Jan Klimaszewski and Christian Maus (1999) Types of species of Aleochara described by Bernhauer from South America are reviewed and assigned to subgenera. Each species is provided with a short diagnosis, drawings of genitalia, photographs of type specimens, and a short discussion on relationships. The following species are considered to be valid: Aleochara (Xenochara) aliipennis (Argentina, Chile), A. (Aleochara) bruchi (Argentina), A. (Xenochara) bruchiana (Argentina), Aleochara (Xenochara) argentina (Brazil), A. (Xenochara) glabra (Argentina), A. (Xenochara) lacustris (Peru), A. (Xenochara) opacula (Brazil), A. (Aleochara) parvicollis (Peru), A. (Xenochara) richteri (Argentina), A. (Xenochara) weiseri (Argentina), and A. (Maseochara) missionis (nom. nov. for Maseochara argentina). Aleochara (Xenochara) wittei (Argentina) is considered here to be a new synonym of A. (Xenochara) richteri. Six new species groups are erected: Bruchi group to accommodate A. bruchi, Glabra group to accommodate A. glabra, Weiseri group to accommodate A. weiseri, Richteri group to accommodate A. richteri and A. bruchiana, and Lacustris group to accommodate A. lacustris and A. aliipennis. Aleochara glabra and A. weiseri are transferred from Coprochara to Xenochara. A. (Maseochara) missionis, nomen novum, is proposed to replace Maseochara argentina. Lectotypes are designated for the following species: A. argentina, A. bruchi, A. bruchiana, A. glabra, A. opacula, A. parvicollis, A. weiseri, and A. wittei.
