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.

The genus Patania Moore, 1888 (Lepidoptera, Crambidae) has been recorded in Korea with nine species: P. balteata (Fabricius, 1798), P. brevipennis (Inoue, 1982), P. chlorophanta (Butler, 1878), P. deficiens (Moore, 1887), P. expictalis (Christoph, 1881), P. punctimarginalis (Hampson, 1896), P. ruralis (Scopoli, 1763), P. sabinusalis (Walker, 1859) and P. harutai (Inoue, 1955). In this study, we describe a new species P. gorosoe Lee, Heo & Bae, sp. nov. which very similar with P. harutai. The host plants of above two species are clarificated. Illustrations of adults and genitalia of P. harutai and P. gorosoe sp. nov. are provided. A checklist of the genus Patania in Korea is also provided. [Zoobank registrations: Patania gorosoe Lee, Heo & Bae, new species: LSID: urn:lsid:zoobank.org:act:3FFD8DA8-8EA1-423A-84A9-BC5804E18EA0]

A review of the larval host plants of the family Gelechiidae in Korea is provided. The data is mostly based on results of the survey on the larval host plants for the lepidopteran species by the second author since 2008, and a part of them is from the previous data by the first author and co-authors (Park 1983, 1991; Park et al. 2020, 2021; Park & Ponomarenko 2007). Of the 53 listed species of Gelechiidae in the present study, larval host plants for the 7 known species of Gelechiidae are reported for the first time (Table 1). Also, 21 species which the host plants are newly recognized from Korea in this study are listed in the Table 2.

One species of Noctuidae, Chytonix brunneofascia Choi and Heo sp. nov., and three species of Erebidae, Gynaephora atrata Choi, Heo and Kim sp. nov., Utetheisa pulchelloides Hampson, and Pilipectus prunifera (Hampson) were newly recorded from Korea. This paper provides the diagnosis, descriptions of the adult and larva, and genitalia of the available species.

In this study, two new species of the family Gelechiidae are described from Korea. The new species are Teleiodes juglansivora Park & Byun, sp. nov. and Encoplata najuensis Park & Byun, sp. nov. For the new species, some biological data concerning on their larval food plants are given.

From the result of a study based on the material reared from larval stages of some microlepidoptera, two new species of Gelechiidae (Dichomeris cuneatiella Park, sp. nov. and Euscrobipalpa lyratumella Park, sp. nov.) are described, and three species of the family (Paralida triannulata Clarke, 1958, Dichomeris okadai Moriuti, 1982, and D. ochthophora Meyrick, 1936) are reported for the first time from Korea. For all these species, biological data including their larval host plants are provided. Of them, the host plant for D. okadai (Moriuti, 1982) is reported for the first time.

In this study, a genus Eretmocera Zeller, 1852, is reported for the first time from Korea, with a newly recorded species of E. artemisiae Li, 2019. External and genitalic characteristics of the newly recorded genus and species were illustrated and redescribed briefly, with biological information.

In this study, we found a newly recorded species, Depressaria colossella Caradja, 1920, on Zanthoxylum schinifolium (Rutaceae) for the first time from Korea. Diagnosis, description and illustrations of adult and genitalia are provided with new host plant information. A checklist of the genus Depressaria in Korea is also provided.

This paper reports four species of Erebidae from the southern part of Korea: two Boletobiinae, Honeyania ragusana (Freyer, 1845), Enispa masuii Sugi, 1982, one Hermininae, Adrapsa ablualis Walker, 1859, and one Arctiinae, Stictane rectilinea (Snellen, 1879). Honeyania ragusana can be distinguished by the following: a blackish dot on the apex of the forewing with strongly curved medial lines, a long slender uncus and a strongly distally bifurcated valva with a large distally expanded costa and a thumb-shaped process of sacculus on the male genitalia as well as a sclerotized antrum, strongly tapered ductus bursae, and large corpus bursae on the female genitalia. Enispa masuii, a lichen feeder, can be distinguished by the whitish medial lines of the grayish fore- and hindwings, and a pair of rounded ball-shaped lamella antevaginalis, long, sclerotized ductus bursae, and pear-shaped corpus bursae without signum of the female genitalia. Adrapsa ablualis can be distinguished by the whitish medial lines of the fore- and hindwings and large medial process of the costa and dentate distal margin of the valva of the male genitalia. Stictane rectilinea can be distinguished by the broad dark grayish medial band of the forewing and the long knife-shaped valva with a strongly hooked process on the distal part of the sacculus of the male genitalia.
