Purpuricenus
Purplescent Longhorn Beetles
Purpuricenus is a genus of longhorn beetles (Cerambycidae) comprising approximately 50 species distributed across the Northern Hemisphere. North American species are large, showy beetles with velvety black bodies and vivid red or orange basal elytral markings. The genus has been extensively studied due to its attractiveness to fermenting bait traps, a collecting method that has revealed cryptic species diversity and clarified host associations. The 2000 revision by MacRae resolved taxonomic confusion in eastern North America by distinguishing P. paraxillaris from the similar P. axillaris based on morphological and ecological differences.
Rhagiini
Rhagiini is a tribe of longhorn beetles within the subfamily Lepturinae. Members are characterized by elongated bodies and flower-visiting behavior. The tribe occurs primarily in the Northern Hemisphere with substantial diversity in North America and Eurasia.
Rhamnusiini
Enoploderini
Rhamnusiini is a tribe of longhorn beetles (Cerambycidae) within the subfamily Lepturinae. The tribe was formerly known under the synonym Enoploderini. Members are classified within the diverse lepturine beetle lineage, which contains approximately 150 genera worldwide and is most diverse in the Northern Hemisphere.

Rhodoleptus is a genus of longhorn beetles in the family Cerambycidae, subfamily Cerambycinae, and tribe Trachyderini. The genus was established by Linsley in 1962 and currently contains four described species distributed in North America. Members of this genus are part of the diverse Trachyderina subtribe, which includes many colorful and patterned cerambycine beetles.
Saperda
flat-faced longhorn beetles
Saperda is a genus of flat-faced longhorn beetles in the family Cerambycidae, subfamily Lamiinae, erected by Johan Christian Fabricius in 1775. Species in this genus are wood-boring beetles whose larvae develop in living or stressed trees, particularly poplars, willows, and other broadleaf hosts. Several species are economically significant pests of plantation trees and fruit crops. The genus has a Holarctic distribution with highest diversity in the Palearctic region.
