Hello Loong Fah, not easy to picture. I hesitate between Cerosterna perakensis Breuning 1976 and Cerosterna variegata (Aurivillius, 1911). But Apriona vagemaculata (Breuning, 1948) also looks like.
Having looked at the picture in your post on Apriona vagemaculata and checked against my own specimen, I think it is an Apriona vagemaculata (in particular, the pronotum sculpture and the relative proportion of the ventrites match much better).
Malaysia: Apriona: vagemaculata
