Dear Dr. Seow sir, It is been a great experience so far in this valuable forum. Thank you so much for all the guidance and expert opinion. I have to closed the earlier thread because of a technical error. So thought started it as a fresh.

3. Rapala melida nicevillei.

The two forms have been split into two species.

Rapala rhoecus is found in Myanmar Thailand Sumatra & Malaya.
TL Sumatra.
Upperside brilliant blue.
http://yutaka.it-n.jp/lyc4/83940001.html

Rapala melida TL Borneo, formerly considered a ssp of rhoecus.
Taxon nicevillei is found from Assam to Vietnamm.
Upperside is dark indigo blue with a gloss.
The distribution would appear to be disjunct as it is not recorded in Malaya.

7 Ypthima newara.

Elwes & Edwards described the difference between the two. Page 20, & 21.
https://archive.org/stream/transactionsofen1893roya#page/20/mode/1up

On the upperside the submarginal bands widens inwards in Y. nareda in both sexes. It does not in Y. newara.
To this may be added on the HW there is a mid-marginal dark shading that is more pronounced in Y. nareda.
This is also visible on both sides.

Y. nareda Up & Un of each individual.

Wow...never expected this much of information in a single post...a simple thank you will not be enough to acknowledge your efforts...thank you so much sir...
But only one thing, Ypthima nareda is not distributed in North East India. So any other possibility.

I forgot to check out the three rings properly.

11 D Ypthima watsoni. Correction : wrong ID.
Submarginal fascia broaden into a wide marginal band on both side. Fascia absent but a faint line often present.
http://www.samuibutterflies.com/expeditions/satyrinae/ypthimawatsoni/


Ypthima lycus have no submarginal fascia.

Y. asterope. small spots

Y. confusa 'Reduced marginal banding.

Y. fusca ;As in nareda but FW submarginal not expanded; Un submarginal straight; coarse striae; whitish HW mid band.

Wow...this is extraordinary work...i feel proud to be a member of this group...

ID Correction .

11 D is not Ypthima watsoni.
http://www.butterflycircle.com/attachment.php?attachmentid=26395&d=1593081495


Some of the website images of Y. watsoni are in error.

Ypthima watsoni ;
UpF with a prominent fascia inside of the ocellus. This & the submarginal fascia forms a loop round the ocellus.
This is hidden from view.
Submarginal fascia variably heavy.
UnH also with a postdiscal fascia.
HW spot 5 & spot 2 of about equal size.
http://yutaka.it-n.jp/sat/41170001.html

It also does not match Y. confusa well. The ground is more uniform in Y. confusa.
http://yutaka.it-n.jp/sat/41150001.html
https://thaibutterflies.com/project_tag/ypthima-confusa/

There is a strong suggestion this is Ypthima fusca.
Elwes & Edwards description of Y. fusca.
Page 21 last two paragraphs under Y. nareda./
In particular similar to Y. nareda.
Ground whiter with coarser striolations.
Distinct indication of a HW post-median white band.
https://archive.org/stream/transactionsofen1893roya#page/20/mode/1up




TL Seow: Cheers.
PS. Possibly just a Ypthima confusa variant.

10. Choaspes furcatus.

The other three have shorter 'tail'.

13 Choaspes benjaminii.

The differences in Choaspes is very slight.


Choaspes benjaminii
HW black mark in space 1b typically simple, straight, as a rounded spot , may be incurved slightly.
Green hairs cover the upper rim of the eye.

11 D.
Ypthima confusa.

This is a very good match for this from Thailand.
http://www.samuibutterflies.com/expeditions/satyrinae/ypthimawatsoni/

The Ypthima in SE Asia are well researched by Japanese entomologists .
There is no mention of a Y. fusca which is largely unknown.
Thus Y. confusa is the closest & likely correct match.

[Saffron]

Thank you so much Dr. Seow sir...I know it was indeed time consuming and requires a lot of hard work and patience to check and follow literature for several species at the same time...as i already said i am really thankful to you... really appreciate and acknowledge your valuable guidance and suggestions...it is very difficult to id Ypthima with such minute variations...but this discussion will really help me to improve my thoughts and vision on Ypthima especially...

Cheers
:cheers:

[Psyche]

In a way I am glad you brought this up.
I remembered there was a lot of confusion between what is Y. watsoni, confusa & norma (not found in India)in the past.
This was the cause of several mis-IDs on the web.
The Yutaka website on Ypthima ,updated in 2019 has cleared all these uncertainties.

BTW, you will notice 11D is a near identical match for the female Y. confusa from Chiang Mai.
