Résumé :

This report presents the results of a literature screening in search for new bird taxa described in 2005, namely new genera, species and subspecies worldwide. We tracked two new genera, seven new species, five subspecies new to science and one new replacement name for a known subspecies. Four Non-Passeres are concerned (2 species/2 subspecies) and nine Passeres (5/ 4). Most taxa originate from South America (6/ 1; among them three species of the speciose genus Scytalopus), followed by tropical Asia (Myanmar, Malaysia: Kalimantan; 1/ 1), the Palearctic region (-/ 2), tropical Africa (Somalia; 4 1) and Oceania (-/ 1). For every new taxon the type locality, number of specimens and depository of the types, reasons for describing the taxon, the taxonomic background, relationships of the new taxon and the characters leading to the discovery and the description of the taxon are noted. The annually increasing number of splits, namely those of known species into allospieces, which in most cases result in geographic representatives of a superspecies, are also addressed. Although our treatment of these splits is restricted to the Palearctic and Indomalayan regions, such splits are very inhomogeneous in reasoning and quality, so that not every split known to us is mentioned here. We took the liberty to hint at flaws of certain splits irrespective of the species concept addressed. However, in general this report should be taken as a documentation of new taxa, not as a critical review of recent changes in bird taxonomy and bird descriptions.
