Systematic and biogeographic review of the Staphylinini rove beetles of Lord Howe Island with description of new species and taxonomic changes (Coleoptera, Staphylinidae).
Lord Howe is an oceanic and relatively young island situated in an area of complex geological and therefore biogeographical processes. The island boasts a large number of endemic species, including many beetles, however, few groups are in an adequate state of systematic knowledge for biogeographic investigation. Recent advances in the systematics of the hyper-diverse rove beetle tribe Staphylinini on a global scale enable us to implement taxonomic changes for species from Lord Howe Island. With the improved systematics we are able to make more accurate biogeographic conclusions and set a framework for further more in-depth exploration of this unique island using rove beetles. Two new species are described:Cheilocolpus olliffisp. n.andQuediopsis howensissp. n.Taxonomic changes for the tribe are implemented resulting in the following new combinations:Cheilocolpus castaneus(Lea, 1925),comb. n.,Cheilocolpus kentiae(Lea, 1925),comb. n.,Ctenandropus mirus(Lea, 1925),comb. n., andHesperus dolichoderes(Lea, 1925),comb. n.With the updated state of knowledge, the Staphylinini fauna of Lord Howe Island appears to be mainly derived from lineages on mainland Australia.
