Distribution. Brazil (states of Amazonas and Roraima), Colombia (Caquetá) (New record) (Fig. 7).
Remarks. Systenus flaviatus is superficially similar to S. naranjensis by the metepimeron yellow and tergites 1–3 partly yellow but can be easily differentiated by the characters present in the key. This species was described from Brazil, and before this work was known only for the type locality at the Reserva Florestal Adolpho Ducke, in the city of Manaus, state of Amazonas.
