Barcoding.

A single barcode was obtained from the specimen with CaBOL-ID 1010385 (BOLD:AEG2795) identical to the nearest neighbor in the BOLD Systems L. ustulatus (Eversmann, 1850) from Georgia, Abastumani (BOLD:AEG2795).

Remarks.

Libelloides ustulatus was synonymized with L. hispanicus Rambur, 1842, by Navás (1912). Due to the extraordinary morphological similarity of the Libelloides hispanicus and Libelloides ustulatus taxa, convergence at the subspecies level was postulated ( Aspöck et al. 1980). At the same time, due to the disjunctive nature of the distribution of these two species, some authors raise L. hispanus ustulatus to the species level ( Aspöck and Aspöck 1994; Szirák 1998; Aspöck et al. 2001; Canbulat 2007). Libelloides ustulatus is a species with a Caucaso-Anatolian distribution (Dobosz et al. 2017; Dobronosov et al. 2023). Unlike other local owlfly species, L. ustulatus occurs mainly in forest meadows at higher altitudes. For species distribution within the country, see Fig. 12.
