Sternidius wiltii
(Horn, 1880)
Sternidius wiltii is a small longhorned beetle (Cerambycidae: Lamiinae: Acanthocinini) native to western North America. The Sternidius has undergone taxonomic revision, with previously synonymized under S. alpha later revalidated. Specimens are typically collected by beating branches of woody vegetation. The species is small enough to require pointing rather than direct pinning for proper curation.

Taxonomic history
The Sternidius experienced significant taxonomic changes when Chemsak synonymized multiple under S. alpha; these synonymies were later reversed and species including S. wiltii were revalidated. This history illustrates the importance of preserving historical identification labels in collections.
Specimen curation
Due to its small size, S. wiltii is typically mounted on points rather than pinned directly. This places it in the same size category as other small cerambycids such as Euderces and Lampropterus.
