Lyctinae
Powderpost beetles, Powder-post beetles
Lyctinae (powderpost beetles) is a subfamily of approximately 70 species of woodboring beetles within the family Bostrichidae. Members are distinguished by their reduced prothorax, which leaves the head more visible than in most woodboring beetles, and by antennal clubs with two segments. The subfamily includes three tribes—Lyctini, Trogoxylini, and Cephalotomini (the latter now synonymized with Trogoxylini)—and occurs worldwide. Some genera exhibit unusual ecological strategies, including the use of galleries created by other beetles rather than excavating their own.
Lyctus opaculus
powder-post beetle
Lyctus opaculus is a powder-post beetle in the family Bostrichidae. It occurs in North America, with records from Canada (Ontario and Québec) and the United States. The species belongs to a genus whose members are known for infesting seasoned hardwoods.
Minthea
tropical powderpost beetles
Minthea is a genus of tropical powderpost beetles in the family Bostrichidae, established by Pascoe in 1863. The genus comprises approximately eight described species distributed in tropical regions. Members of this genus are wood-boring beetles that infest dry wood, contributing to their classification as powderpost beetles alongside related genera in the subfamily Lyctinae.
Trogoxylon
Trogoxylon is a genus of powderpost beetles in the family Bostrichidae, subfamily Lyctinae. These wood-boring beetles are characterized by their association with dry, seasoned wood. The genus includes approximately 15 described species distributed across multiple regions. Trogoxylon impressum has been documented as a pest of fig plants in Turkey, where it causes damage through larval tunneling.
