Introduction several species that have been placed in some related genera including Cryptolechia could be transferred to this genus. The The genus Meleonoma Meyrick (Type species: Cryptolechia sto- distributional range of the genus extends from India and Sri Lanka to mata Meyrick, 1910) was originally placed in the family Oecophor- the Russian Far East, including Indonesia and Nepal, and few species idae (Meyrick 1914). The taxonomic position of the genus has are known in Madacascar, too. In Korea, the genus is introduced for remained under debate, as well as other related genera including the first time, but Meleonoma malacobyrsa (Meyrick), which origi- Periacma Meyrick.

In the present erroneously attributed to Cosmopterigidae without any comments, paper, two species that were collected from Jeju Island are described and subsequently this error was followed by several authors: Li and as new to science, and are attributed tentatively to the family Wang (2002, 2004) described five species from China, belonging to Lypusidae following Lvovsky (2015).
