It seems P. panda is the commoner species & P. pandita is the much rarer.
The correct images of both species are based on the UpF spots arrangement & there is no ambiguity between the two species , ie. the spot arrangement is distinct for each species.
The spots are also distinctly yellow in P. panda.
All correct images are male & the antennal colour of the female can only be inferred at.
Pedesta is very closely related to Halpe which also show similar antennal tip colour.
Species like Halpe zema, zola & ormenes have the antennal tip orange with a white dot in both sexes.
H. zema.
Male.
