Is this a Princisia vanwerebeki or g.portentosa???
i keep this roacher w/ my others g.portentosa, is possible some kind of hybrid?

PS: sorry about my bad english

Looks like the black morph of G. portentosa.

 

[Stylopidae]

If it is a princess roach, then there's no potential for hybrids. They're from different genera.

I can only tell the males apart.

hmmm that's nice,
but how can i know of it's portentosa or Princisia vanwerebeki???

They look like my G. portentosa colony. I don't think they are Princisia sp.

 

[the_frog_kid]

they are portentosa
Princisia vanwerebeki nymphs have little white marks like nymph six spot roaches




thanx froggy

The problem is in the taxonomy.

A few years ago, was Princisia vanwaerebecki and Gromphadorhyna portentosa, and, of course, animals whith different genera can´t reproduce. Now, there are some Taxonomist that say they are in the same genera: Gromphadorhyna princisia and Gromphadorhyna portentosa.

I think the last one is right becouse the two sp. are very similar, so, the can hybrid.

Now, I´m looking for the differences between G. portentosa and G. princisia (P. vanwaerebecki). Taxonomy use the thorns in the legs to clasiffied the roaches.

Best regards, Javier

Hi!

In my opinion they are Gromphadorhina spec. because of the round form of the Pronotum.
