Pseudochroaptomus ecuadoriensis-a new genus and species of Philonthina and its systematic placement (Coleoptera: Staphylinidae: Staphylininae).

Pseudochroaptomus ecuadoriensis Chani-Posse et al., a new genus and species of the subtribe Philonthina (tribe Staphylinini) from the Tropical Andes of Ecuador, is described and illustrated. A dataset of 35 morphological characters scored for 23 taxa representing main clades of Philonthina, with focus on the Neotropical lineage and its subclades was prepared and analysed by maximum parsimony and Bayesian inference.

Konradus leehermani-a new genus and species of Philonthina from the Neotropical region and its phylogenetic relationships (Coleoptera: Staphylinidae: Staphylininae).

Konradus leehermani Chani-Posse Ramírez-Salamanca, a new genus and species of the subtribe Philonthina (tribe Staphylinini) from the Tropical Andes of Ecuador, is described and illustrated. A dataset of 57 morphological characters scored for 23 taxa representing main clades of Philonthina and its putative sister groups was prepared and analysed by maximum parsimony and Bayesian inference. Both analytical methods unambiguously placed Konradus within the Neotropical (NT) lineage of Philonthina.

To be biased or to be Neotropical: systematic reassessment of a megadiverse lineage of rove-beetles (Philonthina, Staphylinini, Staphylininae).

Classifications in the world's tropics often involve an early and sustained adoption of Holarctic-based patterns. Such is the case of the megadiverse subtribe Philonthina and its Neotropical (NT) members, for which generic limits are ill-defined due to an alleged high level of homoplasy. Although a recent total-evidence study confirmed the monophyly of a NT lineage, most of its species are assigned to the speciose genera Belonuchus Nordmann and Paederomimus Sharp, neither of them monophyletic.

Two new synonyms in Neotropical Philonthina (Coleoptera: Staphylinidae).

As part of an ongoing phylogenetic study on the Neotropical Philonthina (Coleoptera: Staphylinidae) that includes species of Belonuchus Nordmann, 1837, Hesperus Fauvel, 1874 and Paederomimus Sharp, 1885 (Chani Posse Ramírez Salamanca in prep.), we examined type material of species belonging to these genera as well as conspecific material from different European and North American collections. Type and non-type material were either examined by MCP during a visit to the Natural History Museum, London, UK (BMNH) or borrowed from the following institutions: Field Museum of Natural History, Chicago, IL, USA (FMNH), Museum für Naturkunde der Humboldt-Universität, Berlin, Germany (ZMHB), Naturhistorisches Museum Wien, Vienna, Austria (NMW), Canadian National Collection of Insects, Ottawa, Canada (CNC) and Snow Entomological Collection, Natural History Museum/Biodiversity Research Center, University of Kansas, Lawrence, USA (SEMC).
