Papp, J.: Microchelonus deplanus sp. n. from Canada 119 Microchelonus shenefelti (McComb, 1968): Shenefelt 1973: 903 (comb, n., literature up to 1968). Material examined: 1.) M. fulgidus: one female (in Budapest): Maine, Franklin County, Strong (USA), 9 July 1976, leg. Heinrich, det. J. Papp 2014. 2.) M. shenefelti: two female paratypes (in Washington): Mt. Pleasent, Port Angeles, Wisconsin (USA), 18 July 1945, leg. R. D. Shenefelt, det. McComb. In McComb’s identification key the species M. fulgidus is coupled with M. shenefelti, see key-couplet 62 (in McComb 1968: 10, couplet 62). The two species, very near to each other, are distinguished by three features: size of eye, sculpture of face and scutel- lum. A comparison of the two species the distinctive features between them are modified and completed with further traits: 1 (2) Carapace in dorsal view (Fig. 17) somewhat less broadening, 1.9 times as long as broad posteriorly; in lateral view high (Fig. 18), 2.4 times as long as high behind. Striation of carapace straight and slightly stronger (Fig. 17). Fore wing: 1-R1 shorter, 0.6 times as long as pterostigma, pterostigma itself wide: 2.3 times as long as wide (Fig. 19). Scutellum longitudinally striolate (Fig. 16). Head in dorsal view a bit less transverse: 1.9 times as broad as long, eye 1.8 times as long as temple (Fig. 15). Basal band of carapace straw yellow. $: 3-3.2 mm. - USA: Connecticut, Maine...................................................M. fulgidus (McComb, 1968) 2(1) Carapace in dorsal view (Fig. 20) somewhat more broadening, 1.6 times as long as broad medially; in lateral view less high (Fig. 21), 2.6 times as long as high behind. Striation of carapace slightly less straight and slightly less strong (Fig. 20). Fore wing: 1-R1 nearly, 0.8 times, as long as pterostigma, pterostigma itself less wide: 2.6 times as long as wide (Fig. 22). Scutellum rugulose (Fig. 23). Head in dorsal view a bit more transverse, clearly twice as broad as long, eye 1.9 times longer than temple (Figs 24-25). Basal band of carapace yellow, colour continuing laterally up to middle. §: 3.4—3.6 mm. - USA: Wisconsin ...................................................................................M. shenefelti (McComb, 1968) Remark: In both species eye in lateral view 0.7-0.8 times as high as wide. Also the face of the two species laterally rather aciculate and medially rather subrugulose to rugulose. Consequently the eye measurements in lateral view as well as the facial sculpture do not appear as specific distinctive features (cf. McComb 1968: 10, key-couplet 62). Checklist of the Microchelonus species of the Nearctic Region Besides the fairly well-known Palaearctic species of the genus Microchelonus the Nearctic species are moderately explored. The first species was described by Cresson in 1865 under the name Chelonus laevifrons. Chronologically the following authors have been contributed to the increase of our knowledge concerning the Microchelonus species: Cresson (1865, 1873), Provancher (1881, 1886), Cameron (1887), Ashmead (1889), Viereck (1905, 1911, 1925), Gahan (1917, 1919) and Cushman (1931). The most fruitful specilist was McComb who alone increased the number of the Microchelonus species by describing 91 new species in 1965 and 1968. Besides the Russian V. I. Tobias the American Ch. W. McComb is the second productive in discovering new Microchelonus
