Longitudinal rugae on cephalic dorsum coarse, wavy to irregular medially, becoming more irregular to rugoreticulate laterally. Cephalic interrugae moderately granulate-punctate, weakly shining. Anterior margin of clypeus weakly convex with very small medial tooth; dorsum between antennal insertions with 9-12 fine, closelyspaced, longitudinal rugae, interrugae dull to weakly shining. Mandible with six teeth; mandibular dorsum coarsely rugose. Up to several moderately long, curved, bristle-like, yellowish hairs project from anterior margin of clypeus. Eyes small, MOD = 0.18x HL. In profile, eyes situated anterior to middle of head, OMD = 1.09x MOD; several hairs project from between ommatidia. Antennal scapes long (SI = 79.07), surpassing vertex by less than width of basal funicular segment; entire scape with moderately coarse, longitudinal striae, dull to weakly shining. Basal flange of scape well-developed with carinate margin. Psammophore poorly-developed, consisting of numerous medium to long hairs scattered across ventral side of head.
