M a t e r i a l. 1 Ơ, 1 ♀, Ternopil Region: Gusiatyn Distr., “ Medobory ” Nature Reserve [49°11'15.34'' N, 26°10''56.89''' E], Gorodnytsia forestry, right riverside of Zbruch River, meadow, 27.05.199 4 ( Tolkanits) (SIZK).

C o m m e n t. Only one species of genus Toxares is recorded in Europe (Yu et al., 2012).

C o m p a r a t i v e n o t e s. T. deltiger (fig. 9) is very similar to species of genus Ephedrus (fig. 5). The main difference is deltoid form of ovipositor sheath: the base is narrow and the apex is wide and trifid (fig. 9, 8). In addition: 1) 2nd submarginal cell of T. deltiger forewing is rather long (fig. 9, 5); 2) mesoscutal fovea (also present in some Ephedrus species) is very distinct (fig. 9, 3); 3) there are crenulated lateral sutures on mesopleurae (fig. 9, 4), that are absent in Ephedrus species; 4) T. deltiger has asterial (not rounded) excision on posterior margin of propodeum (fig. 9, 6).
