Looking for Curetis bulis in Singapore.

[Psyche]

Curetis bulis is a fairly common Sunbeam that although recorded in Singapore before appeared to have become extinct.
It is very easily confused with C santana on the underside.

There appeared to a lot of error images, not just on the net but with the reference books as well.
The errors which had cause so much confusion are:

Yutaka website. A series of C. acuta images had been inadvertently added to C. bulis (Those with pointy angular wings.).
http://yutaka.it-n.jp/lyc3/84030001.html

C&P4 plate 34 no 18 which is the underside of C. bulis & not santana.

Fleming L378 which is the upperside & underside of male C. santana & not C. bulis.
Fleming L379 Un. which is the underside of C. bulis female & not C. santana.


C. santana. HW postdiscal mark (part of the band) in space 6 in line with the mark in space 7.
Submarginal marks in space 6 & 7 out of alignment.
Palpi red-spotted.
Typical male & female.


Less obvious example.



C. bulis. HW postdiscal mark in space 6 often narrow & tuck under & inwards (basad) from the mark in space 7.
Submarginal marks in space 6 & 7 more or less aligned end to end (if present).
Palpi red-spotted.
Two examples. Note red-spotted palpi



A 3rd species with a similar slanting postdiscal band may be mentioned in case it turns up as well.
C. felderi HW postdiscal mark 6 tuck under mark 7 as in bulis, but submarginal marks out of alignment as in santana.
Palpi are white & unspotted.
This example from Brunei have a more extreme inward postdiscal mark 6.




Unfortunately there are no image shot so far of C. bulis.

This website has an image of C. bulis labelled as C. santana purportedly from Singapore.
