AL , PPW , PPL , PPI 78-94 (n = 20). Mandibles generally smooth and shin- ing, with a few basal longitudinal rugae. Masticatory margin of mandible with four teeth: an apical + a preapical + a long diasteina + two small denticles that are roughly the same size. Basal margin of mandible lacking a toothlike prominence. Clypeus shining, with a median longitudi- nal carina; sometimes a few additional su- perficial rugae present. Ventral surface of clypeus usually with a long transverse ruga. Anterior clypeal margin usually with seven denticles (a median one and three others on each side), but in some specimens, one to two denticles weak or rudimentary. Palp formula 1,3. Frontal carinae just extending to the level of the posterior margins of eyes. Slightly concave scrobal areas pres- ent lateral to the frontal carinae. Frontal lobes weak so that the antennal articula- tions are almost entirely exposed. Antennal scapes long, sui-passing the occipital mar- gin by one-fourth to one-third of their length. Fyes usually containing over 10 ommatidia in the longest row. Profile shape of alitrunk and pedicel segments as in Figure 129. Pronotum armed with a pair of exceptionally long spines that are about to and longer than the dis- tance between their bases. Propodeum.
