 1867. Additionally, Lycosoides lehtineni Marusik & Guseinov, 2003 syn. nov. is synonymized with Lycosoides coarctata (Dufour, 1831). Diagnostic drawings and photographs are provided.
