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 : 376

(1) The malacobyrsa group

( Figs 6 a−8a)

Diagnosis. Moths of the malacobyrsa group share a broad lanceolate yellow forewing with a wide blackish brown postmedian fascia ( Fig. 6a ). In the male genitalia ( Fig. 7a ), the uncus is more or less conical or rod-shaped; the gnathos is absent; the valva is blade-shaped in most species; the transtilla is dilated roundly or enlarged irregularly; and the sacculus entirely separated from the valva. In the female genitalia ( Fig. 8a ), the antrum is heavily sclerotized or membranous; the ductus bursae is widely sclerotized or narrowly membranous; and the rounded corpus bursae has 1−2 signa.

The malacobyrsa group includes four described species.
