A new and an unrecorded species of the family Psychidae (Lepidoptera) from Korea, with an annotated catalogue

Abstract In this study, a total of nine species of the family Psychidae were recognised from Korea. Among them, Psyche yeongwolensis sp. nov. is described as new to science. Also, a species, Proutia maculatella Saigusa et Sugimoto, is reported for the first time from Korea. All available material were dissected and illustrated. Also, an annotated catalogue of the family Psychidae from Korea is provided.

First Report of Larval Damage to Liriope spicata by Mahasena aurea (Lepidoptera: Psychidae) in Korea with a Redescription of External Morphology of the Larva and Adult

In this study, one species of the bag moth, Mahasena aurea (Butler) (Lepidoptera: Psychidae), was found for the first time in Korea as a new insect pest on leaves of Liriope spicata (Thunb.) Lour. Also, the female larvae and adults of the species were first collected in this country. Larvae, pupae, and adults of both sexes are redescribed with illustrations of all external characteristics including the genitalia of the male.

Four Newly Recorded Species of the Family Crambidae (Lepidoptera) from Korea

This study was carried out to report the newly recorded species of the family Crambidae, belonging to the order Lepidoptera. During the course of investigation on the family Crambidae in South Korea, the following four species are reported for the first time from Korea: Diplopseustis perieresalis (Walker, 1859), Dolicharthria bruguieralis (Duponchel, 1833), Herpetogramma ochrimaculale (South, 1901), and Omiodes diemenalis (Guenee, 1854). Among them two genera, Diplopseustis Meyrick and Dolicharthria Stephens, are also newly reported from Korea. External and genital characteristics of adults were examined and illustrated. All of the newly recorded species were enumerated with their available information including the collecting localities, illustrations of adults, and genitalia.

Two new species of the genus Dahlica Enderlein (Lepidoptera, Psychidae) from Korea

Abstract The genus Dahlica Enderlein, 1912 is reported for the first time from Korea with two new species: Dahlica (Dahlica) somae Roh & Byun, sp. n. and Dahlica (Dahlica) ochrostigma Roh & Byun, sp. n. Adults and genitalia are illustrated, and DNA barcodes for precise identification of the species are also provided.

Insect community structures along elevation gradients on Mt. Seongak-san, South Korea

Insect communities along three elevation gradients on Mt. Seongak-san, South Korea, were investigated from May to September 2013 using traps in order to collect basic data for distributional monitoring of species in a forest ecosystem. A total of 2698 individuals of 309 moth species of 18 families were collected in bucket-light traps, along with 196 individuals of 26 ground-beetle species and 11,276 individuals of 14 ant species in pit-fall traps. The insect community at each site was analyzed using analysis of variance and non-metric multidimensional scaling (NMS). The ground-beetle and ant abundances varied with elevation. The NMS showed distinct clusters of moths between the ground-beetle and ant distributions with elevation and month. The community-level responses of these insect groups to those gradients were analyzed.
