  • Dysmerus

    Dysmerus is a genus of small beetles in the family Laemophloeidae, comprising 15 species distributed across the New World from the southeastern United States to Bolivia and the West Indies. The genus remained monotypic for over a century until a 2025 revision resurrected two synonymized species and described 12 new species. Males possess a grotesquely modified antennal scape of unknown function, a diagnostic feature of the genus. These beetles are rarely encountered, though adults occasionally come to light at night.
