Mandible with six teeth; mandibular dorsum coarsely rugose. MOD ranging from 0.16-21x HL. In profile, eyes situated slightly anterior to middle of head, OMD = 1.001.30x MOD. Antennal scapes moderately long (SI = 67.3279.79), failing to reach vertex by length of basal funicular segment; base of scape flattened dorsoventrally, ventral surface widened at base with moderately well-developed inferior basal flange, margin of flange weakly carinate; entire scape with weak longitudinal striae, moderately granulate-punctate, weakly shining.
