Prionus geminus
Prionus geminus is a longhorned beetle species in the subfamily Prioninae, described in 2016 from material collected in the Great Plains region of North America. It belongs to the subgenus Homaesthesis, a group of grassland-associated Prionus species whose biology remains poorly documented. The species is part of a genus whose larvae are subterranean root feeders, though specific host associations for P. geminus have not been established.
Prionus integer
Prionus integer is a longhorned beetle (Cerambycidae) in the subgenus Homaesthesis, endemic to the United States and found in shortgrass prairie habitats of the Great Plains. Adults exhibit unusual burrowing behavior, with both sexes creating shallow soil burrows. Males are strongly attracted to prionic acid pheromone lures, and adult activity appears triggered by rainfall events. The species was described by LeConte in 1851 and remains poorly known compared to economically important congeners.
Pseudastylopsis pini
Pseudastylopsis pini is a species of longhorned beetle in the family Cerambycidae, described by Schaeffer in 1905. It belongs to the subfamily Lamiinae and tribe Acanthocinini. The species has been recorded in North and Middle America, with documented presence in Mexico and the United States. Like other members of its genus, it is associated with coniferous hosts.
Purpuricenus axillaris
White Oak Branch Girdler
Purpuricenus axillaris is a large, showy longhorned beetle in the family Cerambycidae, described by Haldeman in 1847. It is one of three eastern North American species in the genus Purpuricenus, distinguished by transverse basal elytral markings that cover the entire basal half of the elytra in yellow to orange coloration. The species is strongly attracted to fermenting bait traps and has been documented in association with hickory (Carya) as its larval host. It was historically confused with the similar but distinct P. paraxillaris, which was described as a new species in 2000.
Purpuricenus dimidiatus

Like other members of the genus Purpuricenus, it is a large, showy beetle that has been documented in North America. The genus is notable for containing species that are attracted to fermenting bait traps, though specific trapping records for P. dimidiatus are not detailed in the available sources.
Purpuricenus linsleyi
Purpuricenus linsleyi is a rare longhorned beetle species in the family Cerambycidae, described by John Chemsak in 1961. The species was originally known only from the holotype and one paratype from Texas, and was later rediscovered in the Texas hill country by Dan Heffern. It belongs to a genus of large, showy beetles with velvety black bodies and vivid red or orange elytral markings. The species can be confused with P. humeralis due to similar elytral patterning, but differs in having the posterior margin of the basal elytral markings more or less transverse rather than distinctly oblique.
Purpuricenus opacus
Purpuricenus opacus is a species of longhorned beetle in the family Cerambycidae, described by Knull in 1937. It is considered a west Texas specialty that has been recently documented from oak in the Lincoln National Forest of Eddy County, New Mexico, expanding its known range beyond Texas. The species is associated with oak woodlands in pinyon/oak/juniper habitats.
Purpuricenus paraxillaris
White Oak Branch Girdler
Purpuricenus paraxillaris is a large, showy longhorned beetle (family Cerambycidae) described by Ted C. MacRae in 2000 from specimens collected in Missouri. It was the first new species discovered by the author using fermenting bait traps. The species closely resembles P. axillaris but is larger and more robust, with reddish rather than pale orange elytral markings, more developed pronotal tubercles with polished apical lines, and distinctly dentate elytral apices. It is attracted to fermenting baits and has been documented across the eastern United States.
