Two new species of the Andean genera Leptopeltus Bernhauer and Leptopeltoides Chani-Posse & Asenjo (Coleoptera: Staphylinidae: Staphylininae) from the tropical Andes, with a new country record and an updated phylogeny.

The tropical Andes are known as a biodiversity hotspot with the highest percentage of endemic plants and vertebrates in the world. The Andean genera Leptopeltus Bernhauer and Leptopeltoides Chani-Posse & Asenjo contain six and four species respectively, most of which occur in the Andean highlands near 3000 m. Here, we describe two new species of the subtribe Philonthina, recently discovered in the northern Peruvian Andes: Leptopeltus dieguezi sp.

First record of the genus Tetradonia Wasmann, 1894 (Coleoptera: Staphylinidae: Aleocharinae) in Colombia, with description of two new species.

This paper describes and illustrates two new species of the genus Tetradonia Wasmann, 1894 (Staphylinidae: Aleocharinae), discovered in the Eastern Andes of Colombia: T. vonbeerensis Gualdrón-Diaz & Chani-Posse sp. n.

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.

Army ant middens - Home and nursery of a diverse beetle fauna.

Army ants provide nourishment to a large variety of animals. This includes birds that feed on animals flushed out by army ant raids, symbiotic arthropods that consume the ants' prey or their brood, and other arthropods that scavenge on army ant refuse deposits. The latter have not received much attention, and the few published studies lack detailed species identifications.

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.

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).

Checklist and taxonomic changes for Central and South American Philonthina (Coleoptera: Staphylinidae).

A checklist of all described species of Philonthina, a subtribe of the staphylinid tribe Staphylinini, known to occur in Central and South America (CASA) is presented. Included for each species, and for synonyms known from CASA, is a reference to the original description, type locality and type depository, and for each species the known distribution within and outside CASA. Type material was sought in the main European and American collections where it is deposited (BMNH, MNHUB, IRSNB and FMNH) and is summarized for all indigenous CASA species, with lectotypes designated for 16 names and confirmation of holotypes and prior designation of lectotypes when necessary.

A catalog of the types of Staphylinidae (Insecta, Coleoptera) deposited in the Museo Argentino de Ciencias Naturales, Buenos Aires (MACN).

The type specimens (all current categories) of Staphylinidae deposited in this Museum are listed; names are recorded, most of them represented by name-bearing types (primary types). The specific and subspecific names are alphabetically ordered in a single list, followed by the generic names (and subgeneric ones, if they were stated) spelled as they were published; later combinations and/ or current binomina are mentioned insofar these are known to the authors. Two lists are added: 2.

An illustrated key to and diagnoses of the species of Staphylinidae (Coleoptera) associated with decaying carcasses in Argentina.

A key to 24 Staphylinidae species associated with decaying carcasses in Argentina is presented, including diagnoses, illustrations, distributional and bionomical data for these species. This article provides a table of all species associated with carcasses, detailing the substrate from which they were collected and geographical distribution by province. All 24 Staphylinidae species recorded are grouped into three subfamilies: Aleocharinae (three species of Aleochara Gravenhorst and one species of Atheta Thomson), Oxytelinae (one species of Anotylus Thomson) and Staphylininae (18 species, two belonging to the tribe Xantholinini and 16 species belonging to the tribe Staphylinini).
