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.
Lyctoxylon
Lyctoxylon is a genus of powderpost beetles in the family Bostrichidae, subfamily Lyctinae. The genus was established by Reitter in 1878. Members are woodboring beetles that infest dry, seasoned hardwoods. Lyctoxylon dentatum, the type species, has been introduced to multiple continents beyond its native Asian range.
Lyctoxylon dentatum
Oriental Powderpost Beetle
Lyctoxylon dentatum is a powderpost beetle in the family Bostrichidae, first described by Francis Polkinghorne Pascoe in 1866. Native to Asia, it has been introduced to multiple continents including Europe, East Africa, North America, and Australia. As a woodboring beetle, it develops within wood and can cause damage to timber products. The species is commonly known as the Oriental Powderpost Beetle.
Lyctus
powderpost beetles, lyctid beetles
Lyctus is a genus of powderpost beetles in the family Bostrichidae. These beetles are wood-boring pests with a cosmopolitan distribution across all continents except Antarctica. The genus includes economically significant species that infest hardwood products.
Lyctus africanus
African powderpost beetle
Lyctus africanus is a wood-boring beetle in the family Bostrichidae, commonly known as the African powderpost beetle. The species is recognized as a significant invasive pest of dry wood, causing damage by converting wood into powdery frass through larval feeding. It has established populations across multiple continents including its native Africa, Europe, North America, and Southern Asia. Recent detections in Italy represent its expanding range in the Mediterranean region facilitated by climatic conditions.
Lyctus brunneus
brown powderpost beetle, brown lyctus beetle, powder post beetle
Lyctus brunneus is a wood-boring beetle in the family Bostrichidae, subfamily Lyctinae, known as the brown powderpost beetle. It is a xylophagous species that causes significant damage to dry hardwood and bamboo. Originally native to the Neotropical region, it has achieved worldwide distribution through human commerce. The species is notable for its specialized chemosensory mechanism for detecting starch content in wood, which determines oviposition site selection.
Lyctus carbonarius
southern lyctus beetle
Lyctus carbonarius is a wood-boring beetle in the family Bostrichidae, commonly known as the southern lyctus beetle. It is a serious pest of hardwoods, particularly ash, hickory, oak, maple, and mahogany. The species has been introduced to multiple continents through international timber trade and can infest finished wood products in homes, including flooring, furniture, and structural timbers. Infestations often begin before construction of wood articles and can remain undetected until adult emergence holes appear.
Lyctus cavicollis
shiny powderpost beetle, western lyctus beetle
Lyctus cavicollis is a species of powderpost beetle in the family Bostrichidae. Commonly known as the shiny powderpost beetle or western lyctus beetle, it occurs across Australia, Europe and Northern Asia (excluding China), and North America. The species is part of a genus known for infesting and damaging seasoned hardwoods.
Lyctus linearis
European lyctus beetle, powderpost beetle
Lyctus linearis is a wood-boring beetle in the family Bostrichidae, commonly known as the European lyctus beetle or a powderpost beetle. Originally native to tropical regions, it has established populations worldwide through human transport of wood products. It is a significant pest of hardwood timber and finished wood products, causing damage through larval feeding that reduces wood to a fine powder. The species shows particular association with deciduous tree woods.
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.
Minthea rugicollis
hairy powderpost beetle
Minthea rugicollis, commonly known as the hairy powderpost beetle, is a species of wood-boring beetle in the family Bostrichidae. It belongs to the subfamily Lyctinae, a group commonly referred to as powderpost beetles due to their larvae's ability to reduce wood to a fine powder. The species has a broad geographic distribution spanning the Caribbean, Oceania, Southern Asia, and Europe, with additional records from the Galápagos Islands. Like other members of its subfamily, it is likely associated with dry wood products.
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.
Trogoxylon parallelipipedum
Velvety Powderpost Beetle, Velvety Powder-post Beetle
Trogoxylon parallelipipedum is a powderpost beetle in the family Bostrichidae. It is distributed across Australia, Europe and Northern Asia (excluding China), and North America. The species is known by the common name velvety powderpost beetle, reflecting its characteristic appearance. Like other members of the subfamily Lyctinae, it is associated with wood-boring habits.
