in exhibiting tortuously anastomosed elytral striae, though in this species all striae from the sutural to 7th stria are involved (Fig. 49C). This species also differs in the relatively broader pronotum; MEW/MPW = 1.47 versus a ratio of 1.64-1.67 for the former species. The pronotum itself is broader, more transverse, MPW/PL = 1.38, versus MPW/PL = 1.21-1.26 in
