You are right #1 should be T. menaka.
The postdiscal spot in space 1b is so vague that it disappear when I look downwards.
There is another postdiscal spot to look for.
Above the 4th marginal spot is another small postdiscal spot just besides the large partially hidden postdiscal spot in the upper corner.
This is always present in T. menaka.

This small spot is absent in T. litigiosa.
