Abstract: Description of the new species: Microchelonus deplanus from Canada (Ontario) comparing it to its nearest species Microchelonus carinatus (Provancher). Supplement to the taxonomic distinction of the two Nearctic species: Microchelonus fulgidus (McComb) and M. shenefelti (McComb) is presented. 113 Nearctic and 488 Palaearctic species of the genus Microchelonus are registered in cumulative checklists. The total number of the Microchelonus species in the Holarctic region is 601. With 25 line-drawn figures. Keywords: Microchelonus, new species, Palearctic and Neartic Regions, checklist Introduction The first (and so far the last) comprehensive monograph of the Nearctic species of the genus Microchelonus Szépligeti, 1908 has been compiled by Ch. W. McComb in 1968. One hundred eleven (111) species are treated in it of which 90 were described as new to science. Since 1968 no new species was reported as well as no further contribution was published concerning the North American Microchelonus species. Shenefelt (1973: 873-907) was the first giving generic rank to the taxon Microchelonus Szépligeti, 1908. One new species: Microchelonus deplanus is described completed it with the comparison to its nearest ally: Microchelonus carinatus (Provancher). The complementary distinction of the two Nearctic species: M. fulgidus (McComb) and M. shenefelti (McComb) is presented; the two species are very near to each other consequently their specific separation is considerably amplified with new differentation features fitting in an identification key. To promote the future survey of the Holarctic species of the genus Microchelonus the cumulative checklists of the Nearctic and Palaearctic Regions were separately compiled. In the checklists the following taxonomic data are given: original taxon name, describ- er’s name, year of description, (in bracket the original generic name), distribution down to countries (in bracket state, territory, district, area). The synonymous names are inserted in two places: according to the alphabetic affiliation between brackets in the checklist and, on the other, under the valid taxon name after an equals sign (=).
