The family Erebidae is acknowledged as a highly diverse group in Lepidoptera. The genus Ischyja Hübner, 1823 has been known from India, Thailand, Laos, Vietnam, southern China, Borneo, and Sundaland, predominantly in the old world tropic region. This research presents identification of two species, which have been in Vietnam for the first time. With these new findings, the total number of Ischyja species has increased to four. We present a checklist of them, including descriptions and illustrations of the newly recorded species.

The subfamily Pselaphinae is one of the largest groups in the family Staphylinidae. Pselaphine beetles consists of 6 supertribes. The supertribe Faronitae consists of 30 genera worldwide, with 14 genera in Australia and New Zealand. While examining faronite specimens, we separated 366 specimens that did not belong to any known faronite genera. Species of this genus can be separated from other faronite genera by the foveal system, features of the aedeagus, and collection localities which are only collected in the southern part of Australia. Through this study, we describe seven new species and three new combinations that previously belonged to the genus Sagola.

Goniaceritae is the most speciose supertribe of the subfamily Pselaphinae with more than 3,000 species worldwide. Brachyglutini is the only tribe within New Zealand Goniaceritae, comprised of 8 genera. Physobryaxis Hetschko is monotypic genus of the subtribe Brachyglutina. Although the adults of P. inflatus is close to the members of genus Gastrobothrus Broun, 1882, it is characterized by median antebasal fovea and antebasal sulcus on pronotum. In this study, we report six species of Physobryaxis examining 21 specimens. Illustrations of the habitus, diagnostic characters including male genitalia, and key to the species are also provided. Additionally, we present a distributional map divided into areas based on Crosby’s code.

Currently 41 valid species of the Pholcus phungiformes-group (Araneae: Pholcidae) have been known from Korea. In this study, four new species of this species-group were discovered from Gangwon-do and eastern Chungcheongbuk-do. These new species have common characteristics with Pholcus socheunensis, such as broad and membranous prolateral process and strongly curved pseudoappendix in male palp. The female of Pholcus montanus in the original description is the misidentification of a new species. Brief diagnosis, photographs and a distribution map of the new species and P. socheunensis with discussion on their sympatric distribution are provided.

본 연구에서는 한국산 미기록속인 밑들이자루맵시벌속(신칭)과 미기록종인 밑들이짧은자루맵시벌(신칭)을 처음으로 보고한다. 밑들이자루 맵시벌속은 잎벌류에 기생하는 것으로 알려져 있으며, 배마디 끝부분이 위쪽으로 굽어져있는 것이 특징이다. 본 논문에는 미기록속, 미기록종의 기 재문과 사진을 제공한다.

국내 미기록속인 Ectopsocus를 미기록종인 E. briggsi McLachlen,1899 (외다듬이벌레; 신칭)와 함께 보고한다. E. briggsi은 한반도의 남부지 역인 거제, 진주, 울산, 제주에서 채집되었다. 이번 연구에서 이 종의 정확한 동정을 위해 외형과 진단형질의 사진을 제공한다.
