Twelve new species of the genus Amphimenes Bates, 1873 are described from Vietnam: Amphimenes maculatus, sp. n., Amphimenes bidoupensis, sp. n., Amphimenes gracilis, sp. n., Amphimenes montanus, sp. n., Amphimenes giganteus, sp. n., Amphimenes medius, sp. n., Amphimenes minutus, sp. n., Amphimenes rufipes, sp. n., Amphimenes reflexicollis, sp. n., Amphimenes planicollis, sp. n., Amphimenes nitidus, sp. n., and Amphimenes kabakovi, sp. n.. Amphimenes rugulipennis Bates, 1892, comb. n., is transferred from the genus Brachichila Chaudoir, 1869 and is redescribed from fresh material. A key to all congeners is provided, these being arranged into five new species-groups. Adults of the rugulipennis- and piceolus-groups show subcortical habits, while those of the medius-, rufipes- and planicollis- groupsare herpetobiotic, resulting in such morphological adaptations as partly reduced eyes, missing wings and adnate elytra.
