Spotting

ChunXingWong, ironically, I do my best to help also knowing that this picture is tricky.

I agree with Caerostris but not Caerostris sumatrana ... i think the big red dot on its back can help, it's really visible and inevitable.
Thank you very much !

Hello arthroprod, this could be a Caerostris spider, maybe Caerostris sumatrana. Please understand that International Spider Survey is only a mission, not a group of arachnologists.

Looking forward to see more great Arthropod spottings from Danum Valley.

Nobody from "International Spider Survey" can put a name on this beauty ?

I am thinking this is some kind of tent spider due to the large abdomen compared to the cephalothorax, but I am not sure.
