Based on reared material, all the immature stages of Emus hirtus (Linnaeus, 1758) are described. This is an especially interesting species of rove beetle because it looks very striking, hunts dung-inhabiting insects, has a patchy distribution and is a protected species in some countries. Descriptions are supplemented by a few fi eld and laboratory-based observations on adult and larval behaviour and development. Since the phylogeny of the diverse subtribe Staphylinina is poorly known, all available information on the immature stages of the species in this subtribe was summarized and their phylogenetic utility evaluated. Data on Emus and other genera with known immature stages, even though highly fragmentary, reveal a phylogenetic signal in the larval and pupal morphology. They support the Creophilus-Ocypus- and Platydracus-groups as lineages hitherto only based on the morphology of adults and molecular data.

Funding Information:
We are indebted to J. Pedersen, who suggested a good locality in Denmark for Emus hirtus and helped with the fi eldwork. A.K. Hansen is greatly acknowledged for organizing a productive local fi eld excursion to the locality on Samsø within the framework of an AV Jensens Foundation grant on the dung-inhabiting beetles of Denmark and also helped us with this study in other ways. Sincere thanks go to M.F. Christensen for reporting his fi nding of an Emus hirtus larva in NW Jutland and sharing his photographs with us. We are very thankful to C. Li who helped by rearing and collecting larvae of Staphylinina in China, and W.-X. Zhang and C.-L. Zhou who kindly checked the morphological characters of material not available to us. QZ acknowledges that his PhD study on the phylogeny and biogeography of Staphylinina was funded by the Chinese Scholarship Council.
