Halpe burmana or similar?

[DaveChiangMai]

Another Halpe species from nc Thailand. Forest at 760 metres.

The underwing pattern strongly resembles H. burmana (which is known from this region), but the single cell spot on the upperwing appears to be incorrect (males on Yutaka show double cell spots). Females show one only?

Other possibilities could be H. wantona or H. arcuta. But on both these species the two larger inner spots on the forewing are closer and more overlapping, which does not match this photo. I can't reconcile a good match for both the upper side and under side. Any suggestions please? Thank you.

It should be Halpe wantona.

The HW does not have a central band.
The HW dark interneural spots form a series of pale spots on their outer margins. The lowest in space 1b is the largest.

Similar.

H. arcuata & veluvana both have FW spots 2 & 3 broadly overlapping.

H. handa is similar but FW is always without a cellspot & UnH have the veins in the pale ground area darken.

H. wantona & pelethronix are very similar, but Yukata's image of H. pelethronix have the underside marks poorly contrasted.

H. wantona.
