(Casey, 1912)
Semanotus terminatus is a of longhorned beetle ( Cerambycidae) in the tribe Callidiini. It is native to North America with confirmed records from multiple Canadian provinces including Alberta, British Columbia, Manitoba, New Brunswick, and Nova Scotia. As a member of the Semanotus, it is presumed to be associated with coniferous , though specific biological details for this species remain poorly documented in published literature. The species was described by Casey in 1912.
