Thanks a lot Dr. Seow. Sometimes we are so focused on one part of the wings that we totally forget to look at other parts and gets confused.

[Ngangom Aomoa]

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?
DSCN8291.JPG

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

Pseudocoladenia dan dan. Correction: Pseudocoladenia fabia.

9.https://www.butterflycircle.com/atta...chmentid=28658
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.
https://www.ifoundbutterflies.org/si...567_259387.jpg

P. fabia .spots whitish yellow.
Uppersde dark-shaded brown. cellspot notched/horseshoe.
Spots 2, 3 & cellspots close together.
https://www.ifoundbutterflies.org/si...238_236337.jpg

P. fatua.Spots distinctly yellow . Spots tightly conjoined ;strongly reddish/chestnut brown.

P. festa.Spots distinctly yellow in male, white in female ;spots 2, 3, & cellspot tightly conjoined. ground dull ochreous.

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.
