This paper provides the first illustration of the male genital capsule of Asuridia rubrimargo (Hampson, 1894) and female genital capsule of Asuridia miltochristoides Rothschild, 1913 after 131 years and 112 years, respectively, of their first description. Originally, both the species were described solely on the basis of external characters. We report A. rubrimargo for the first time outside of the type locality (i.e, from Arunachal Pradesh, India) and update its distribution. A checklist of the genus Asuridia Hampson, 1900 is also provided.
