Resumen:
The Neotropics, which are home to around 4000 bird species, are the most diverse region of the world regarding avian diversity and are therefore particularly important for the goals of the All Birds Barcoding Initiative (ABBI). In this context, since 2005 the Museo Argentino de Ciencias Naturales (MACN) in Argentina started a collaboration with the Biodiversity Institute of Ontario (BIO) in Canada to produce DNA barcodes from the 1000 Argentine bird species. In 2008, after having obtained DNA barcodes for more than 50% of Argentinean bird species, MACN started a collaboration with the Colección Boliviana de Fauna (CBF) in Bolivia, as a starting point of a joint initiative to barcode the birds of other Neotropical countries. In total, 3182 COI sequences from 716 avian species were obtained so far. The analyses of these data showed at least 30 cases with deep intraspecific genetic divergence in COI, most of which present geographic structure. Nine of these species exhibit maximum intraspecific divergence of 5% or more; being the most striking case Cyclarhis gujanensis, with 11.34% genetic divergence when comparing individuals from Buenos Aires province with other areas of Argentina. Moreover, we have identified in recent analyses five species for which adding individuals from Bolivia to previous data have revealed the presence of intraspecific lineages with deep divergence and a strong geographic structure: Geositta cunicularia, Asthenes modesta, Myrmoburus myotherinus, Catamenia analis and Knipolegus aterrimus. Here we discuss possible causes that could explain these patterns, suggesting the possibility of the existence of cryptic allopatric species
