Carpophilus (Myothorax) nepos Murray, 1864

Notes.

This is the first record for Carpophilus (Myothorax) nepos in Canada, obtained from five localities in Ontario in 2018, 2019, and 2020 and four localities in Manitoba in 2019 and 2021. This species, associated with stored grain products, is almost cosmopolitan and its distribution is poorly understood due to its synonym with Carpophilus freemani Dobson, 1956 ( Kirejtshuk 1996). Peck and Thomas (1998) mention that this species has been recorded in the United States and Price (2003) provides records for the state of Wisconsin. Carpophilus (Myothorax) nepos has not been recorded in Canada according to Bousquet et al. (2013).
