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.

Dienerella filum (Aubé, 1850): Majka et al. (2009); some sources put this in the genus Microgramme, but Dienerella is the currently accepted genus

Enicmus tenuicornis (LeConte, 1878): Majka et al. (2009), LeConte (1878), Fall (1899), Hubbard and Schwarz (1878), Downie and Arnett (1996); most sources do not place LeConte in (), but the original description was in Lathridius

Latridius consimilis (Mannerheim, 1844): Husband and Brown (1976), Andrews (1916), Fall (1899), Downie and Arnett (1996), MSU-ARC; some sources put this in the genus Microgramme

Stephostethus breviclavis (Fall, 1899): Majka et al. (2009), Fall (1899), Leng (1920), Downie and Arnett (1996); the original description was breviclavus, why is it now breviclavis?

Stephostethus liratus (LeConte, 1863): Haack and Ruesink (2020), Fall (1899), Hubbard and Schwarz (1878), MSU-ARC

The following species were also reported from Michigan, but we consider them to be adventive, misidentifications or other errors:

Subfamily Latridiinae

Dienerella elegans (Aubé, 1850): Hubbard and Schwarz (1878), Leng (1920) as Lathridius cordicollis Mannh.; a European sp., does not occur in MI

Latridius fulvipennis Mannerheim, 1853: Andrews (1923) as Coninomus fulvipennis Mann.; this is probably not a valid sp. name
