True Dr. Seow. These little rascals jump up and down, make us run behind them and when we shoot a photo they are a pain to identify.

But I am optimistic

Yes, the UNH colouration is uneven.

Spot 2 on UPF is usually quadrate in P. mathias, which is not the case in this specimen.
There in no brand on UPF in female. (To check where the imaginary line thru cell spots cut the brand). These two points confused me on the id.

But yes, on the whole pointers are towards P. mathias.

Thank you so much.
