Prostephanus arizonicus
horned powder-post beetle
Prostephanus arizonicus is a species of horned powder-post beetle in the family Bostrichidae, described by Fisher in 1950. It belongs to a genus that includes economically significant stored-product pests, most notably the larger grain borer (Prostephanus truncatus). The species is documented from North America, with the specific epithet suggesting an association with Arizona. Like other members of the genus, it likely exhibits wood-boring habits typical of Bostrichidae, though specific ecological details for this species remain poorly documented.
