It is found in Ecuador and Peru. == Taxonomy and systematics == The short-tailed woodstar was originally placed in genus Calothorax but since approximately 1876 has been placed in its current myrmia. It is the only species in its genus and has no subspecies. == Description == The short-tailed woodstar is about 6 cm (2.4 in) long and weighs about 2.3 g (0.081 oz). It and the gorgeted woodstar (Chaetocercus heliodor) are the smallest birds in South America, though the little woodstar (C. bombus) is only slightly longer. It has a very short, slightly decurved, black bill. Both sexes have shining green upperparts. Males have a white stripe from the bill to below the eye. Their gorget is glittering violet and the breast white with dingy flanks. Their very short tail's central feathers are green and the rest blackish.
