Abstract (in english)
   We describe a new stem group representative of Pici (woodpeckers, honeyguides, barbets, and allies) from the early Oligocene (Rupelian) of the Czech Republic. The holotype of Picavus litencicensis, gen. et sp. nov. is a postcranial skeleton with well-preserved feather remains. The new species is distinguished from crown group Pici in several plesiomorphic features and is assigned to the new taxon Picavidae, fam. nov. The absence of an elongated accessory trochlea for the reversed fourth toe shows P. litencicensis to be the most basal representative of Pici, and concerning the morphology of the distal tarsometatarsus the species represents a morphological link between Pici and their sister taxon, the Galbulae. Like all other early Oligocene piciform birds, P. litencicensis is a tiny bird, the size of the smallest extant Pici. Because all Palaeogene Pici were found in Europe and some of these are outside the crown group, an Old World origin of Pici is likely. With definitive crown group
   representatives of Pici being unknown before the late Oligocene/ early Miocene, the fossil record does not support earlier molecular calibrations, which resulted in a late Cretaceous divergence of crown group Pici.
