Acanthocinini
Acanthocinini is a large tribe of flat-faced longhorn beetles (Cerambycidae: Lamiinae) described by Émile Blanchard in 1845. The tribe exhibits exceptional diversity in tropical regions and includes numerous genera with cryptic, bark-mimicking coloration. Members are characterized by their orthognathous head orientation, where mouthparts are directed downward rather than forward. The tribe contains economically significant wood-boring species and has been subject to extensive taxonomic revision, particularly in North America.
Acanthocinus
Acanthocinus is a genus of longhorn beetles in the subfamily Lamiinae, described by Dejean in 1821. Species in this genus are associated with coniferous trees, particularly pines and spruces, where larvae develop in the phloem beneath bark. Several species exhibit cryptic coloration that provides camouflage against tree bark. The genus includes notable species such as Acanthocinus aedilis, A. nodosus, and A. princeps (the Ponderosa Pine Bark Borer).
Acanthocinus angulosus
Acanthocinus angulosus is a species of longhorn beetle in the subfamily Lamiinae, first described by Thomas Casey in 1913. It is known from North America, though specific details about its biology and ecology remain limited in published literature. The species belongs to a genus of wood-boring beetles whose larvae typically develop beneath bark of coniferous trees.
Acanthocinus leechi
Acanthocinus leechi is a species of longhorn beetle in the subfamily Lamiinae, described by Lawrence S. Dillon in 1956. It belongs to the tribe Acanthocinini, which includes numerous wood-boring beetles associated with coniferous and hardwood trees.
