Wang, Shuxia, Zhu, Xiaoju, Zhao, Baixue & Yang, Xiaofei, 2020, Taxonomic review of the genus Meleonoma Meyrick (Lepidoptera: Autostichidae), with a checklist of all the described species, Zootaxa 4763 (3), pp. 371-393 : 377

(7) The facialis group

( Figs 6 g− 8g)

Diagnosis. Moths of the facialis group share a yellow forewing with a dark costal spot and a dark apical patch ( Fig. 6g ). In the male genitalia ( Fig. 7g ), the uncus is sub-triangular, club-shaped, or long spine-shaped; the gnathos is absent or present; and the sacculus is separated from the valva, or only free distally. In the female genitalia ( Fig. 8g ), the antrum is heavily sclerotized in most species, the ductus bursae is sclerotized or membranous, and the corpus bursae lacks or has 1−2 signa.

The facialis group includes 24 described species.
