Background: The genus Nycteola Hübner has been mainly distributed in the Old World and usually feeds on Fagaceae and Salicaceae, but Myrtaceae and Juglandaceae have also been reported. In Korea, the number of this genus has been changed from four to three after 2007, but three or four species are listed confusingly up to now., New Information: The Japanese endemic species Nycteoladufayi Sugi, 1982 are firstly reported for the Continents with its brief biology. Additionally, Korean fauna of nycteolid species are reviewed., (Yeong-Bin Cha, Un-Hong Heo, Ulziijargal Bayarsaikhan, Sora Kim, Yang-Seop Bae.)

Two new species, Stericta jaeshini Kim & Bae, sp. nov. and S. atroaurantiaca Kim & Bae, sp. nov. are described from Southeast Asia. About 50 species of the genus Stericta have been recorded from Southeast Asia, but it has not been recorded to occur in Laos and Cambodia previously. We record the presence of this genus in these two countries for the first time in this study. Illustrations of adults and genitalia of examined species are provided. v.

One new species of Olethreutes Hübner, 1822 species, O. oculata Kim, Byun & Bae, sp. nov., is described, and two related species, O. captiosana (Falkovitsh, 1960) and O. subtilana (Falkovitsh, 1959), are redescribed from Korea. Color figures of adults and images of genitalia are provided. [Zoobank registrations: Olethreutes oculata Kim, Byun & Bae, new species: LSID: urn:lsid:zoobank.org:act:814E618C-C13D-4FAC-A669-C3AD8673227F].

Females of S. kualabohi and S. cambodensis are studied for the first time. Illustrations showing the general view of the body of adults and genitalia of all examined species from Thailand are provided.

A new species, Halone arcuata sp. nov. is described from Vietnam, and a new combination Halone bucseki (ern, 2009), comb. nov. is proposed. A diagnostic comparison between newly described species and H. viktorai Bucsek, 2014, H. solitus Bucsek, 2014 and H. hollowayi Bayarsaikhan Bae, 2019. Adults, male and female genitalia of all species mentioned are illustrated.
