Sternidius
Sternidius is a genus of flat-faced longhorned beetles (Cerambycidae: Lamiinae: Acanthocinini) established by LeConte in 1873. The genus contains at least 20 described species distributed in North America. Sternidius alpha, a broadly distributed and highly variable species, has been the subject of molecular studies revealing cryptic genetic diversity among color morphs previously treated as subspecies.
