Goliathus goliathus female form names?

[martina]

Hi, I have these to amazing females of G. goliathus. I know all the variation names in males, but can find nothing about the females.

These two are interestingly from a locality, where in males only G. goliathus goliathus occur. But big, 10cm is relatively common.  But females are different, colorful. And big too - 7.5cm.

On the other hand, about 300 km west from there, there is location, where all forms of G. gpliathus are, but smaller (never 9cm), but all females are the same nominal form - small and brown.

It puzzles me - there seem to be no difference in the forest, ar elevation.............

Does anybody know the female form names.

The locals know all the males form, but with females, they were clue less - like me :-D

Cheers

I think goliathus females get overlooked much of the time, and can't say I've seen identification for female forms even though there is obviously variation. In cacicus females, I know there can be significant variation, and I would think somebody has taken the time to label them at some point. For the females you posted, they do have interesting elytral patterns-looks like an intermediate form of quadrimaculatus and conspersus, albatus female I guess is what I would say I don't know why the two neighboring populations you mentioned would have such differences in size and form-especially if it is indeed a common trend. Perhaps some sort of a barrier that could be preventing gene flow (deforested areas, large cities, road ways). I don't know how far Goliathus can/will travel in search of mates, so couldn't do anything other than speculate.

On a side note, your specimens are very well set. Thanks for sharing.
