Thanks a lot Dr. Seow. Much clearer understanding now and left with only P. dan and P. fatua in my collection . Hope will get the others someday.

Revision 2.

No8.https://www.butterflycircle.com/atta...chmentid=28657
Pseudocoladenia fabia.


The Pseudocoladenia can be thoroughly confusing.
Veri likely many misIDs on the web.

Here is my revision of the genus.
PSEUDOCOL.png

A. FW spot 2 not extending beyond (or before) the origin of vein 3.

A1, Pseudocoladenia dan.
FW spot 3 typically well detached.
Cellspots often two or united as one, as a horseshoe, lower arm much longer.
Southern half of India.

https://www.ifoundbutterflies.org/si...715_242288.jpg

A2. Pseudocoladenia fabia.
FW spots are larger & closer together.
FW cellspor single ,variably notched ,but lower not much longer.
Northern half of India.

B. FW spot 2 extend beyond the origin of vein 3.
All spots larger & close together.

B1. Pseudocoladenia fatih.
Spots in both sexes white or whitish.
Spots are contiguous (touching) but not conjoined (borders merging)
Ground colour dull tawny brown with the dark spots more conspicuous ( more prominent).
Western Himalayas, Kangra to Nepal.

B2 Pseudocoladenia fatua.
Similar to P. fatih but smaller ,bright reddish brown with more produced wings ( ie, sharper/longer).
Probably the FW spots may be conjoined in some example.
Lower foothills.

B3. Pseudocoladenia festa.
Darker, spots larger & becoming cnjoined.
Male wit spots pale yellow, female white.
Higher elevation.

Thanks a lot Dr. Seow for the detailed discussion. The ones I got at lower altitude areas like Guwahati are P fabia while those taken at higher altitude areas like Shillong are P fatua.

Dear Dr. Seow,
Kindly provide the ID keys to differentiate between Porotia erycinoides, P. hewitsoni and P. pleurata. I m sharing two specimen photos which I have.

10.a Taken in Arunachal Pradesh

11. Taken in Meghalaya

ID please.
It seems to have features of both Mimathyma ambica and bhavana (as per my books).

Male Poritia hewitsoni hewitsoni.
The undersides are just too difficult & inconsistent to separate.


P. hewitsoni.
Male UpH cell & space 4 with some blue patches or scalings.
upF cell often black or with a small basal blue & sometimes a mid cell blue spot.
Ssp tavoyana UpH cell & space 4 mostly blue with the cellend vein black.
Female with extensive purple on HW.
Very variable.

P. erycinoides.
Male often a deeper blue.
Male UpF cell with a basal blue bar.
UpH cell & space 4 black except for small blue patch in space 4, nearer margin.
Female UpH mostly brown, with orange mark & little blue.

https://wingscales.com/Lycaenidae/Po...inoides-elsiei

P. pleurata.
UpH cell & space 4 largely black as in P. erycinoides.
Male UpF cell mostly blue/green.
Underside grey ground with cinnamon bands.

Mimathyma ambica.
FW with three subapical spots. Brilliant blue gloss.
FW margin less curved.
https://www.ifoundbutterflies.org/si...c1c851d4fa.jpg
https://wingscales.com/Nymphalidae/M...ambica-miranda


Mimathyma bhavana.
FW with two subapical spots. Less blue? (Moore 's description of the type specimen he have, which have two subapical spots.)
FW margin more incurved;
Submarginal spots mostly absent.
https://www.ifoundbutterflies.org/si...?itok=upazMZqD
Moore's description.
https://archive.org/details/transact...p?view=theater

Verdict; This have the appearance of Mimathyma bhavana.
The sharper FW with more incurved margin, the lack of submarginal spots.
The third tiny subapical spot could easily be a variable feature & absent in most examples of M. bhavana.
The veins on the FW white band are also more distinctly darkened.


TL Seow: Cheers.
PS. Doubleday's description of M. ambica (as Apatura namouna.)
He mentioned of the submarginal spots seven on the posterior wing.
https://archive.org/details/annalsma...p?view=theater
This example of M. ambica have the third tiny subapical spot almost obsolete.

This is best left as a form of M. ambica with reduced markings. Confirmation :It is M. ambica with reduced HW submarginal spots.
There is wide variation in this species but all seem to have three FW (sub)apical spots.

M. ambica.
FW usually with 3 (sub)apical spots.
Usually with a series of white submarginal spots (at leasr HW apex.) .
Hw lacks a defined fulvous brown submarginal fascia (band).
https://www.ifoundbutterflies.org/si...711_265527.jpg
Underside ;FW discal spots less distinct; HW brown band broad.
https://www.ifoundbutterflies.org/si...350_265534.jpg
Form with the UpH submarginal spots reduced.

https://www.ifoundbutterflies.org/si...les/tbe876.jpg

M. bhavana.
Usually two (sub)apical spots.
Submarginal white spots absent.
Fulvous brown submatginal fascia(band) especially on HW.
Underside UnF discal spots whiter, more contrasting; HW brown band narrower.
