Thanks Orin! I was about to ask about those "brown wing" craniifer. It seems like classification of roaches is pretty confusing, isn't it?Blaberus fusca are also known as Blaberus craniifer "ugly" or "brown wing" in Europe. The two are closely related and can obviously interbreed (all the 'hybrid' Blaberus are a cross of these two, the vendors that say B. giganteus are 'in' the hybrids are offering false info./ wishful thinking). If the same criteria were used for Gromphadorhina and "Princisia" there would likely only be one species.
