Good evening Dr.Seow Sir...
These two individuals of Ypthima are taken in recent time from Jampui Hill, Tripura., those are looking very interesting....
Please help me in identification with id keys...
1. Ypthima dohertyi or lisandra?
28617
28618
2. Ypthima methora/affectata/similis/persimilis?
28619
28620
28621
Thank you in advance...:)

It goes without saying that Ypthima is extremely difficult.
The internet archives system is inaccessible at the moment, so I am hampered in my search.
Both are five-rings so the search is to eliminate the unlikely.
The unlikelies are.
1. Y. dohertyi.Large, Spots appear small; UnH largely unmarked.

2. Y. lisandra UnF spot always ovate (egg-shape). UnH spots 1b, 2 & 3 nearly in line.

3. Y. atrax. UnH spots in space 1b, 2, & 3in line, tornal spot single, round.

4. Y.baldus Underside heavily fasciated, outer fascia bent/crooked.
https://yutaka.it-n.jp/sat/41000001.html
5. Y. persimilis. UnH tornal spot as one, & not aligned with spots 2 & 3.

6. Y. methora. No info.

Added.
Fig 20-21 .

Possible.
1 looks to be Y. savara.
Y.savara Large. UnH spots conjoined in pairs, spot 6 large, twin fasciae regular, parallel.

2. is possibly Y. affectata. UnF yellow ring thicker.(wsf).

Y. similis is similar, but paler on the upperside. UnF yellow ring thinner (wsf).

Thank you so much sir for these systematic information...
Sir, does Ypthima methora have wavy fasciae on under HW?

The HW fascia is wavy but variable & probably not reliable for diagnostic purpose.
Here is another image which is from Seitz's Macrolepidoptera of the World.

Correction.
2 should be another Ypthima savara.
in Y. savara the UnH twin fasciae are regular & parallel, (most often straight).
UnH spot 6 is large.
https://yutaka.it-n.jp/sat/41070001.html
In Y. affectata & similis (also baldus) the outer UnH fascia is always crooked/undulate.

I guess if an imaginary line links two subapical ocellus, then that line does not touch tornus spots in 2nd individual; but the line touches tornus ocellus in 1st individual. Perhaps this is not an identifying key!
Is it any identification key???

There is much variation but it can be a useful guide.
Fieldshots can be confusing.
This is a rough guide.
Will need revising later on.

Thank you sir...
If we imagine a line through apical spots 4 and 5, then it can touch tornal spots or can't. Is it any meaningful ID keys?

Never thought of that.
You will need to study dozens of set specimens of different species to see if it is useful.
TL seow; Cheers.
