Arhopala thamyras

Above light silvery blue, forewing with a blackish margin, but less darkened in the costal area, otherwise quite similar to anthore. The Aru-form exhibits the metallic blue reflection, which in specimens from Amboina is very extensive, in the anal part of the hindwing reduced to 2 small crescentiform spots; this is anthelius Stgr.

[now synonym of A. t. anthore ] is distinguished from Amboina-specimens and from anthore in the male nearly only by its smaller size, whereas the female has a narrower black margin which on the forewing leaves yet free three blue spots behind the cell, whilst on the hindwing it does not extend at all beyond the region at the costal angle.
