118 Natura Somogyiensis anteriorly with faint dark rusty tint. Legs brown, coxae black to blackish. Wings subhyaline, pterostigma and veins light brown. Female and host unknown. Distribution: Canada, Ontario. Taxonomic position: The new species, Microchelonus deplanus, is nearest to M. cari- natus (Provancher) viewing their common features: elongate corporal form, long second submarginal cell of fore wing and black coloured body; the two species are distinct as follows: 1 (2) Carapace in lateral view clearly flattened dorso-ventrally, 5.7 times as long as high posteriorly (Fig. 8). Flead in dorsal view cubic, 1.5 times as broad as long, temple clearly swollen and long: 1.5 times longer than eye (Fig. 1). Fore wing: pterostigma wide, three times as long as wide, 2-SR 2.7 times as long as 3-SR (Fig. 6). Antenna with 22 antennomeres. Apical foramen of carapace narrow, 3.7 times as wide as high medially (Fig. 10). S'- 4 mm. - Canada (Ontario) ........................................................................................................M. deplanus sp. n. 2(1) Carapace in dorsal view less flattened dorso-ventrally, four times as long as high posteriorly (Fig. 11). Head in dorsal view transverse, 1.9-2 times as broad as long, temple faintly swollen and short: as long as eye (Fig. 12). Fore wing: pterostigma less wide, four times as long as wide, 2-SR 1.7 times as long as 3-SR (Fig. 13). Antenna with 24 antennomeres. Apical foramen of carapace three times as wide as high laterally, medially indented (Fig. 14). S'- 5-5.2 mm. - Canada (Onterio, ?Quebec) ...............................................M. carinatus (Provancher, 1881) T axonomic distinction of two known Nearctic Microchelonus species Two Microchelonus species: M. fulgidus (McComb, 1968) and M. shenefelti (McComb, 1968) are very similar to each other hence not clearcut their distinction by the three features given in his key by McComb (1968: 10, couplet 62). Subsequently the two species are separated by features recently recognized. Microchelonus fulgidus (McComb) (Figs 15-19) Chelonus (Microchelonus) fulgidus McComb, 1968: 10 (in key) and 62 (description) $, type locality: ’’Lyme, Connecticus” (USA), female holotype and two female ?paratypes (from ’’Algonquin, Illinois” USA) are deposited in National Museum of Natural History, Washington; type(s) not seen. Microchelonus fulgidus (McComb, 1968): Shenefelt 1973: 887 (comb, n., literature up to 1968). Microchelonus shenefelti (McComb) (Figs 20-25) Chelonus (Microchelonus) shenefelti McComb, 1968: 10 (in key) and 116 (description) 9(5'- type locality: ’’Port Angeles, Wisconsin” (USA), female holotype and three female + one male paratypes are deposited in Department of Entomology, University of Wisconsin, Madison, two female paratypes are in National Museum of Natural History, Washington; the latter two paratypes examined.
