However,  A. globosusis a nomen nudum,lacking a proper description and illustration, and is a secondary homonym of  A. globosus(Bronn, 1831). Consequently,  A. globosusis an invalid name and cannot be employed. Therefore, the accurate course of action is to reinstate the name  I. anomala,as proposed here.
