Gangara lebadea, commonly known as the banded redeye, is a species of hesperid butterfly found in Southeast Asia.

Anterior wings bearing a huge and dense pear-shaped sericeous patch of setae glossed with greyish-greenish and extending nearly from the bottom of the angle formed at the base of the organ by the subcostal and submedian veins about to the level of the end of the fourth fifth of the length of the latter vein, with all the setae directed backwards and slightly outwards; with the costal margin purplish; the outer portion beyond the setulose patch bronzy; and the cilia pale luteous.

Posterior wings purple-glossed, with two subparallel raised discal longitudinal lines of modified scales attached to the apparently thickened bases of the first and second median veinlets, and with the cilia pale orange.

Anterior wings below bronzy-brown with a patch of brilliant amethyst purple sparsely irrorated with white scales and extending from the end of the cell nearly to the apex of each organ, and with the basal portion of the wing-membrane behind the median vein and its first branch whitey-brown passing to ashy posteriorly, and with a tuft of brown-tipped yellow setae arranged longitudinally upon and on each side of the basal half of the submedian vein.

Anterior wings suffused with purple on the disc, which bears three semi-transparent yellow lustrous spots of the same size, relative proportions, and shape as in C. [Unkana] attina, Hewitson, with a fourth smaller and elongate yellow opaque spot placed just in front of the submedian vein rather beyond the middle of the organs.
