Genus

Protocollyris

23 species

Hidden on the bark of forest trees across tropical Asia, *Protocollyris* is the smallest-bodied genus in the tribe Collyridini, with adults measuring just 5–9 mm yet retaining the group's signature needle-like, highly elongate form. These metallic, fully winged beetles are nocturnal, spending their lives on bark and branches of Oriental forest trees, where their larvae bore tunnels beneath the surface. With roughly 22 species distributed across South and Southeast Asia — from India and Sri Lanka east through the Philippines and Sundaland — *Protocollyris* represents one of the most range-diverse arboreal genera in the family. Its remarkably short, transverse labrum immediately sets it apart from all other Collyridini.

Diagnosis

DIAGNOSIS — *Protocollyris* Mandl, 1975. Body 5–9 mm; smallest-bodied genus in Collyridini. Habitus strongly cylindrical, L:W ratio >3.0. Coloration metallic. Labrum transverse, very short (LL/LW < 0.7) — primary diagnostic character of genus [Acal & Wiesner, 2021]. Eyes medium. Pronotum elongate-cylindrical with distinct basal constriction (Collyridini "neck"). Wings fully developed. Tarsi with adhesive setae on all segments in both sexes (arboreal Collyridina pattern). Activity nocturnal. Habitat: bark and branches of Oriental forest trees; larvae in bark burrows. Distribution: ORI (South Asia, continental Southeast Asia, Sundaland). Type species: *Protocollyris javanica* Mandl, 1975, by original designation.

Etymology

From Greek *prōtós* (first) + Collyris — "first/primitive Collyris".
