Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

The One-toothed silvan flat bark beetle faces severe population declines primarily due to the loss and degradation of old-growth forest habitats across its range. Commercial logging operations and forest conversion for agriculture have eliminated many of the mature trees and decaying wood substrates essential for the species' survival. Climate change compounds these pressures by altering forest composition and accelerating the decomposition rates of dead wood, reducing the availability of suitable breeding sites.

Threat summary

Habitat

This beetle inhabits mature deciduous and mixed forests, particularly favoring areas with abundant dead and decaying hardwood trees. The species requires specific microhabitats within rotting logs and bark crevices where it feeds on fungi and organic matter.
