Omoglymmius hamatus

Distinguished from other Omoglymmius species by specific morphological features, though detailed diagnostic characters are not provided in available sources. The small size (6–7 mm) and association with fallen logs in mountainous regions of the Pacific Northwest and California may aid in field recognition.

Adult beetles are 6–7 mm in length. As a member of Rhysodidae, the body is likely dorsoventrally flattened and adapted for living in tight spaces under bark, though specific morphological details for this species are not documented in the provided sources.

Found in fallen logs in mountainous areas. The species occupies decaying wood habitats typical of the family Rhysodidae.

Recorded from Washington, Oregon, Idaho, and California in the United States. GBIF records also indicate presence in Canada.

Inhabits fallen logs, suggesting a fossorial or wood-inhabiting lifestyle consistent with family characteristics.

No documented economic or medical significance. The species is of interest primarily to coleopterists studying the specialized fauna of decaying wood habitats.

• Other Rhysodidae speciesShare the common name 'wrinkled bark beetle' and similar flattened body form adapted for life under bark; precise identification requires examination of specific morphological characters not detailed in available sources.

The common name 'wrinkled bark beetle' can refer to the entire family Rhysodidae, not exclusively to Omoglymmius hamatus.
