Female Euthalia monina.
In FW space 1b, near the base are two small spots, one flat.
Tanaecia only have a single large spot in the same place.

Hi Dr Seow,
I went to look through my Tanaecia photos and maybe you could double check them, see if anything is different.
1. This one should be a typical example of T. pelea

2. This one the HW arrows seem different from the typical T. pelea, shot last year April at Rifle Range Link. The photo size is too large to upload here so here's the iNaturalist link

Both are typical Tanaecia pelea.
Of the similar species only Tanaecia munda is recorded in the past.
The arrowheads in T palguna & munda are set nearer the outer margin than the inner border.
The males of T. palguna & munda have a more tapered HW & stouter built, ie like a male Euthalia.

Since only T. munda is recorded from Singapore, it is best to concentrate on this species.
The HW have more white & the arrowheads are sharper.

This is still a female T. pelea.
Note in particular each of the white spots have the inner borders narrowly tapered.
These females T. palguna & T. munda have been DNA barcoded.
The inner borders of the FW white spots are broadly rounded.

It is regrettable that the specimen of the female T. palguna shown in the research article is actually a female Euthalia monina.
Note the double small spots in FW space 1b sub-basally.

REViSION.
Having look & compare with the female T. munda in the corrigenda of C&P5, this could possibly be a female T. munda.
https://www.mothsofborneo.com/Corrig...Nov12_2021.pdf
This female is identical to the female T. munda in the Corrigenda of C&P5.
https://a4.pbase.com/o6/25/686825/1/...aia_female.jpg
Typical male & female T. pelea. HW arrowheads tend to be midway or nearer the inner border of the marginal zone.

T. munda HW arrowheads always nearer outer margin in the male, midway in the female; HW more white.
Singapore male. HW tapers to the tornus.

Note; Needs a male to confirm the presence of this species.

Many thanks, Dr Seow for the added insights to the distinguishing features of both sexes of T. munda.
We need to work harder and probably spend more time in Ubin in our search for T. munda.

Tanaecia aruna aruna in Singapore ?
This observation is interesting in that the FW arrowheads ,rendered in white are separated from the series of postdiscal spots to the inside.
https://www.inaturalist.org/observations/137292791
https://inaturalist-open-data.s3.ama...783/large.jpeg
In all the three other similar species in P. Malaysia the white area to the inside of the arrowheads are not separated as distinct spots.
T. pelea male.

Tanaecia is very variable & the subspecies from nearby islands eg Sumatra ,Borneo are very confusingly different.
This looks almost certain to be T. aruna but one can not rule out a form of T. pelea say from Borneo, an escapee from a butterfly farm.
Better pix will help to confirm the ID.
TL Seow: CHeers.
