Yes it is J elpis.
The FW blue to the margin can just be seen.
The broken FW postdiscal band indicate the elpis subgroup.

The FW discal striae are thicker in the lower half, so it looks a bit like J. alecto.
A similar example.

Such forms are frequently mis'IDed as J. alecto.

J. caeruleus can also look confusingly similar to J. elpis but the striae are dark-shaded.

TL Seow: Cheers.
