Revision of the genus Chiasognathus Stephens of southern South America with the description of a new species (Coleoptera, Lucanidae, Lucaninae, Chiasognathini)
M.J. Paulsen, Andrew Smith
Abstract The genus Chiasognathus Stephens is revised and now consists of seven species, all of which are endemic to southern South America. The genus-level names Bomansodus Chalumeau & Brochier, Carmeniella Molino-Olmedo, and Ramireziella Molino-Olmedo are all confirmed to be synonyms of Chiasognathus. A new species of Chiasognathus is described from the Biobio Region of Chile. The species Chiasognathus mniszechii Thomson is removed from synonymy and is a valid species with Chiasognathus schoenemanni Kriesche as its junior synonym. In order to promote nomenclatural stability, a lectotype is designated for the name Chiasognathus reichei Thomson, and a neotype is designated for the name Chiasognathus pygmaeus Dallas.
