Description

Male upperside: white. Forewing: apex and termen very broadly brownish black, the inner margin of the black area angulated outwards in the middle of interspace 3, the basal third of the wing suffused with very pale greyish-blue, the costal and dorsal margins up to the black area sullied with pale brownish. Hindwing: the costal area from base to termen in a line above the cell brownish black, the white on the posterior half of the wing more or less stained and sullied with brownish. Underside: white. Forewing: costa and apex mottled with brownish, termen broadly brownish black, cell from base with a broad diffuse fuscous patch that extends below the median vein and outwards on to the disc. Hindwing: densely and more or less uniformly mottled with fuscous brownish-black. Antennae, head, thorax aud abdomen fuscous brown above and beneath.

Female upperside: similar to that of the male, but differs as follows: Forewing: base outwardly to beyond the cell strongly suffused with bluish grey, only the upper apex of the white area with the ground colour distinctly showing through; apex and termen more broadly and more densely black. Hindwing: entirely bluish grey, the costal margin broadly irrorated with dusky scales. Underside: as in the male, but the costa, apex and termen broadly in the forewing, as well as the whole surface of the hindwing, mottled with brownish; the scaling of this colour forms irregular spots and patches especially on the hindwing, which has a blotched appearance compared with the same wing in the male. The basal fuscous cloud extends into the medial white area in the forewing as in the male. Antennae, head, thorax and abdomen similar to those of the male.[3]

Range

This species resides in Manipur, Myanmar and Laos.[1]

gollark: I've heard of that and vaguely looked at using it, but the server stuff still seems very WIP.
gollark: Although Discord has giant servers now, so good luck leaving without missing tons of stuff!
gollark: If you want to move off Facebook you'll probably worry about losing contact with 293848 people you don't have anywhere else, if you want to move off Skype you might just have something like 5 people in a group with you.
gollark: It mostly doesn't happen unless the existing stuff is also very bad. I suspect it's also easier for somewhat purpose-specific instant messaging than for general social network stuff because the group which has to move with you is smaller and you don't have to migrate giant friend lists or something.
gollark: Even if better services *do* exist, people generally don't move to something they don't have stuff/people they know on.
