 pale, inconspicuous. Postclypeus moderately to strongly inflated, Pcl/W, 0-27-0-36, Pcl/Ri, 

 1-63-2-50. Apical teeth of mandibles short, L A /Li, 0-46-0-53, Ra/Ri, 0-54-0-65; subsidiary 

 marginal tooth of left mandible separated from molar prominence by distinct notch in surface 

 view, complex ratio, LA/Li.L m , 9-63-11-85; point of first marginal tooth of right mandible 

 distinctly behind line of apical to second marginal, anterior edge of first marginal shorter than
