Smicronyx commixtus
Dietz, 1894
Smicronyx commixtus is a of true in the , first described by in 1894. It is to North America, with records from the Canadian provinces of Alberta, Manitoba, and Saskatchewan. The Smicronyx includes several seed weevil species associated with sunflowers, though specific ecological details for S. commixtus remain poorly documented. Most information about Smicronyx derives from studies of the economically significant species S. fulvus and S. sordidus.
