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

( Figs 6 h−8h)

Diagnosis. Moths of the acutiuscula group share a dark forewing usually with two small yellow costal spots ( Fig. 6h ). In the male genitalia ( Fig. 7h ), the uncus is clubbed, the gnathos is absent, the transtilla is narrowly extended or dilated, and the sacculus is not separated or only distally separated from the valva. In the female genitalia ( Fig. 8h ), the ductus bursae is sclerotized entirely or partly, and the corpus bursae has 0−2 signa.

The acutiuscula group includes five known species.
