The tribe contains approximately 60 described genera distributed primarily across East Asia, Southeast Asia, and parts of the Oriental region. Members are characterized by morphological traits typical of Lamiinae, with some genera exhibiting distinctive features such as elytral tubercles or modified antennae. The tribe includes economically significant species associated with hardwood trees.
Moneilema
cactus longhorn beetles, cactus beetles
Moneilema is a genus of large, flightless, black longhorn beetles endemic to North American deserts. The genus contains twenty species distributed across the western United States and northern Mexico. Adults and larvae are exclusively associated with cacti in the subfamily Opuntioideae, including prickly pears (Opuntia) and chollas (Cylindropuntia). The beetles are notable for their remarkable mimicry of darkling beetles in the genus Eleodes, including similar appearance and defensive head-standing behavior despite lacking chemical defenses.
Moneilema annulatum
cactus beetle, ambulated cactus beetle
Moneilema annulatum is a flightless cactus beetle in the family Cerambycidae, first described by Thomas Say in 1824. Adults are found almost exclusively on opuntioid cacti (prickly pears and chollas), where they feed on plant tissues and flowers. Larvae tunnel within cactus stems, often causing visible damage in the form of hardened black exudate. The species occurs across western North America from the Great Plains to the Pacific coast.

Oplosia nubila is a longhorn beetle (Cerambycidae) described by John Lawrence LeConte in 1862. It belongs to the subfamily Lamiinae and tribe Acanthoderini. The species is native to North America, with confirmed records from Canadian provinces including Manitoba, Ontario, and Québec. As with other members of its genus, it is a wood-boring beetle whose larvae develop in dead or decaying wood.
Parmenini
Parmenini is a tribe of longhorn beetles within the subfamily Lamiinae of the family Cerambycidae. The tribe contains approximately 80 genera distributed across multiple continents, with representatives in North America, South America, Europe, Asia, and Australasia. Members exhibit considerable morphological diversity, ranging from small to moderately sized beetles with varied body forms and antennal lengths. The tribe was taxonomically treated by Linsley and Chemsak (1984) in their comprehensive monograph of North American Cerambycidae.
Parmenosoma
Parmenosoma is a genus of longhorn beetles in the subfamily Lamiinae, tribe Parmenini. It contains two described species: P. griseum and P. villosa. The genus was established by Schaeffer in 1908.
Parmenosoma griseum
Parmenosoma griseum is a longhorn beetle species described by Schaeffer in 1908. It belongs to the subfamily Lamiinae within the family Cerambycidae. The species is known from the United States and Mexico, with very few documented observations. As a member of the Parmenini tribe, it shares characteristics with other Parmenosoma species, though specific biological details remain poorly documented.
Peritapnia
Peritapnia is a genus of longhorn beetles (Cerambycidae) in the tribe Acanthoderini. The genus was established by Horn in 1894 and contains four described species distributed in western North America. Members are small to medium-sized cerambycids with affinities to other Acanthoderini genera.
Phaea
Phaea is a genus of longhorn beetles (family Cerambycidae, subfamily Lamiinae) established by Newman in 1840. It belongs to the tribe Tetraopini and is characterized by morphological features typical of this group. The genus has been recorded from Colombia based on distribution data.
Phaea canescens
Phaea canescens is a species of longhorn beetle (Cerambycidae) described by John Lawrence LeConte in 1852. It belongs to the subfamily Lamiinae and tribe Tetraopini. The species is known from the United States, though specific details about its biology, host associations, and ecology remain poorly documented in the available literature.
Plectrodera
cottonwood borer
Plectrodera is a monotypic genus of longhorned beetles (family Cerambycidae) containing the single species Plectrodera scalator, commonly known as the cottonwood borer. The species is among the largest and most visually distinctive cerambycids in North America, recognized by its striking black-and-white checkered pattern formed by dense mats of white setae on a glossy black body. Adults are associated with cottonwood (Populus deltoides) and are found across the eastern two-thirds of the United States, particularly in the Great Plains.
Plectrodera scalator
Cottonwood Borer
Plectrodera scalator, commonly known as the Cottonwood Borer, is a large and striking longhorned beetle (Cerambycidae) native to North America. It is the sole species in the genus Plectrodera. Adults are immediately recognizable by their robust body and distinctive checkered pattern of dense white pubescence on a glossy black background. The species is strongly associated with cottonwood (Populus deltoides) and other Populus species, where adults are most frequently encountered. Despite being described as common in the Great Plains, direct observations remain relatively infrequent, possibly due to cryptic behavior against foliage backgrounds.
Plectrura
Plectrura is a genus of longhorn beetles in the subfamily Lamiinae, tribe Parmenini. The genus was established by Mannerheim in 1852 and contains at least two species: Plectrura spinicauda and Plectrura metallica. Members of this genus are classified within the diverse cerambycid fauna of the Holarctic region.
Plectrura spinicauda
Thorn-tailed Longhorn Beetle
Plectrura spinicauda, commonly known as the Thorn-tailed Longhorn Beetle, is a species of longhorn beetle in the family Cerambycidae. It was first described in 1845 (authored as Mannerheim, 1852). The species occurs in northwestern North America, with records from Alaska, British Columbia, and adjacent regions. It is a member of the subfamily Lamiinae and tribe Parmenini.
Pogonocherini
Pogonocherini is a tribe of longhorn beetles (Cerambycidae) within the subfamily Lamiinae. The tribe comprises approximately 18 genera distributed primarily in the Nearctic and Neotropical regions. Members are generally small to medium-sized cerambycids with varied morphological adaptations. The genus Pogonocherus is the type genus and among the most species-rich in the tribe.
Pogonocherus
flat-faced longhorn beetles
Pogonocherus is a genus of flat-faced longhorn beetles in the family Cerambycidae, established by Dejean in 1821. Species in this genus are wood-boring cerambycids associated with coniferous hosts, particularly pines. At least one species, P. perroudi, has been identified as a potential vector of pinewood nematode (Bursaphelenchus xylophilus), the causal agent of pine wilt disease. The genus contains approximately 30 described species distributed across the Northern Hemisphere.
Pogonocherus mixtus
Mixed-spotted Flatface Sawyer
Pogonocherus mixtus is a species of longhorned beetle in the family Cerambycidae, described by Haldeman in 1847. It occurs across northern and western North America, with records from Canada and the United States. Like other members of the genus, it is associated with coniferous hosts, particularly pines. The species is part of the subfamily Lamiinae, commonly known as flat-faced longhorns.
Pogonocherus parvulus
Pogonocherus parvulus is a small longhorned beetle (Cerambycidae: Lamiinae) described by John Lawrence LeConte in 1852. The species occurs across northern North America, with records from multiple Canadian provinces and the United States. Like other members of the genus Pogonocherus, it is associated with coniferous hosts, though specific biological details remain poorly documented in the literature.
