. Colour: Mostly dark brown, frontal vitta velvety black and broadly convex anteriorly, orange to brown posteriorly; pedicel orange with short black setulae, first flagellomere orange with pale setulae. Palpus black. Epicephalon glossy brown, reddish to dark brown anteriorly; paracephalon microtrichose. Notum with conspicuous silvery microtrichose vittae laterally and sometimes with less conspicuous narrow vittae in central darker area, thoracic pleuron with vertical to diagonal silvery microtrichose bands.
