Sarmydus
Sarmydus
*Sarmydus* [auct., verify] is a robust, flattened Prioninae beetle of 15–30 mm, dark brown in coloration and largely glabrous, encountered across the southern Himalayan arc from Nepal and northern India into southern China. Adults are strongly nocturnal and powerful fliers, drawn readily to UV light during their summer flight window from June to September. Larvae develop deep within the heartwood of broadleaf trees, requiring two to five years to complete development in dead or dying hosts. With eight Palaearctic species and a single representative reaching the European fauna, this genus occupies mid-elevation forest habitats between 500 and 2 500 m.
