A revision of the Chilean Brachyglutini - Part 4. Revision of Achilia Reitter, 1890: A. puncticeps and A. approximans species groups, with description of seven new species (Coleoptera: Staphylinidae: Pselaphinae)

摘要

The Achilia approximans and A. puncticeps species groups sensu Jeannel (1962) of the species-rich genus Achilia Reitter, 1890 are revised. Achilia puncticeps (Reitter, 1883) is redescribed, and A. approximans (Reitter, 1885) synonymized with it (syn. nov.). Six new species - A. adorabilis n. sp., A. baburra n. sp., A. cunniceps n. sp., A. nipponobythoides n. sp., A. reitteri n. sp., and A. trulla n. sp. - sharing a unique combination of characters with A. puncticeps are described, as well as a seventh new species - A. zaurda n. sp. - whose male was initially confused with that of A. puncticeps. For these species the distribution is detailed, and the habitat/collecting data are summarized.
