Acryptolechia Lvovsky, 2010[1] Meleonoma is a genus of moths in the family Autostichidae.

Meleonoma was established by Edward Meyrick in 1914,[2] who placed the genus in the family Oecophoridae.

Park & Park (2016)[4] attributed the genus to Lypusidae sensu Lvovsky (2015), although shortly after, Yin & Wang (2016a[5] & 2016b[6]) placed the genus as incertae sedis within Gelechioidea and then in Oecophoridae, followed by Kitajima & Salamaki (2019)[7] when studying the Japanese species.

Furthermore, Lvovsky (2015) synonymized the genus Acryptolechia (at that time placed in Cryptolechiinae of Depressariidae) with Meleonoma.

More recently, Wang & Li (2020)[8] studied the molecular phylogeny of Gelechioidea, and found Meleonoma plus Phaulolechia formed a clade constituting the tribe Meleonomini, sister to Periacma + Irepacma + Epiracma, constituting the Periacmini, bringing both tribes together to form the subfamily Periacminae, in Autostichidae.
