I know you mentioned that C&P4 is sometimes an irritation to refer to, but it's the best reference that we have. As I am outstation now, you may want to check the ID key for the Nacaduba in C&P4. Take a look at the checklist's 4 species, as well as the following, which I currently have only about 50% confidence of the ID of the specimens.

  • Nacaduba pactolus odon
  • Nacaduba subperusia lysa
  • Nacaduba kurava nemana
  • Nacaduba augusta kerriana
Oh, I missed out the N. pavana singapura and N. calauria malayica from the checklist. In these two species, the stripes/bands are very straight and ``bolder'' and lacking the yellow hue (using photos shown in ButterflyCircle checklist).

As for the other 4 species given by you, using plate 37 of C&P4, I can rule out N. pactolus odon, N. subperusia lysa and N. augusta kerriana as they lack the basal pair of lines in the forewing.

Two possible IDs remain: N. beroe neon and N. kurava nemana.
