treatment, the more intensely microsculptured vertex can externally diagnose individuals of this species, with the isodiametric sculpticells upraised, their individual reflections producing a textured look to the surface. Also, the elytral lateral marginal depression is broader laterad the humerus in this species (Fig. 143D). The aedeagus of this species has a broadly rounded median lobe apex (Fig. 144

All diagnostic characters are presented above, so only the various recorded ratios are presented below.] Eyes moderately convex, covering much of the protruded ocular lobes, ocular ratio = 1.44-1.50, ocular lobe ratio = 0.79-0.84. Pronotum transverse, MPW/PL = 1.18-1.30, lateral margins distinctly sinuate for short distance anterad right to slightly acute hind angles, MPW/BPW = 1.54-1.64. Elytra narrowly subquadrate, MEW/HuW = 2.05-2.14.
