Coleoptera Australia nomenclature taxonomy classification rutelines


The endemic Australian ruteline genus Mesystoechus Waterhouse, 1878 (Coleoptera: Scarabaeidae: Rutelinae: Anoplognathini: Schizognathina) is revised and compared with Amblochilus Blanchard, 1851 and Bilobatus Machatschke, 1970. Mesystoechus lithgowae new species is described from inland southeastern Queensland. Diagnostic characters and information on the distribution, natural history, and ecology of the two previously described species (M. ciliatus Waterhouse, 1878 and M. costatus Carne, 1958) and a description of the female of M. costatus are given. A key to males of the genus is proposed. Lectotypes are designated for Amblochilus bicolor Blanchard, 1851, Mesystoechus ciliatus Waterhouse, 1878, Homotropus luridipennis Waterhouse, 1878 (now Bilobatus luridipennis), and Homotropus testaceipennis Ohaus, 1901 (now Bilobatus testaceipennis), and their distributions are clarified.
