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.
