Polylobarthron
Polylobarthron
*Polylobarthron* [auct., verify] is a robust, large-bodied longhorn beetle (15–30 mm) of the subfamily Prioninae, known from Iran and the broader Central Asian steppe zone. Its nocturnal habits and strong flight make it conspicuous at UV light traps, the most reliable method for detection across its arid and semi-arid habitats from lowlands up to 1500 m. Larvae develop over 2–5 years within the deep heartwood of dead or dying steppe shrubs, reflecting a semivoltine life cycle typical of large-bodied Prioninae. As a monotypic genus of restricted range, it carries conservation interest and an IUCN status of Near Threatened.
