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.

BOSTRICHIDAE

3 subfamilies, 3 tribes, 8 genera, 16 species (plus 4 species reported for Michigan in error)

Subfamily Bostrichinae

Tribe Bostrichini

Amphicerus bicaudatus (Say, 1824): Fisher (1950), Hubbard and Schwarz (1878), MSU-ARC

Lichenophanes armiger (LeConte, 1866): Fisher (1950), Hubbard and Schwarz (1878), Andrews (1916), MSU-ARC

Lichenophanes bicornis (Weber, 1801): Fisher (1950), Andrews (1923), Hatch (1924), MSU-ARC

Lichenophanes mutchleri Belkin, 1940: Fisher (1950), MSU-ARC

Lichenophanes truncaticollis (LeConte, 1866): Fisher (1950), Downie and Arnett (1996), Hubbard and Schwarz (1878), MSU-ARC

Tribe Xyloperthini

Scobicia bidentata (Horn, 1878): Fisher (1950), Downie and Arnett (1996), Hubbard and Schwarz (1878), MSU-ARC

Xylobiops basilaris (Say, 1824): MSU-ARC, BugGuide, Haack (2020)

Subfamily Dinoderinae

Prostephanus punctatus (Say, 1826): Haack and Ruesink (2020), MSU-ARC

Rhyzopertha dominica (Fabricius, 1792): Ruppel (1977), MSU-ARC

Stephanopachys cribratus (LeConte, 1866): Fisher (1950), Downie and Arnett (1996), Hubbard and Schwarz (1878)

??Stephanopachys densus (LeConte, 1866): Downie and Arnett (1996), Hubbard and Schwarz (1878); an east coast & SE sp., MI record doubtful and needs confirmation

Stephanopachys rugosus (Olivier, 1795): Ruesink and Parsons (2021), MSU-ARC

Stephanopachys substriatus (Paykull, 1800): Hubbard and Schwarz (1878), Andrews (1923), MSU-ARC

Subfamily Lyctinae

Tribe Lyctini

Lyctus carbonarius Waltl, 1832: Hubbard and Schwarz (1878), MSU-ARC

Lyctus linearis (Goeze, 1777): MSU-ARC, PSUC:ENTO

Lyctus opaculus LeConte, 1866: Hubbard and Schwarz (1878), MSU-ARC

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

Sinoxylon anale Lesne, 1879: Fisher (1950); a port interception, presumed not established

Heterobostrychus hamatipennis (Lesne, 1895): BugGuide; Detroit July 2012 "in a false ceiling", det. from photo by Robert Beiriger; BugGuide: "native to so. Asia, introduced from India into NC and then FL; established in se. FL"

Dinoderus (Dinoderus ) minutus (Fabricius, 1775): Ruesink and Parsons (2021), MSU-ARC; tropical cosmopolitan - adventive in bamboo, presumed not established

Stephanopachys amplus (Casey, 1898): Borowski (2020); presumably listed in error. This is an Arizona sp. apparently known only from the type (Fisher 1950).
