Type material. Lamprotatus zipoetes Walker. One female, LECTOTYPE, 

 bearing a Waterhouse label. Agreement with the description is poor, hence I adopt 

 the name grandiclava, which has already been recognized and which is represented 

 by a type specimen in good condition. An application for the conservation of the 

 name Gitognathus grandiclava Thomson is being submitted to the International 

 Commission on Zoological Nomenclature.
