I agreed with Dr. Roger. It should be U. astheniata (previously known as Micronia astheniata. Please refer to "An introduction to the moths of South East Asia" by H.S. Barlow, page 136 and plate 47, fig 2.)
My knowledge about moths is very poor, must learn from the experts. When was it transferred from genus Micronia to Urapteroides and why?
