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.
