Microctonus muesebecki Loan, 1967, p 234 .

Microctonus barri Loan, 1969, p 413 . n. syn.

Distribution: Southern Canada, eastern and central U.S., and Mexico.

Specimens examined: Four hundred and three from 155 collection events; questionable female identifications: 53 from 37 collection events.

Flight period: Approximately 80% (of collection events) from May through August.

Remarks: The intraspecific variation for this species is rather high. Indeed, several specimens have been identified as M. mellinus , M. eleodis , and M. carabivorus by a number of taxonomists.

The type material of M. barri have pronounced carinae in the depression of the ventral mesosoma in contrast to most specimens of M. muesebecki which have an absence or less pronounced carinae in the depression. Similarly, measurements of M. barri are in the range of M. muesebecki but are larger than average.
