title: New or little-known species of the genus Amphimenes Bates, 1873 (Coleoptera, Carabidae, Lebiinae) from Vietnam.
abstract: Twelve new species of the genus Amphimenes Bates, 1873 are described from Vietnam: Amphimenes maculatussp. n., Amphimenes bidoupensissp. n., Amphimenes gracilissp. n., Amphimenes montanussp. n., Amphimenes giganteussp. n., Amphimenes mediussp. n., Amphimenes minutussp. n., Amphimenes rufipessp. n., Amphimenes reflexicollissp. n., Amphimenes planicollissp. n., Amphimenes nitidussp. n., and Amphimenes kabakovisp. 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.
