Hi.
There are a lot of Rhombodera-species with such a shield. Differences may be minimal, as between all the Hierodula species. It seems in this context, that there is also no Hierodula grandis in stock, but just H. membranacea. The problem is, that all the Hierodula complex comprises more than 100 species, some of which may turn out to be not valid. But, who should find the time for a revision?
Regards,
Christian
