Baoris ,most likely Baoris oceia.

The uniform grey brown colur is typical.
The FW spottiing is much reduced, and both cellspots are missing.
The ID of Baoris is very difficult.

The two species in Singapore tend to have reduced spotting in the male more so in B. oceia.
It is assumed that the darker blackish one is B. oceia and the lighter brown one B. farri.
In the past I thought the one with a narrow crescentic upper cellspot to be male B. oceia, because all male B. farri in eg China,India appear to have rounded cellspots.
eg.

This is no longer true, and the presence of an upper cellspot is more suggestive of B. farri.


Thus, probable ID criteria.

Baoris farri.
Lighter brown.
Male more spotted, especially an upper cellspot.
Males.

Baoris oceia.
Darker blackish brown.
Male with upper cellspot usually absent.
Males.

Female.

Note: These assumptions may not be correct.


Caltoris cormasa is usually recognizable by a strong reddish tone to the ground colour, provided the camera colour balance is correct.
More often with three small subapical spots.
HW is deeper red brown and darker.
Antenna should have a visible pale area.
HW veins are not prominently raised.
Males.

This is likely to be ssp. parkeri overexposed.

SSp. malayana is very dull ochreous brown on the HW.

Ssp. parkeri is lavender on the HW, ie very pale purplish.

They are both Mycalesis perseoides..
Two species in Singapore have the peripheral white striae enhanced.

M. perseoides have the indentation formed by the inner margins of the eyespots ragged and irregular.
The dark discal line is strongly & irregularly toothed.

M. visala have the indentaion formed by the inner margins of the HW ocelli less irregular.
The dark discal line is more regular and less toothed.

Intermediates between the two species occur.


M. orseis always have a full series of bright yellow-ringed ocelli.
The white discal band is broad and close to the ocelli.
The peripheral zones are mainly light brownish.
