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).
Haplidus
Haplidus is a genus of longhorned beetles in the family Cerambycidae, subfamily Cerambycinae, and tribe Hesperophanini. The genus was established by LeConte in 1873 and contains seven described species distributed in North America. Species in this genus are associated with coniferous hosts, particularly pines. Haplidus testaceus, the type species, has been collected from dead Pinus edulis (Colorado pinyon pine) branches, suggesting larval development in dead or dying pine wood.
Trachykele
Trachykele is a genus of jewel beetles (family Buprestidae) containing six described species distributed in North America. The genus belongs to the subtribe Trachykelina within the tribe Buprestini. At least one species, Trachykele blondeli, has been documented developing in red cedar (Thuja plicata) in western North America, with larvae feeding internally in the wood and adults emerging from trees. The genus is part of the diverse metallic woodboring beetle fauna of the Nearctic region.
