N. sanaya.
The key indicates that the space between the submarginal & postdiscal spots in HW spaces 4 & 5 should be at least half the width of the postdiscal band.
This will only allow those in which the submarginals & postdiscals are almost touching to be excluded.
The FW submarginal spots have mostly convex margins in subperusia & straight margins in sanaya.
These examples are probably N. sanaya.

This one seem close enough to suggest N. subperusia.
The postdiscal band can not be used to confirm an ID.

Some shots with narrow FW peripheral bands & wide HW spacing suggest. N. pendleburyi
