In R. goiana the dorsal pubescence is more compact, the upper eye lobes are narrower (Fig. 11), with largest width about as wide as basal width of scape, and the distance between upper eye lobes is equal to 3.0 times the largest width of one lobe. It differs from R. flaveola Martins & Galileo, 1985 mainly by the femora being darker (reddish in R. flaveola), and by the elytra without distinct contrasting areas of pubescence (present in R. flaveola).
