Genera and Subgenera of
Longhorn Beetles
Cerambycidae of the Western Palaearctic
A systematic treasury of wood-boring beetles
The Cerambycidae — longhorn beetles — represent one of the most species-rich and ecologically significant families of wood-boring Coleoptera on Earth. Recognised by their characteristically elongated antennae, often exceeding the body in length, these beetles shape forest ecosystems as decomposers, pest species, and indicators of old-growth woodland health.
Comprehensive genus matrix
Each of the 295 genera and subgenera is characterised across 217 variables — from body morphology and larval biology to host plant associations, geographic range, and conservation status. Data sourced primarily from Danilevsky (2020) and Sama (2002), with 198 cited references.
14,647 data cells filled
Host plant coverage
Host plant data are documented for 92 genera, spanning 702 records. From strict monophages feeding on a single host genus to highly polyphagous species attacking over 100 tree families — the database captures the full trophic range of Western Palaearctic Cerambycidae.
702 host-plant records
Conservation & applied data
Six genera are flagged as invasive, including the notorious Anoplophora (Asian Longhorn Beetle) and Phoracantha (Eucalyptus Longhorn). EPPO quarantine status, EU Habitats Directive listings, IUCN assessments, and forest-damage classifications are integrated throughout.
6 invasive genera · EPPO A1/A2
Subgenus architecture
93 subgenera across 36 genera are resolved with individual diagnoses, type species, species counts, and distribution notes — following the authoritative Danilevsky (2020) catalogue and the online update of February 2026.
93 subgenera documented
Eleven subfamilies, one family
The Western Palaearctic Cerambycidae encompass remarkable ecological and morphological diversity, from the massive sawyer-like Prioninae to the wasp-mimicking Necydalinae.

A cross-section of the database — from quarantine pests and forest guardians to obscure Anatolian endemics and ancient laurel-forest relicts.
Data quality & provenance
The matrix operates a three-tier citation system: T1 (★★★) primary taxonomic literature, T2 (★★☆) standard reference works, T3 (★☆☆) frontier or provisional data. Every genus entry carries a JSON citation block (CELL_CITATIONS) linking each character state to its source. All 295 genera hold complete morphological, ecological, and biogeographic confidence scores.

Identification & confusion genera
Each genus entry includes a diagnostic English description, common English and Czech names, confusion genera, key observable field characters, and observation tips for the amateur naturalist and professional entomologist alike.
“A structured identification framework of 7 dichotomous keys (K01–K07), 29 decision-tree nodes, and 20 observer-accessible field markers — enabling reliable determination from living beetles, photographs, and dry collections.”
