Mandibles with the oval area at the base of the upper fang weakly 

 granular over its surface, the marginal circle of granules coarser 

 and more numerous. The upper fang stout, much less compressed, 

 slightly curving outwards and downwards ; the inner surface evenly 

 convex ; the upper surface wide, evenly convex, neither sulcate,
