An Ypthima sp from n Thailand

[DaveChiangMai]

On a recent trip to Omkoi (n Thailand) I photographed these two Ypthima sp (two individuals), that were in an area with many Common Fivering Y. baldus, and looked very different. I would appreciate some comments on these two, which I assume are the same species. The spacing between the ocelli looks very different to others I have in my collection (especially the spacing between 3 and 4 on the hindwing), plus the shape of the ocelli is slightly oval. I am thinking these could be Pallid Fivering Y. savara or maybe Malayan Fivering Y. nebulosa. Y. lisandra can be ruled of as the lower three ocelli are not in alightment.

Many thanks.

Ypthima is another terribly difficult genus.
WSf have the strae sharply defined ;in dsf they are fuzzy.
So these two are wsf or intermediate forms.

Y. savara. large FW 24-26 mm. HW twin dark fascia rather straight & parallel throughout.

Y. nebulosa. HW dark fasciae curved.In peninsular Malaysia this is known as Y. horsfieldi humei (complicated story)
Ground usually whiter & striae more contrasting.
Uemura states the upperside FW ocellus have a round yellow ring , but his images do not bear this out.

Y. singorensis; similar to Y. baldus but smaller .FW < 18mm.

THey are likely to be intermediate forms of Y. baldus.

TL Seow: Cheers.
