Abstract
To help resolve phylogenetic and phylogeographic relationships of Southeast Asian birds, we have collected specimens in Borneo, Sumatra, and Java for phylogenetic and morphological study. Here, we compare mitochondrial ND2 gene sequences from some of these new specimens to sequences obtained in previous studies to shed light on genealogical relationships in nine passerine clades: Erythropitta venusta/granatina/ussheri (pittas); Dicrurus hottentottus (drongos); Alophoixus bulbuls; Napothera, Turdinus and Pellorneum babblers; Anthipes flycatchers; Brachypteryx shortwings; and Myophonus whistling thrushes. These comparisons resolve or shed substantial light on taxonomic problems in pittas, Alophoixus, Napothera, Dicrurus, Brachypteryx, and Myophonus, and they confirm assumed (but previously unquantified) genetic relationships within Turdinus and Anthipes. The resulting trees also allow us to (1) suggest improved taxonomic arrangements in several groups, (2) confirm the rediscovery of a "lost" species within Napothera, and (3) provide the basis for the description of a new subspecies of Alophoixus.
