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.
TETRATOMIDAE
5 subfamilies, 2 tribes, 8 genera, 13 species
Subfamily Eustrophinae
Tribe Eustrophini
Eustrophopsis bicolor (Fabricius, 1798): Pollock (2012), Townsend (1886), Hatch (1924), Hubbard and Schwarz (1878), MSU-ARC
Eustrophopsis confinis (LeConte, 1866): Pollock (2012), Andrews (1923), Hubbard and Schwarz (1878), MSU-ARC
Eustrophus tomentosus Say, 1826: Pollock (2012), Leng (1920), Hubbard and Schwarz (1878), Downie and Arnett (1996), MSU-ARC
Synstrophus repandus (Horn, 1888): Pollock (2012), Hatch (1924), MSU-ARC
Tribe Holostrophini
Holostrophus bifasciatus (Say, 1824): Pollock (2012), Hubbard and Schwarz (1878), MSU-ARC
Subfamily Hallomeninae
??Hallomenus debilis LeConte, 1866: Andrews (1923), Hubbard and Schwarz (1878); Andrews specimens in MSU collection IDed by him as this sp. are actually Anaspis rufa
Hallomenus scapularis Melsheimer, 1846: Andrews (1923), Hatch (1924), Hubbard and Schwarz (1878), Ruesink and Parsons (2024), MSU-ARC
Hallomenus serricornis LeConte, 1877: LeConte (1878), Leng (1920), Hubbard and Schwarz (1878), Downie and Arnett (1996), MSU-ARC; described from Marquette material
Subfamily Penthinae
Penthe obliquata (Fabricius, 1801): Andrews (1923), Townsend (1886), Hatch (1924), Hubbard and Schwarz (1878), Ruesink and Parsons (2024), MSU-ARC
Penthe pimelia (Fabricius, 1801): Andrews (1929), Hubbard and Schwarz (1878), Ruesink and Parsons (2024), MSU-ARC
Subfamily Piseninae
Pisenus humeralis (Kirby, 1837): Andrews (1916), Hubbard and Schwarz (1878), Ruesink and Parsons (2024), MSU-ARC
Subfamily Tetratominae
Tetratoma tessellata Melsheimer, 1844: Hubbard and Schwarz (1878), Ruesink and Parsons (2024), MSU-ARC
Tetratoma truncorum LeConte, 1866: Townsend (1886), Townsend (1889), Ruesink and Parsons (2024), MSU-ARC
The following species was also reported from Michigan, but we consider it to be adventive, a misidentification or other error:
Subfamily Hallomeninae
Hallomenus obscurus LeConte: Hubbard and Schwarz (1878); no such species name, apparently intended to write serricornis
