It belongs to the tribe Elaphidiini, a group of cerambycids commonly known as flat-faced longhorns. The species is known from North and Central America, with records from the United States, Mexico, and Honduras.

Anelaphus moestus is a longhorn beetle (Cerambycidae) described by John Lawrence LeConte in 1854. The species occurs in North America and Mexico. It belongs to the tribe Elaphidiini, a group of cerambycids commonly associated with woody plants. Specific details about its biology and ecology remain poorly documented in published literature.
Archophileurus cribrosus
Archophileurus cribrosus is a species of rhinoceros beetle in the family Scarabaeidae, subfamily Dynastinae. It is native to the southwestern United States and northern Mexico. The species belongs to the tribe Phileurini, a group characterized by distinctive morphological features. It has been documented across multiple states and Mexican states, primarily in arid and semi-arid regions.
Charaphloeus adustus
lined flat bark beetle
Charaphloeus adustus is a species of lined flat bark beetle in the family Laemophloeidae, described by LeConte in 1854. The species is known from North America with confirmed records in the Canadian provinces of Manitoba, Ontario, and Québec. Like other members of Laemophloeidae, it is associated with bark habitats. The genus Charaphloeus contains multiple species that are morphologically similar and require careful examination for identification.
Cryptorhopalum triste
Cryptorhopalum triste is a carpet beetle species in the family Dermestidae. It occurs in North America, with confirmed records from the United States and Canada. The species is polyphagous, feeding on plants from over 16 families. Larval and pupal stages have been described and reared in laboratory settings.
Ellychnia facula
Ellychnia facula is a species of firefly in the family Lampyridae. It is currently treated as a synonym of Photinus faculus in some taxonomic databases, though the original combination under Ellychnia persists in literature. The species was described by John Lawrence LeConte in 1854 and is recorded as widespread across North America. Like other members of the genus Ellychnia, this species belongs to the 'dark firefly' group—adults that lack the light-producing organs typical of most fireflies.
Eunota praetextata praetextata
Riparian Tiger Beetle
A subspecies of tiger beetle in the family Carabidae, known from the southwestern United States. This subspecies is part of a complex of saline-adapted tiger beetles in the genus Eunota. The specific epithet 'praetextata' refers to a bordered or fringed appearance, likely describing elytral patterning. The nominate subspecies is distinguished from other subspecies of E. praetextata by its distribution and presumably by subtle morphological differences in elytral maculation.
Limnichoderus ovatus
Limnichoderus ovatus is a species of minute marsh-loving beetle in the family Limnichidae. It is associated with marsh habitats in the southern United States and Mexico. The species was described by LeConte in 1854 and belongs to a family commonly known as 'minute marsh-loving beetles' for their affinity for wetland environments.
Mannophorus laetus
Pleasant Aster Bycid
Mannophorus laetus is a species of longhorned beetle in the family Cerambycidae, described by John Lawrence LeConte in 1854. It belongs to the tribe Trachyderini, a group known for often bright coloration and association with flowers. The species is found in North America, particularly the southwestern United States and Mexico. Adults are frequently observed on flowers of Asteraceae, where they feed on pollen and nectar.
Micrixys
Micrixys is a genus of ground beetles in the family Carabidae, subfamily Panagaeinae. The genus was described by LeConte in 1854 and contains at least two recognized species: Micrixys distincta from the United States and Micrixys mexicana from Mexico. These beetles belong to the tribe Panagaeini and are part of the diverse North American carabid fauna.
Neochodaeus striatus
Neochodaeus striatus is a species of scarab beetle in the family Ochodaeidae, commonly known as sand-loving scarab beetles. The species was described by LeConte in 1854 and is known from sandy habitats in the southwestern United States. It is one of several species in the genus Neochodaeus, which is restricted to the Nearctic region.
Omorgus tesselatus
Omorgus tesselatus is a species of hide beetle in the family Trogidae, first described by John Lawrence LeConte in 1854. Like other members of this family, it is a scavenger associated with decomposing animal matter. The species occurs in arid and semi-arid regions of western North America and Mexico. Adults have been observed active at night in sandy habitats, where they may be encountered walking on the ground or attracted to ultraviolet light sources.
Oxacis taeniata
Oxacis taeniata is a species of false blister beetle in the family Oedemeridae, first described by LeConte in 1854. The species is distributed across the Caribbean and North America. As a member of Oedemeridae, it shares the family characteristic of producing cantharidin, a defensive compound. Available information on this species remains limited, with only five observations documented on iNaturalist.
Phymatodes aeneus
Phymatodes aeneus is a species of longhorn beetle in the family Cerambycidae. It was described by John Lawrence LeConte in 1854 and is found in North America, including British Columbia and the western United States. The genus Phymatodes is most diverse in western North America, with 26 currently recognized species in the region.
Physemus minutus
minute marsh-loving beetle
Physemus minutus is a minute marsh-loving beetle in the family Limnichidae, first described by John Lawrence LeConte in 1854. This small beetle is known from limited records across Central America and North America. Like other members of the Limnichidae family, it is associated with wetland and marsh habitats. The species is rarely encountered and poorly documented in scientific literature.
Placonotus zimmermanni
Zimmermann's lined flat bark beetle
Placonotus zimmermanni is a species of lined flat bark beetle in the family Laemophloeidae. It is found in North America. The species was originally described as Laemophloeus zimmermanni by LeConte in 1854. As a member of the Laemophloeidae, it belongs to a group of beetles commonly known as lined flat bark beetles, which inhabit spaces under bark and in decaying wood.
Stenomorpha rimata
Stenomorpha rimata is a species of darkling beetle in the family Tenebrionidae, tribe Asidini. The genus Stenomorpha is large and taxonomically complex, historically containing 88 species with limited modern revision until recent work by Fran Keller and colleagues. S. rimata was described by LeConte in 1854. Species in this genus occur in arid and semi-arid regions of western North America and Mexico, with some flightless species restricted to specific mountain ranges.
Synuchus dubius
Synuchus dubius is a ground beetle species in the family Carabidae, described by John Lawrence LeConte in 1854. It belongs to the subfamily Platyninae and tribe Sphodrini. The species is known from the United States and North America. Like other members of the genus Synuchus, it is a ground-dwelling beetle, though specific ecological details remain poorly documented in published literature.
