Diagnosis. The species is similar to R. acciusalis. In the male genitalia, this species has a spinose area and a blunt sclerotized plate at apex of aedeagus, while R. acciusalis has two spinose areas and two triangular pointed sclerotized plates. Besides, the shape of the subteguminal process is also different between R. acciusalis and R. minima. Additionally, R. minima is distinctly smaller than other species of this genus.
