(3) The annulignatha group

( Figs 6 c−8c)

Diagnosis. Moths of the annulignatha group share a dark forewing with two small yellow costal spots and a small dorsal spot ( Fig. 6c ). In the male genitalia ( Fig. 7c ), the uncus is bifurcate apically; the gnathos is circular, in some species with a distinct ventral plate; and the sacculus is separated from the valva entirely, often with one or two distal processes. In the female genitalia ( Fig. 8c ), the ductus bursae is sclerotized entirely or partly, or membranous with granules; and the signum of the corpus bursae is usually absent.

The annulignatha group includes one known species.
