We correct the limits of the range and analyse the geographical variation of the Moustached Woodcreeper Xiphocolaptes falcirostris, an endemic species of north-eastern Brazil. A single, undated specimen of Moustached Woodcreeper from Posse, Goiás, in the Paranā River Valley was probably collected somewhere on the left bank of the Sāo Francisco River. Analysis of the plumage variation and five body measurements indicates that it is not always possible to separate the populations of the Moustached Woodcreeper into the two subspecies currently recognized. In spite of this, given the importance of this bird as an indicator species for conservation, we suggest that the current recognition of the subspecies be maintained until genetic studies provide a definitive answer to this taxonomic question. Moustached Woodcreepers are particularly associated with patches of dry forest growing on rich soils, in north-eastern Brazil. In the past decades, this type of vegetation has been drastically modified by human activities. Only an urgent plan to establish a network of reserves for tropical dry forests in north-eastern Brazil can prevent the complete destruction of this habitat and of its poorly known biological resources.
Nós corrigimos os limites da distribuiçāo e analisamos a variaçāo geográfica do Cochi-do-nordeste Xiphocolaptes falcirostris, uma espécie endêmica do Nordeste brasileiro. Um único espécime sem data de X. falcirostris coletado em Posse, Goiás, no vale do rio Paranā, foi provavelmente coletado em algum lugar na margem esquerda do vale do rio Sāo Francisco. Análise da variaçāo da plumagem e de cinco medidas do corpo indicam que nāo é sempre possivel separar as populaçōes de Cochi-do-nordeste em duas subespécies, tal como é feito atualmente. Apesar disso, em consideraçāo à importância desse arapacu como espécie indicadora, nós sugerimos que o Cochi-do-nordeste ainda seja considerado uma espécie com duas subéspecies, até que essa questāo taxonômica seja resolvida definitivamente através de estudos genéticos. Cochis-do-nordeste sâo particularmente associados com manchas de florestas secas crescendo sobre solos ricos no Nordeste brasileiro. Nas ultimas décadas, este tipo de vegetaçāo tem sido drasticamente modificado por atividades humanas. Nós sugerimos que somente um piano urgente visando o estabelecimento de um sistema de reservas para as florestas tropicais secas no nordeste do Brasil possa prevenir a completa destruiçāo desse habitat e de seus pouco conhecidos recursos biológicos.
