Nacaduba kurava, the transparent six-line blue,[1][2] is a species of butterfly in the family Lycaenidae found in Asia and Australia.

[1][2] Male upperside: pale dull violet with in certain lights a frosted silvery sheen; bases of wings suffused slightly with blue.

Hindwing: crossed by six or seven irregular, more or less broken, sublunular, white striations; terminal markings similar to those on the forewing; interspace 1 with a minute, interspace 2 with a much larger round jet-black spot, both spots crowned inwardly with ochraceous orange and touched outwardly with glittering metallic blue scales.

Underside: similar to that of the male but the ground colour grey with a slight tint of brown, the transverse white strigae much broader, somewhat diffuse; on the forewing the band formed by the medial pair of strigae much more broken than in the male the posterior portion below vein 3 shifted well outwards; on the hindwing the sub-terminal black spot in interspace 2 comparatively very large and prominent.

There is an interrupted dark hand along the middle of the hack and also spots of blackish on the abdominal segments and just beyond the wing-covers and the sides of the thorax.
