Notes.

The German specimens were compared with a specimen from Moldova (CNCHYM 00280) which had been identified by Kotenko in 1986 and donated to the CNC. We also ran our specimens through the keys of Tobias (1986), van Achterberg (2002), and Kotenko (2007) where they match Choeras gnarus also in accordance with Kotenko’s specimen at the CNC (CNCHYM 00280). In Abdoli et al. (2019), some of our specimens match Choeras formosus Abdoli & Fernandez-Triana, 2019 from Iran, based on the presence of a well-defined median carina on the propodeum. However, this character is variable in our specimens ranging from irregular rugosities to an incomplete to clearly defined median carina (see Fig. 8 ). In addition to morphology, our barcodes match a barcoded specimen from Moldova (CNCHYM 00280) by 100%, authoritatively identified by A. Kotenko, who is an author of the species. The presence/absence of a median carina as a character to identify species of Choeras may have to be reassessed in the future. This species is illustrated in Figs 7 - 9 .
