I don't think this distinctive specimen matches the taxon we have called 'Palaeosia undbescribed species', but I'm yet to find a match. It may perhaps be a Threnosia (genus) species, but again I've yet to find a match.
This moth has a white white band along the costa and an adjacent dark band which does not extend right down to the forewing tip. Some P. xiphistola speciemns seems to show this feature https://www.inaturalist.org/observations/240308354 But it also seems to me that P. pilipes is also a possibility given the angle of the photos taken here which may have hidden the 'fingering' of the dark band towards the foreing tip which we usually see in that species.
P. xiphistola has much smaller palps, broader dark band and minimal pale band beside it. P. pilipes has the right wing markings assuming we can't see the feathering on this angle. It also has BIG palps.
