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 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.

“…-Pseudosinurus Kirschenhofer, 1999: 74 (type species: P. brunneus Kirschenhofer, 1999);Fedorenko, 2014: 306. DIAGNOSIS. As for the genus [Fedorenko, 2010], except for features of the other subgenera. The subgenus includes macropterous to apterous species, with body more or less slender, dorsum dark unicoloured (except forehead), eyes slightly to strongly flattened, and elytral cross-striated sculpture well-developed in great majority of species included.…”
