Stoparola Blyth, J. A. S. B., xvi, p. 125 (1845). Type, Stoparola melanops*
The genus Stoparola differs from Cyornis in having a shorter, very depressed bill which, viewed from above, forms an equilateral triangle. Both sexes have a certain amount of blue-green almost throughout their plumage but at the same time the sexes vary considerably in colour.
One of the three species found in the Indian Empire has a very widely extended range, the other two are confined to comparatively small areas. S. sordida and S. albicaudata are good species in no way linked with S. melanops.
