Alysdacnusa Tobias & Perepetchayenko, 1995 ( type species: Alysdacnusa breviventris Tobias & Perepetchayenko, 1995 ) and Tobiasnusa Papp, 2004 , ( syn. n. ; their type species differs mainly by having the metasoma shorter ( A. breviventris ) or longer ( A. atomus ) than the mesosoma) are superficially similar to Exodontiella Wharton. The Palaearctic Alysdacnusa has also the marginal cell of the fore wing reduced ( Fig. 122 ) as in the Nearctic Exodontiella and both have exodont mandibles, both occur in semi-arid habitats and share small body size, minute second tooth of mandible and short antenna. However, both genera are not closely related and belong to different subfamilies ( Exondontiella in the Gnamptodontinae and Alysdacnusa in the Alysiinae ). They differ as follows: malar space long, without convex area ( Fig. 113 ) vs malar space short, with small convex area above base of mandible in Alysdacnusa ( Fig. 123 ); upper lobe of mandible small ( Fig. 119 ) vs upper lobe of mandible large ( Fig. 128 ); temple mediumsized ( Fig. 112 ) vs temple enlarged ( Fig. 126 ) in dorsal view; marginal cell of fore wing very narrow ( Fig. 111 ) vs comparatively large ( Fig. 122 ) and second and third metasomal tergites indistinctly sculptured ( Fig. 121 ) vs smooth ( Fig. 131 ). In addition, Alysdacnusa atomus (Papp, 2004) comb. n. from Mongolia ) has vein M+CU of the hind wing about as long as 1-M (longer in A. breviventris ), the propodeum without small tubercle (present), the ovipositor sheath as long as first and second hind tarsal segments combined (0.7 ×), the antenna with 13–14 segments (15–17 segments), vein r of the fore wing issued from middle of pterostigma (slightly before middle) and the first tergite slightly more widened apically (slightly less).
