Notes on Alysdacnusa View in CoL and Tobiasnusa (by CvA).
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 View FIGURES 122–133 ) 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 View FIGURES 111–121 ) vs malar space short, with small convex area above base of mandible in Alysdacnusa ( Fig. 123 View FIGURES 122–133 ); upper lobe of mandible small ( Fig. 119 View FIGURES 111–121 ) vs upper lobe of mandible large ( Fig. 128 View FIGURES 122–133 ); temple mediumsized ( Fig. 112 View FIGURES 111–121 ) vs temple enlarged ( Fig. 126 View FIGURES 122–133 ) in dorsal view; marginal cell of fore wing very narrow ( Fig. 111 View FIGURES 111–121 ) vs comparatively large ( Fig. 122 View FIGURES 122–133 ) and second and third metasomal tergites indistinctly sculptured ( Fig. 121 View FIGURES 111–121 ) vs smooth ( Fig. 131 View FIGURES 122–133 ).
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).
