It is one of few species in the small genus Flaviellus, which is distinguished from related aphodiine genera by subtle morphological characters.
Homaeotarsus floridanus
A rove beetle (family Staphylinidae) described by LeConte in 1878. The species epithet 'floridanus' indicates a primary association with Florida, though records extend to Maryland and New Jersey. As a member of subfamily Paederinae, it belongs to a diverse group of rove beetles characterized by relatively short elytra and flexible abdomens.
Magdalis alutacea
Wedge-shaped bark weevil
Magdalis alutacea is a species of bark weevil in the family Curculionidae, commonly known as the wedge-shaped bark weevil. It occurs across North America including Canada and the United States. The species was described by John Lawrence LeConte in 1878. It belongs to the genus Magdalis, a group of weevils associated with woody plants.
Odontosphindus denticollis
Odontosphindus denticollis is a species of cryptic slime mold beetle in the family Sphindidae. It is found in North America. The species was described by LeConte in 1878. Records exist from Canadian provinces including Manitoba, New Brunswick, and Nova Scotia.
Orthoperus scutellaris

Pyractomena punctiventris is a firefly species in the family Lampyridae, known from east-central Texas south to Veracruz, Mexico. It belongs to the genus Pyractomena, which comprises bioluminescent beetles commonly found in North American wetlands and riparian habitats. The species was described by John Lawrence LeConte in 1878. Like other fireflies, adults produce light through chemical bioluminescence, though specific flash patterns for this species are not well documented in available sources.
Rhexius substriatus
Rhexius substriatus is a minute rove beetle (Staphylinidae: Pselaphinae) described by LeConte in 1878.

Rhinoscepsis is a genus of minute rove beetles in the subfamily Pselaphinae, established by John Lawrence LeConte in 1878. Members of this genus belong to the tribe Metopiasini within the diverse ant-loving beetle group. The genus name derives from Greek roots suggesting a 'snout-like' or 'nose-bearing' appearance, likely referring to distinctive cephalic structures. As with many Pselaphinae, these beetles are small, cryptic, and poorly documented in public sources.
Stenotothorax sparsus
Stenotothorax sparsus is a small scarab beetle in the subfamily Aphodiinae, first described by LeConte in 1878. The species is documented from limited localities in western North America, including California, Oregon, and Chihuahua, Mexico. Records remain sparse, with only seven observations documented on iNaturalist. As a member of the Aphodiinae, it likely occupies dung-associated habitats, though specific ecological details remain poorly documented.

Tricorynus similis is a small beetle species in the family Ptinidae, first described by LeConte in 1878. It is found in North America, though specific details about its ecology and biology remain limited. The species belongs to a genus of beetles commonly associated with stored products and wood-boring habits, though direct evidence for T. similis is lacking.
