Remarks.

Mystacides azureus is one of the most widely distributed species of the genus in Europe. It has been recorded in numerous countries, including the United Kingdom, Germany, France, Italy, and the Balkan Peninsula ( Graf et al. 2008). The species is also present in Japan, alongside two newly described species within the M. azureus species group ( Kuhara et al. 2023). In the Caucasus region, M. azureus was previously reported from Russia ( Oláh 1985; Ivanov 2011). Notably, the first photographic record of this species in Georgia was made by amateur naturalist Giorgi Makharadze, posted on the Facebook group “ Wildlife in Georgia ” in 2020.
