Remarks. The taxonomic status of E. setosus rubicundus Gusenleitner, 1994 described from Oman remains unclear.

Field observations. Similar to Chlorodynerus arenicola, females of E. setosus were observed at Glycyrrhiza triphylla at Tamdytau Mountains, Kyzylkum Desert, but the latter wasp species mainly robbed nectar from flowers that have not yet fully opened (Fig. 2B, C). In addition, females sometimes did regular visits to open flowers (Fig. 2D), as well as a secondary nectar robbing (sensu Inoyue 1980) from buds already gnawed out by Ch. arenicola . Opening flowers that have not yet fully opened is known in some species of the pollen-wasp genus Celonites Latreille but in the latter case the wasps use such flowers rather to uptake pollen than nectar (Mauss & Müller 2014; Fateryga et al. 2023b).
