Carpophilus (Megacarpolus) sayi Parsons, 1943

Notes.

Here, we report Carpophilus (Megacarpolus) sayi for the first time in Ontario from 12 localities in 2018, 2019, 2020, and 2021. The species is found throughout central Canada excluding Ontario ( Bousquet et al. 2013) and along the northern United States bordering Canada ( Downie and Arnett 1996). These records suggest that this species could be found throughout Ontario. BugGuide does not specifically exclude Ontario from its distribution; however, Downie and Arnett (1996) include Ontario in their distribution description. iNaturalist does include one locality of C. (M.) sayi near Kitchener, Ontario ( Jakubowski 2021) with a photo attached. The photo submitted to IN could be Carpophilus (Megacarpolus) sayi or C. (M.) lugubris . The two species sometimes look similar enough that Parsons (1943) suggested they could hybridize. According to Parsons (1943) the males of C. (M.) lugubris have two, deep, circular depressions on the hypopygidium and females have a pygidium that is blunt carinate, shining, and tuberculiform at the apex. In contrast, the males of C. (M.) sayi have two, large, vague, shallow depression on the hind margin of their hypopygidium and females have a distinct, blunt carina on the pygidium ( Parsons 1943). Price (2003) also points out that C. (M.) sayi has rectangular humeral angles while the elytral humerals of C. (M.) lugubris are rounded or obtuse.
