Here we review the genus Nycteola of the Nolidae (Lepidoptera). As the result of this study, we recognized already synonymized species N. costalis Sugi, 1959 of N. coreana (Leech, 1900) and newly recorded species N. dufayi Sugi, 1982. Whlie the number of Korean Nycteola species remain unchanged, the composition has been changed.

Family Nolidae has not much been treated as noticeable pest. In other countries, there are some pest species like Garella musculana (Erschoff, 1874), Uraba lugens Walker, 1866, and Earias insulana (Boisduval, 1833), but those are not reported in Korea. Recently, the occurrence of a nolid species, Meganola major (Hampson, 1894) has been increasing, especially in Jeollanam-do Prov. This species is mainly distributed in Indian subregion and Southeast Asia, but also East Asia reported, but until now, there are no outbreak information. Neverthereless, recent outbreak might be lead by global warming, and their growth stage. This seems to be evidence of the potential outbreak risk of nolid moths, but unfortunately, their ecology is not mostly well-studied. In this discussion, we are focusing on the potential outbreak of nolid moths in East Asiatic and Oriental regions.

The genus Nola (Nolidae, Nolinae) was established by Leach (1815), with the Noctua palliola Denis & Schiffermüller, 1775 (a junior subjective synonym of Phalaena cucullatella Linnaeus, 1758) from Vienna, Austria. Nola comprises over 200 species: Africa and western Palearctic approximately described 100 speices (Hacker et al., 2012); Oriental and Eastern Palearctic regions have over 100 species (László et al., 2010; Sasaki et al., 2011; Kononenko and Pinratana, 2013). Two species of the genus Nola Leach; Nola euryzonata (Hampson, 1900) and Nola lucidalis (Walker, 1865), reported for the first time in Laos. Illustrations of adults and genitalia of all the examined species are provided.

The genus Meganola (Nolidae, Nolinae) was established by Dyar (1898), with the type species Meganola conspicua Dyar, 1898, from America (Type locality: Texas, Colorado, Arizona). This genus comprises 80 species described in the Palaearctic and Oriental region. In this study, genus Meganola Dyar is reviewed from Korea, with description of a new species. We redescribed 12 species and one new species. Illustrations of adults and genitalia of all Korean species are provided, with a key to the genus of Meganola based on the male genitalia.

The family Nolidae belongs to the superfamily Noctuoidea comprising about 1,800 described species of 186 genera in the world. In China, a total of 101 species, 45 genera were recorded in ‘Fauna Sinica’ Vol.16, (1999) and in case of Japan, 110 species, 42 genera have been recorded in ‘The Standard Moth of Japan Ⅱ’, (2011). In Korea, a taxonomic study of this family has been carried out by several reseachers: Fixsen (1887), Leech (1888), Inoue (1976, 1982), Oh (2001), Sohn et al (2005), Choi (2006, 2011). However the family Nolidae has rarely been studied in Korea. A total 45 species, 25 genera have been reported from Korea (NIBR, 2016). In the present study, We overviewed the family Nolidae, with illustrations of adults in each genus, add checklist.
