This gets way too difficult.
2. I have no idea .
3 is Ypthima lycus.
There is a white fascia which runs roughly from the outer margin of spot 6 to the inside of spot 2.
See. fig 9 & 10 Plate XXXII & pl. XXXIII which shows the upper & undersides .

1 could be Y. watsoni.
The joined ocelli form a closed loop like a racing track, probably giving it its vernacular name.
However the typical Y watsoni looks a bit different.

Y. watsoni from peninsular Thailand.

Thank you for the insight sir...the first two images are of the same individual (one with open wing)...
Yes I should have seen the number.Quote:

Y. watsoni ;UnF discal fascia forms a loop under the the ocellus thus not visible at rest; wsf with very large ocelli ;striations coarse.
Y. asterope; ocelli in wsf small ;striation fine ;UnF also have a loop.
Y. inica; UnF no loop; no prominent submarginal fascia; UnH apical & tornal ocelli not in line .ocellus 2 sifted out.
Y.lycus; UnH apical & tornal ocelli in line. striation obsolete in Y. lycus lycus.
Y. nareda; UnH apical & tornal ocelli in line UnF submarginal fascia prominent; UnH apical ocellus not much bigger than the rest.
Y. newara; UnH ocelli in line; apical ocellus much larger than the rest;striation coarser; UnF submarginal fascia not widening at tornus.
Based on Evans' description some adjustments need to be made.
In Y. watsoni the loop under the FW ocellus can also be seen on the upperside as in the article page 34
The HW ocelli are nearly in line.
http://www.kmnh.jp/wp-content/themes...nastyrskii.pdf
Also Evan states coarse striations & very large ocelli in wsf.
1 meet all the crteria for Y. watsoni ;Loop under FW ocellus; HW ocelli nearly in line; coarse striations; large wsf ocelli.
2.could also be a form of Y. watsoni but it look more like Y. lycus.
The HW ocelli are more or less in line ;the straiton is variable depending on ssp.The whiter diffuse fasciation suggest Y. lycus.
Evans' statement that the HW apical & tornal ocelli are in line for Y. nareda /newara & out of line for Y. inica are rather confusing.
I have pick out examples which suit the description except for the ocelli alignment.
Y. nareda ;FW with submarginal fascia increasing in width at tornus; HW apical ocellus moderately bigger than ocellus 2.

Y. newara;FW submarginal fascia of uniform width; HW apical ocellus much bigger.
https://www.ifoundbutterflies.org/me...ekar_aj717.jpg
Y. inica; FW without submarginal fascia.
