Anomoea nitidicollis nitidicollis
Anomoea nitidicollis nitidicollis is a subspecies of leaf beetle in the family Chrysomelidae, tribe Clytrini. Members of this genus are associated with host plants in the family Asteraceae. The nominate subspecies occurs in North and Middle America. As with other clytrine beetles, adults are likely flower visitors and larvae develop in association with plant material.
Coleothorpa axillaris quadratominor
Coleothorpa axillaris quadratominor is a subspecies of case-bearing leaf beetle in the family Chrysomelidae. It was described by Moldenke in 1970. The species is part of the genus Coleothorpa, which belongs to the tribe Clytrini within the subfamily Cryptocephalinae. Members of this genus construct protective cases from fecal material, a characteristic behavior of the Clytrini. The subspecific epithet 'quadratominor' suggests a diminutive or reduced quadrate (square) feature relative to the nominate subspecies.
Coleothorpa vittigera
case-bearing leaf beetle
Coleothorpa vittigera is a species of case-bearing leaf beetle in the family Chrysomelidae. The species was first described by J.L. LeConte in 1861. Two subspecies are recognized: the nominate form C. v. vittigera and C. v. arizonensis described by Horn in 1892. The species is native to North America.
Diachus subopacus
Diachus subopacus is a small leaf beetle in the family Chrysomelidae, described by Schaeffer in 1906. It belongs to the tribe Clytrini, a group known for their association with grasses and sedges. The species is found in North America and is one of several species in the genus Diachus, which are generally characterized by their compact, somewhat rounded body form and dull coloration.
Griburius larvatus
Griburius larvatus is a case-bearing leaf beetle in the family Chrysomelidae, occurring in North America. Adults measure 4.32–5.6 mm in length. As a member of the Clytrini tribe, it exhibits the characteristic behavior of constructing protective larval cases from fecal material and plant debris.
Griburius rileyi
Bold-spotted Griburius
Griburius rileyi is a recently described species of case-bearing leaf beetle in the family Chrysomelidae, subfamily Cryptocephalinae. The species was described by Sassi in 2023 and is distinguished by bold spotted patterns on its elytra. Like other members of the genus Griburius, adults are associated with oak woodlands and are attracted to ultraviolet light sources. The specific epithet honors Edward Riley, a prominent coleopterist and indefatigable collector of beetles, particularly known for his contributions to cerambycid and chrysomelid taxonomy.
Lexiphanes mexicanus
Mexican case-bearing leaf beetle
Lexiphanes mexicanus is a case-bearing leaf beetle in the family Chrysomelidae, subfamily Cryptocephalinae. The species belongs to the tribe Clytrini, whose larvae construct portable cases from fecal material and plant debris. It occurs in both Central America and North America. As a member of the genus Lexiphanes, it exhibits the characteristic cryptocephaline morphology with a compact body form adapted for leaf-feeding.
Megalostomis
Megalostomis is a genus of case-bearing leaf beetles in the family Chrysomelidae, subfamily Cryptocephalinae. The genus contains 42 valid species following a 2013 taxonomic revision, with most species distributed in the Americas. Members of this genus are notable for their ant associations and case-bearing larval biology. The genus is divided into seven subgenera, including the arid-adapted subgenus Scaphigenia found in South America.
Megalostomis dimidiata
Megalostomis dimidiata is a case-bearing leaf beetle in the family Chrysomelidae, subfamily Cryptocephalinae. The species was described by Lacordaire in 1848 and has undergone extensive taxonomic revision, with seven former subspecies or related species now synonymized under this name. It occurs in Central and North America. As a member of the Clytrini tribe, it likely exhibits the case-bearing larval behavior characteristic of this group, though specific details for this species remain poorly documented in accessible literature.
Megalostomis subfasciata
Megalostomis subfasciata is a case-bearing leaf beetle in the family Chrysomelidae. It was originally described by LeConte in 1868. A 2013 taxonomic revision designated a lectotype for this species and synonymized two previously recognized subspecific forms: M. subfasciata majorubrofasciata and M. subfasciata murina. The species is recorded from North America and Central America.
Promecosoma inflatum
Promecosoma inflatum is a species of leaf beetle in the family Chrysomelidae, subfamily Cryptocephalinae, tribe Clytrini. It was described by Lefèvre in 1877. The species has a limited known distribution spanning the southwestern United States (Arizona) and Mexico. As a member of the Clytrini, it belongs to a group of leaf beetles often associated with specific host plants, though detailed biological information remains sparse in the published literature.
Triachus
case-bearing leaf beetles
Triachus is a small genus of case-bearing leaf beetles in the family Chrysomelidae, established by J.L. LeConte in 1880. The genus contains five described species distributed in North America. Members of this genus are classified within the tribe Clytrini, which is characterized by larvae that construct portable cases from their own fecal material mixed with plant debris. Adults are leaf-feeding beetles.
Triachus cerinus
Triachus cerinus is a case-bearing leaf beetle in the family Chrysomelidae, first described by John Lawrence LeConte in 1880. The species is known to occur in North America and the Caribbean region. As a member of the tribe Clytrini, it likely constructs protective cases from fecal material and plant debris, a characteristic behavior of this group. Information on its biology and ecology remains limited in published literature.
