This new and very interesting species is brownish-grey ; the 

 upper surface is covered all over although not densely, with 

 brown short bristles. The head is rectangular, the anterior 

 edges rounded, the anterior margin somewhat excavated. The 

 labrum is short but broad. Before the eyes exists a rounded 

 tooth and the posterior edges are also not acute. 



The ocular canthus is narrow. The mandibles are similar 

 to those of G. tricuspis Eits.
