small-sized Arhopala is rather rare, but reported to be "'taken
with some regularity in Singapore." The species has been encountered
very locally in the nature reserves and makes its appearance relatively
often. On occasions, as many as three individuals are seen in the
same vicinity. The distinct post-discal spot in space 7 separates
this species easily.
The males are a deep purplish
blue above, with a narrow border whilst the females have a broad black
border on the forewings. There are tornal green scales on the hindwings
below, and the species possesses a pair of white-tipped tails.
