Cychramus adustus (Erichson, 1843)

Notes.

This is the first record of Cychramus adustus for Manitoba found in three localities in 2019. The McNamara (1991) checklist of Nitidulidae recorded C. adustus present in Ontario and Quebec. Majka et al. (2008) recorded C. adustus in New Brunswick, and Webster et al. (2022) recorded C. adustus in Prince Edward Island. There are five records for C. adustus on the IN website that are mostly collected in eastern Ontario and near Montreal, Quebec ( Adustus 2023). The BN website references Bousquet et al. (2013) when describing the range of C. adustus as eastern North America.
