Chaetocercus is a genus of hummingbirds in the family Trochilidae.

Taxonomy

The genus Chaetocercus was introduced in 1855 by the English zoologist George Robert Gray with the rufous-shafted woodstar as the type species.^[1]^[2] The name is a combination of the Ancient Greek words khaitē, meaning "hair" and kerkos, meaning "tail".^[3]

The genus contains six species:^[4]

Genus **Chaetocercus** – G.R. Gray, 1855 – six species
Common name	Scientific name and subspecies	Range	Size and ecology	IUCN status and estimated population
White-bellied woodstar Male Female	Chaetocercus mulsant (Bourcier, 1843)	Bolivia, Colombia, Ecuador, and Peru	Size: Habitat: Diet:	LC
Little woodstar Male Female	Chaetocercus bombus Gould, 1871	Colombia, Ecuador and Peru	Size: Habitat: Diet:	NT
Gorgeted woodstar Male Female	Chaetocercus heliodor (Bourcier, 1840) Two subspecies C. h. heliodor C. h. cleavesi	Colombia, Ecuador, and Venezuela	Size: Habitat: Diet:	LC
Santa Marta woodstar Male Female	Chaetocercus astreans (Bangs, 1899)	Colombia	Size: Habitat: Diet:	LC
Esmeraldas woodstar	Chaetocercus berlepschi (Simon, 1889)	Ecuador	Size: Habitat: Diet:	VU
Rufous-shafted woodstar	Chaetocercus jourdanii (Bourcier, 1839) Three subspecies C. j. andinus Phelps, WH & Phelps, WH Jr, 1949 C. j. rosae (Bourcier & Mulsant, 1846) C. j. jourdanii (Bourcier, 1839)	Colombia, Trinidad and Tobago, and Venezuela.	Size: Habitat: Diet:	LC

All these species, except for the rufous-shafted woodstar, were formerly placed in the genus Acestrura.^[5] In 1999 Karl-Ludwig Schuchmann remarked in the Handbook of the Birds of the World that for the species placed in Acestrura: "...no evidence in external morphology justifies treatment in a genus separate from C. jourdanii".^[6]
