This could be an undescribed Hyllus sp. found by me and more locals at Malaysia's highland area, if any researcher interested to do any research about this sp. and needs more detail photos for this species, feel free to send an inbox message. I have more detail photos in my folder.
Update: According to some local photographers, this species only seen in highland area and its rarely seen, only few observations available. It's called [Hyllus sp. "Garfield"] by the locals.
Hoping for more information about it.
