I can't believe that I forget this family! Here's the first member of Euphaeidae: Anisopleura furcata. There are three Anisopluera species recorded in Thailand. Two are in North Thailand and another one is in the South. A. furcata lives in the North and co-occurs with another one: A. subplatystyla, the species previously known only from India. A. furcata is the commonest species you can see in Thailand.

female

Anisopluera has a unique characteristics: at base of hindwings are angled. Male is black striped with greenish yellow or yellow as shown in the photo above. The tip of forewings have small brownish spot. S9-10 is pruinosed. Superior appendages are forked. Female is similar to the male but lack of the brownish spots in forewing. Base of the wings are red (maybe it's resulted from just emergence). 

You can find this species in North Thailand at 1,000-1,500 m. in May-November.
