In Wisconsin, Microrhagus opacus, Euryptychus ulkei and Fornax bicolor are recorded for the first time. Records for these three species are based on nine specimens, most of which were taken since 2008. Two specimens of M. opacus taken from a Grant County Malaise trap in the late 1970’s as part of a statewide gypsy moth parasitoid recovery project, were previously identified as Microrhagus audax. Most of the specimens reported herein were taken late in the collecting season, primarily during August. A checklist of the 20 genera and 41 species of Wisconsin Eucnemidae is also included.
