Hi Dr. Seow, need some clarifications on Pseudocoaldenia.

8. Is the horse-shoe cellspot characteristic of only Pseudocoaldenia dan dan or other sub species of Pseudocoaldenia dan too.
Could the one below be Pseudocoaldenia dan dan?

9. Could this be P. festa or is it P. fatua?

Pseudocoladenia dan dan. Correction: Pseudocoladenia fabia.

Pseudocoladenia fatih.
Correction: Pseudocoladenia fatua.

Both P. dan & fabia have the FW cellspot split into two or joined as a horseshoe.

P. dan spots pale whitish yellow.
Spots separated ie small spot in space 3 welldetached from spot 2 & cellspot.

P. fabia .spots whitish yellow.
Uppersde dark-shaded brown. cellspot notched/horseshoe.
Spots 2, 3 & cellspots close together.

Revision.

9.https://www.butterflycircle.com/atta...chmentid=28658
Pseudocoladenia fatua.

Evans said of fatua of having spots as in fatih, being smaller redder with more produced wings.

He said of the spots in fatih being contiguous but not conjoined. the ground colour a dull tawny brown

Each species is very variable.
Based on this it much more likely to be fatua.
P. fatih is also largely in the western part of the Himalayas,Kangra to Nepal.


tL Seow: Cheers.

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.
https://archive.org/details/catalogu...p?view=theater

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...515_242379.jpg
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.

https://www.ifoundbutterflies.org/si...f8b2bb89-2.jpg
https://www.ifoundbutterflies.org/si...6385db66-1.jpg



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.

https://www.ifoundbutterflies.org/si...118_247698.jpg
https://www.ifoundbutterflies.org/si...7b1a60-1_1.jpg



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.

https://www.ifoundbutterflies.org/si...es/a-28804.jpg
https://www.ifoundbutterflies.org/si...901ba965-1.jpg
Probable P. festa Thailand, with spots conjoined.

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.
