Subcallus with pale brown tomentum, no hairs; parafacials and face pale brown, with long black hairs; beard black. Antennal scape and pedicel greyish brown, with black hairs, pedicel with slight dorsal anterior prolongation; flagellum pale orange; basal plate relatively narrow, with small dorsal tooth.
