Introduction. The name of each listed species is followed by up to five sources that report the species as occurring in Michigan. Sources in all upper-case letters refer to specific insect collections: MSU-ARC refers to material held by the Michigan State University Arthropod Research Collection (data provided by G. Parsons). All others refer to collection data extracted from the Symbiota Collections of Arthropods Network (SCAN) database online at https://scan-bugs.org/. See the Methods page for a list of abbreviations and associated collections.

Species names preceded by a single '?' are considered probable (for occurring in Michigan) but uncertain records. Those preceded by '??' are considered possible but unlikely to occur in Michigan. Species that are fully accepted as having valid Michigan records are unmarked. Species reported in the literature that we consider to be erroneous Michigan records are in a separate list following the others.

The three Michigan species in this group belong to the genus Cimberis which all recent revisers place in the tribe Cimberidini, but there is disagreement as to what family and subfamily names apply.  Arnett et al. (2002) and Bouchard (2011) use the family Nemonychidae and subfamily Cimberidinae.  BugGuide, apparently following Leschen and Beutel (2014), have retained the family name Cimberidae.  Bouchard, however, states that Cimberidae Gozis, 1882 was placed on the Official Index of Rejected and Invalid Family-Group Names in Zoology and Cimberididae Gozis, 1882 placed on the Official List of Family-Group Names in Zoology.  We have elected to follow Bouchard (2011) and are using the family Nemonychidae.
