Stenotrachelidae

Definition

A family of beetles (Coleoptera) in the superfamily Tenebrionoidea, commonly called false longhorn beetles. Members are native to the Northern Hemisphere; larvae develop in heavily decomposed wood, while adults are likely short-lived and probably feed on pollen. The family is distinguished from true longhorn beetles (Cerambycidae) by morphological and phylogenetic characters despite superficial resemblance.

Etymology

From Greek stenos (narrow) + trachelos (neck), referring to the constricted prothorax characteristic of these beetles; family suffix -idae.

Example

The genus Cephaloon, placed in Stenotrachelidae, contains species whose larvae inhabit punky, decayed wood in temperate forests, contrasting with the living or recently dead wood preferences of many cerambycid larvae.

Synonyms

• false longhorn beetles

Related Terms

• Tenebrionoidea
• Coleoptera
• Cerambycidae
• Cephaloon
• larval habitat
• saproxylic

Usage Notes

Distinguished from Cerambycidae (true longhorn beetles) by family-level characters; the common name 'false longhorn beetles' reflects this convergent morphology. Adults are rarely collected and poorly known compared to larvae. The family's placement in Tenebrionoidea rather than Chrysomeloidea (which contains Cerambycidae) is well-supported by molecular and morphological data.
