Face as frons, ventral part around oral margin and on gena shining black with dispersed greyish pollinosity and without distinct pile; facial tubercle oval shaped, weakly developed. Vertex with orangebrown pubescence and dark yellow medium long pile; continued along occiput, anterior margin in ventral two-thirds conspicuously silvery pollinosity, ventrally with dispersed pale pile.
