Didn't realised there is a new posting.
The great difficulty is separating J. elpis & alecto.
This is a female so the upperside spots seen are no use for ID.
In J. alecto the pairs of white striae on the lower part of the forewing in space 1b & 2 are equally broad (or roughly so).
In J. elpis the inner pair are noticeably thinner than the outer 2.
Examples of J. alecto & elpis with extended orange had been shot before, but it is more extensive in J. alecto.

PS. If the forewings are lowered, a 2nd ID option is:
In J. alecto, the outer of the pair of cellend striae (2nd pair from base in the middle) is as thick as the marginal striae in space 2 & 3 (above the tail).
In J. elpis the outer stria at the cellend is thinner than the marginal striae in space 2 & 3.
Note ID features not absolute, but useful
