Remarks.

Amolin and Artokhin (2014) stated that this species was common in Tyva Republic (Tannu-Ola) but did not report any examined specimens; that record was then disregarded by Antropov and Fateryga (2017), who did not list Tyva Republic in the distribution of E. tripunctatus . The species is well known to be confined to sandy habitats ( Amolin and Artokhin 2014), that is evident also for both the Crimea (Fig. 24 ) and Tyva Republic. Such a habitat preference leads to an idea that sand may be used by E. tripunctatus for nest construction. A nest of this species, found for the first time, however, was made of usual clayey soil without any evidences of the sand use (Fig. 26 ). The nest, found attached to a Crambe maritima L. twig on 28.VII.2020 in the Crimea, was open but abandoned by the mother wasp; there was a fifth-instar larva inside. The next day it began spinning a cocoon from which the adult wasp emerged in July of the same year, indicating the presence of the second generation.
