This report is the forth one of a series; this Part 1 presents the results of a comprehensive literature screening in search for new bird taxa described in 2008, namely new genera, species and subspecies worldwide. We tracked four new genera, eight new species, 17 subspecies new to science which according to the International Code of Zoological Nomenclature were correctly described. New genera were erected for species or species groups, respectively, of the Rhinocryptidae, Cisticolidae and Parulidae. Six of the new species refer to Passeriformes and two to Non-Passeres, a storm-petrel and a parrot. The distributional areas of the new species often are minute, restricted to remote areas and were hitherto overlooked. In several cases the populations in question were known since long but their remarkable acoustical and genetic properties which led to description of new species were unexplored.In a zoogeographic context most of the new taxa originate from the Neotropics, followed by Palaerctic and Indomalayan Realms. The remainder of taxa are scattered over Australasia, the Afrotropics, and the southern Atlantic islands. In a taxon sequence by genus/species/subspecies there is the following distribution: Neotropis and Caribbean (1/2/8), Palaerctic (-/2/4), Indo-Malaya (-/2/2), Nearctic (2/-/1), Afrotropics (1/1/-), Australasia (-/1/1), and southern Atlantic islands (-/-/1). Replacement names were proposed for two neotropical genera and four subspecies. In Part 2 (to be published in a later issue) a number of splits - namely those of known species into allospecies, which in most cases result in geographic representatives of a superspecies - are also addressed. But we restrict the treatment of these splits to the Palearctic and Indomalayan Realms. We suggest possible flaws in new descriptions and certain splits, regardless 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.
