Identification - Gromphadorhina portentosa and Princisia vanwaerebecki

[kamil kowalski]

Hello

How to distinguish

Gromphadorhina portentosa

from:

Princisia vanwaerebecki

?

Are they always differ on what the photograph in the Annex?

On the photographs are males - and as is the case of females?

Do you:

Gromphadorhina portentosa

and

Princisia vanwaerebecki

varieties have the same color? that is, blacks and

"tiger"?

What they have color variations?

I greet all

Kamil.

The so-called princisia readily cross with G. portentosa. The way to tell them apart is the notch in the pronotum but of course a few other genera have the same character and sometimes G. portentosa as well. They are "both" highly variable in coloration in the wild.

Females can't be differentiated.

[Zephyr]

Is it possible they're both just G. portentosa?

[BugmanPrice]

I think that is the question Orin raises.

Thanks

And you can designate them the key to the species [Gromphadorhina]?

I think that is the question Orin raises.

I have been told that while a grandidieri does exist in the wild, we don't have it in culture. I bring this up as instead we have misidentified out G. Portentosa as such.

As for P.V.? I am trying to determine yet whether the same thing is true or if we do have them in culture.
