Aphanisticus
metallic wood-boring beetles
Aphanisticus is a large genus of metallic wood-boring beetles in the family Buprestidae, comprising more than 360 described species distributed across every continent except Antarctica. The genus exhibits remarkable cosmopolitan distribution, with species inhabiting diverse environments from tropical to temperate regions. Adults are typically small and often exhibit metallic coloration characteristic of the family.
Clambus
Clambus is a genus of small beetles in the family Clambidae, established by Fischer in 1821. Members of this genus are classified within the superfamily Clamboidea and are part of the beetle group Clambiformia. The genus is poorly known, with limited biological and ecological documentation available in scientific literature.
Crepidodera
Studded Flea Beetles
Crepidodera is a genus of flea beetles in the family Chrysomelidae, comprising approximately 40 described species worldwide. Members are commonly known as Studded Flea Beetles. They belong to the tribe Alticini and possess the enlarged hind femora characteristic of flea beetles, enabling their distinctive jumping behavior. The genus occurs across the Holarctic region, with species documented in North America, Europe, and Asia.
Episernus
Episernus is a genus of small beetles in the family Ptinidae, distributed across the Holarctic region with western populations in North America. The genus comprises approximately 13 described species, primarily associated with coniferous habitats. Episernus is taxonomically close to Ernobius but is distinguished by morphological features of the pronotum and antennae.
Ilopina
Ilopina is a genus of small ground beetles in the family Carabidae. These beetles are part of the diverse Bembidiinae subfamily, which contains many species adapted to riparian and moist habitats. The genus is characterized by its compact body form and association with wet environments.
Notoxus haustrus
Notoxus haustrus is a species of ant-like flower beetle in the family Anthicidae. Members of the genus Notoxus are characterized by their elongated, narrow prothorax that projects forward into a distinct snout-like structure. The genus is diverse in North America, with many species found in arid and semi-arid regions. Like other anthicids, adults are typically found on flowers, foliage, or ground debris where they feed on pollen and small organic particles.
Rhymbomicrus
Rhymbomicrus is a genus of small beetles in the family Anamorphidae, established by Casey in 1916. The genus contains four described species distributed in North America. Members of this genus are part of the diverse cucujiform beetle assemblage, though specific ecological details remain poorly documented.
Sternidius
Sternidius is a genus of flat-faced longhorned beetles (Cerambycidae: Lamiinae: Acanthocinini) established by LeConte in 1873. The genus contains at least 20 described species distributed in North America. Sternidius alpha, a broadly distributed and highly variable species, has been the subject of molecular studies revealing cryptic genetic diversity among color morphs previously treated as subspecies.
Tachyina
Tachyina is a subtribe of small ground beetles (Carabidae: Trechinae: Bembidiini) established by Motschulsky in 1862. Members include diminutive species typically measuring 2–3 mm in body length. The subtribe contains genera such as Tachyura, characterized by distinctive male genitalic morphology and specific puncture patterns on the elytra. Taxonomic revisions continue to clarify species boundaries and the availability of historical infrasubspecific names.
Tachys
Tachys is a genus of ground beetles in the family Carabidae, subfamily Trechinae, tribe Bembidiini. The genus contains at least 270 described species, making it one of the larger genera within the ground beetles. Species have been documented across multiple continents including North America, Europe, Asia, and India. Members are small, fast-running beetles typically associated with moist microhabitats.
