It was reported from Prince Edward Island by Majka (2008) . It is widely distributed in the region (Fig. 7). Note: this species has sometimes been referred to as “ Dineutus horni ” a name which Majka (2008) designated as an incorrect subsequent spelling of “ Dineutus hornii .” Morrissette (1979) reported it from boggy and semi-boggy lakes.
