Abstract We investigated the phylogenetic relationships of Campylorhamphus pucherani using DNA sequences from three mitochondrial genes and a nuclear intron, as well as 84 morphological characters from the skeleton, the integument, and the musculature. The molecular phylogeny indicated that C. pucherani is not part of Campylorhamphus; instead, it is the sister species to Drymornis bridgesii, in a clade that also contains Lepidocolaptes. The morphological phylogeny also placed C. pucherani in a clade that contains Drymornis and Lepidocolaptes. Using a morphometric analysis of size and shape diversity, we demonstrated that the inclusion of C. pucherani in Drymornis would create an excessively heterogeneous genus compared with other dendrocolaptine genera. Because no generic name is available for C. pucherani, we describe the new genus Drymotoxeres for this species. Received 18 June 2009, accepted 12 October 2009.
