Popis: M. brevipetiolatus (Thomson) new combination Figures 4; 22–26 Perilitus brevipetiolatus Thomson, 1892, p 1744. Microctonus vittatae Muesebeck, 1936, p 19. Microctonus zimmermanni Loan & Wylie, 1984, p 240. n. syn. Perilitus brevipetiolatus Haeselbarth, 2008, p 1050. Distribution: Holarctic. Specimens examined: Four hundred and fifty-six from 74 collection events; questionable female identifications: three from two collection events. Flight period: Approximately 98% from May through August. Remarks: The type material of M. zimmermanni fall well into the range of the North American material of M. brevipetiolatus for all distinguishing characters mentioned by Wylie & Loan (1984). The M. zimmermanni series averages slightly larger and is usually lighter than M. brevipetiolatus. The present author has not examined any of the European material. Haeselbarth (2008) recognized two biotypes: the European, bisexual brevipetiolatus and the parthenogenetic vittatae which occurs in Europe and North America. However, Wylie & Loan (1984) and Smith (1952) reported the existence, albeit very rare, of males in North America and Loan (1967b) reported males emerging at a ratio of 1:16. Haeselbarth (2008) noted the morphological characters separating them are slight and variable so that many specimens do not fit well into either group. Indeed, they occur sympatrically and attack the same hosts.
