Family Tineidae, belongs to the superfamily Tineoidea, with about 2,500 described species belong to 450 genera, and 16 subfamilies all over the world (Robinson, 2009). Classification of this family studied by Zagulyaev (1972), Robinson (1988), Davis & Robinson (1998), Nieukerken et al. (2011), and Regier et al. (2015), etc. The family was reported 33 species belonging to 19 genera of eight subfamilies in Korea up to date (Paek et al., 2010; Park et al., 2012; Byun et al., 2014; Lee et al., 2016; 2017a; 2017b; 2018). In this study, a total of 42 species belonging to 22 genera of nine subfamilies are recognized in Korea. Among them seven species are reported from Korea for the first time, and two species are described new to science.

Metcalfa pruinosa (Hemiptera: Flatidae) is a invasive and harmful insect in South Korea. It is originated from the Nearctic region. Since M. pruinosa was first identified in South Korea in 2005, it dispersed throughout the country. In this study, we investigated the dispersal ability of M. pruinosa in the field in three different levels: 1) short distance movement, 2) flying movement, and 3) dispersal distance in large area in the two different landscape types (open canopy and forest with covered canopy). Our results showed that the movement ability of M. pruinosa was weak in walking. However, it displayed long dispersal distance that increasing dispersal distance in each year. These results can be used for modelling dispersal distance of the species.

The genus Pachynoa Lederer, 1863 reported 13 species in the world. This genus was established by Lederer, 1863 have been treated within the genera Pitacanda Moore, 1886 by Hampson, 1896 and Hypermeces Turner, 1933 by Shaffer et al., 1996. Species of the genus Pachynoa are mostly distributed from India and Taiwan to Solomon island. In this study, the genus Pachynoa is newly recorded in Laos with two species, Pachynoa xanthochyta (Turner, 1933) and Pachynoa thoosalis (Walker, 1859). These species are redescribed with illustrations of the adults and the genitalia, and their distribution is updated.

The genus Coptotriche belongs to leafmining family Tischeriidae, comprising about 60 species in the world. They live in inside leaves during immature stage; larvae feed on tissue of the leaf, producing mining trace. The pupa also spend in the mine, and emerge to become a adult from the mine. In Korea, two species, C. angusticollella and C. heinemanni, are reported and are known as pest about Rosa multiflora and Rubus crataegifolius respectively. In the present study, we review three species of genus Coptotriche in Korea with a new species. Brief descriptions and illustrations of the adults, male and female genitalia, larvae, pupae, and host plants are provided.

The Pyraustinae is one of the large subfamily in Crambidae. In Korea, more than 60 species in 20 genera of the Pyraustinae have been reported. Recently, Demobotys pervulgalis (Hampson, 1913) and Ecpyrrhorrhoe dissimilis (Yamanaka, 1958) were recorded by Choi et al. (2015). Among of the Pyraustinae, the genera Callibotys and Sinibotys were established by Munroe and Mutuura (1969). In this study, we report two species of genera Callibotys and Sinibotys from Korea for the first time, with a newly recorded genus Callibotys. Illustrations of adults, male and female genitalia, description 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.

Three species of the genus Glaucocharis Meyrick (Lepidoptera, Crambinae) are reported for the first time from Korea: G. melistoma (Meyrick), G. rosannoides (Bleszynski), and G. vermeeri (Bleszynski). The description, distribution, image of the adults, males, and females genitalia are provided. Also, checklist of the genus Glaucocharis from Korea is present.

The family Tischeriidae belongs to superfamily Tischerioidea, comprising four genera and 115 species. Tischeriidae is known as a leafminer, Tischeriid larvae feed between the leaves of the host plants through all instars. In Korea, two genera and four species have been recorded. recently, Sohn (2007) reported one species and Byun et al (2009) arranged checklist of Tischeriidae. In the present study, we provided checklist of this family, including a newly recorded species from Korea. Brief descriptions of species and illustration of adult and genitalia are provided.
