Eutaenia alboampliata Breuning, 1965 has been described from Laos and is present in Vietnam (as you have seen on the forum), two countries far from Malaysia. We need to check whether they are really the same species.
This specimen was collected in Chiang Mai, February 1997. I am currently cataloging my collection of Asian specimens and this specimen has been in my collection for many years. It is available if someone wants to study if they are the same species. Saludos Sergio https://www.researchgate.net/profile/Sergio-Devesa/research
