Tolmomyias is a genus of Neotropical birds in the tyrant flycatcher family Tyrannidae. It is one of the two genera containing the "flatbills"; the other is Rhynchocyclus.

The genus was erected by the Austrian ornithologist Carl Eduard Hellmayr in 1927 with the yellow-olive flatbill (Tolmomyias sulphurescens) as the type species.[1] The genus name Tolmomyias combines the Ancient Greek tolma "courage" or "boldness" with the New Latin myias "flycatcher".[2]

These species are notoriously difficult to identify, except by voice. Their taxonomy is complex and it is likely that some "species" actually include several species level taxa. They are relatively thickset birds with proportionally large heads and, as suggested by their name, flat bills. All have a primarily yellow-green plumage with distinct edging to the wings, and the crown is often grey. They are usually found in humid forests where they forage well above the forest floor and will join mixed flocks. Their bag-shaped nests are often placed near wasp nests.[3]
Species

The genus contains seven species:[4][a]

Yellow-olive flatbill, Tolmomyias sulphurescens
Orange-eyed flatbill, Tolmomyias traylori
Zimmer's flatbill, Tolmomyias assimilis
Yellow-margined flatbill, Tolmomyias flavotectus
Grey-crowned flatbill, Tolmomyias poliocephalus
Ochre-lored flatbill, Tolmomyias flaviventris
Olive-faced flatbill, Tolmomyias viridiceps

Notes

The common names used here are those adopted by Frank Gill and David Donsker in the bird list that they maintain on behalf of the International Ornithological Committee (IOC).[4] Confusingly, the online version of the Handbook of the Birds of the World (HBW) uses different names. In particular, in the IOC list the name "yellow-margined flatbill" is used for the species Tolmomyias flavotectus while in the HBW online list the same common name is used for Tolmomyias assimilis.[4][5]
