Abstract
A new species of tyrant-flycatcher {Tolmomyias) is described from the western Amazon basin. The species occurs in the sub-canopy of river-edge and vdrzea forest, and is syntopic with three other members of the genus (T. assimilis, T. polioce- phalusy and T. flaviventris). The plumage of the new species is quite distinctive, but the wing-formula resembles that of T. sulphurescens, and the vocalizations of the new spe- cies are similar to those of some populations of T. sulphurescens as well. Furthermore, the new species appears to be parapatric with T. sulphurescens insignis, with which it may show an unusual pattern of "opposite-bank" replacement in vdrzea and river-edge habitats.
