= Sphingoquedius mannaiaensis (Cameron, 1945), comb. Sphingoquedius novaezeelandiae (Duvivier, 1883), comb. Philonthus umbratilis (Gravenhorst, 1802) = Philonthus insularis (Bernhauer and Schubert, 1916), syn. Philonthus politus (Linnaeus, 1758) = Philonthus ohiaensis (Broun, 1923), syn. The following new combinations and synonymies are proposed: Philonthus longicornis Stephens, 1832 = Philonthus burrowsi (Broun, 1915), comb. Cafioquedus gularis Sharp, 1886 is redescribed. human-transported adventive species (19%) form the notable, most recent and taxonomically heterogeneous component of the New Zealand fauna. species from the Creophilus- and Cafius-complexes (Staphylinina and Philonthina, respectively), are neoendemics (15%), possibly resulting from trans-oceanic colonisation 3. the New Zealand Staphylinini are dominated (66%) by the endemic members of the subtribe Amblyopinina, which are likely Gondwanan paleoendemics 2. With these taxonomic updates, and taking into account the relative age and extant distributions of lineages that occur in New Zealand, we conclude the following: 1. In particular, the hitherto puzzling New Zealand endemic genus Cafioquedus is considered a member of the Creophilus-complex (Staphylinina), while several other endemic species proved to be misidentifications of common introduced species. Here, we bring the systematic knowledge of the New Zealand fauna of the very diverse rove beetle tribe Staphylinini closer to the level appropriate for biogeographic research. The formation of New Zealand's terrestrial biota is a subject where conclusions depend strongly on the properties of the focal organisms. With the updated state of knowledge, the Staphylinini fauna of Lord Howe Island appears to be mainly derived from lineages on mainland Australia. n., and Hesperus dolichoderes (Lea, 1925), comb. n., Ctenandropus mirus (Lea, 1925), comb. n., Cheilocolpus kentiae (Lea, 1925), comb. Taxonomic changes for the tribe are implemented resulting in the following new combinations: Cheilocolpus castaneus (Lea, 1925), comb. Two new species are described: Cheilocolpus olliffi sp. 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. 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. 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. Lord Howe is an oceanic and relatively young island situated in an area of complex geological and therefore biogeographical processes. We propose the following taxonomic changes: synonymy of the subtribes Staphylinina Latreille (valid name) and Eucibdelina Sharp resurrection of genera Barypalpus Cameron and Trapeziderus Motschulsky from synonymy with Rientis Sharp and Belonuchus Nordmann, respectively transfer of 38 Belonuchus species, 16 Hesperus Fauvel species and one Philonthus Stephens species to Trapeziderus as new combinations transfer of two Hesperus species to Eccoptolonthus Bernhauer as new combinations transfer of one Belonuchus species to Paederomimus Sharp as a new combination and transfer of Pridonius Blackwelder new status from its position as a subgenus of Quedius (subtribe Quediina) to Philonthina as a genus, and new combinations for its two described species. Based on our analyses, we propose tentative new concepts of the polyphyletic genera Belonuchus and Philonthus. While the previously hypothesized Neotropical lineage of Philonthina was corroborated, Holisus was recovered as a separate subtribe, outside of Philonthina, within an informal ‘Southern Hemisphere clade’. We found that ‘Staphylinini propria’ is a monophylum consisting of six lineages: current subtribes Anisolinina, Philonthina, Staphylinina and Xanthopygina and two new subtribes, Algonina Schillhammer and Brunke and Philothalpina Chatzimanolis and Brunke. With the aims of resolving the phylogeny of Philonthina and the position and, thus, validity of Hyptiomina, we performed phylogenetic analyses of the tribe Staphylinini based on molecular (six genes, 4471 bp) and morphological (113 characters) data including 138 taxa from all relevant lineages of Staphylinini. A related systematics issue concerns the position of the genus Holisus (Hyptiomina), which was recovered within the Neotropical philonthine lineage in several recent analyses of morphology. With 71 genera and over 2700 described species, Philonthina is the most speciose subtribe of rove beetle tribe Staphylinini and forms a major component of the largest remaining higher systematics challenge in Staphylinini, the ‘Staphylinini propria’ clade.
