Chalcostigma is a genus of South American hummingbirds in the family Trochilidae.

Taxonomy and species list

The genus Chalcostigma was introduced in 1854 by the German naturalist Ludwig Reichenbach.[1] The type species was subsequently designated as the bronze-tailed thornbill by George Gray.[2][3] The name of the genus is derived from the Greek khalkos meaning bronze and stigme for a spot or mark, a reference to the beard on the bronze-tailed thornbill.[4]

The genus contains the following five species:[5]
