Margaiostus
Margaiostus is a genus of click beetles (Elateridae) established in 1978. It was long considered restricted to the New World, with species known from North and South America. The genus was first recorded in the Palaearctic region in 2015 with the description of M. sundukovi from the Russian Far East, significantly expanding its known geographic range. The genus belongs to the diverse click beetle family, whose members are characterized by their ability to right themselves using a prosternal process that clicks against the mesosternum.
