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.

A new species of the southern Central American genus Linoderus Sharp (Coleoptera: Staphylinidae: Staphylininae) with a revised key and an updated phylogeny.

Linoderus smetanai sp. nov. is described from Costa Rica.

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.

A new species of the Andean genus Leptopeltus Bernhauer (Coleoptera: Staphylinidae: Staphylininae) with a revised key and an updated phylogeny.

Leptopeltus trogloxenus López-Prada Chani-Posse, a new species of the subtribe Philonthina (tribe Staphylinini) from the Andes of Colombia, is described and illustrated. A dataset of 49 morphological characters scored for 10 taxa, including all currently known species of Leptopeltus Bernhauer and its putative sister group, Leptopeltoides Chani-Posse Asenjo, was prepared and analysed by maximum parsimony. Our analysis unambiguously placed L.

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.
