Prostephanus apax
horned powder-post beetle
Prostephanus apax is a species of horned powder-post beetle in the family Bostrichidae, first described by Lesne in 1930. It belongs to the same genus as the economically significant larger grain borer (Prostephanus truncatus), but is considerably less studied. The species is native to Central America and North America. Unlike its congener P. truncatus, P. apax has not been documented as a major pest of stored products.
