Two species of the genus Hypena Schrank, 1802, H. nigrobasalis (Herz, 1904) and H. conspersalis Staudinger, 1888, are reported for the first time from China. Adults and genitalic characteristics of the two species are briefly redescribed, with illustrations and their distribution.

One of the small genera of the tribe Atrophini (subfamily Banchinae), the genus Amphirhachis, has been reported seven species in the world. Among them, four species (Amphirhachis fasciata, A. nigripalpis, A. rubriventris and A. tertia) from Oriental region, and four species(Amphirhachis fujiei, A. miyabi, A. nigra and A. tertia) from Eastern Palaearctic region. Unfortunately, there are no records in South Korea yet. This genus is easily distinguished from other genera of Atrophini following: clypeus strongly convex near side; posterior transverse carina of propodeum represented by a weak or faint vertical ridge at apex on each side; ovipositor sheath shorter than metasoma. In this study, the genus Amphirhachis is recorded for the first time with a newly recorded species (Amphirhachis tertia) from South Korea. New data on the taxonomy and distribution of Amphirhachis tertia are given. We also provide diagnosis and digital images of a newly recorded genus and species.

We report a new distribution of Carex foraminata C. B. Clarke on the Korean Peninsula. This species was first reported in China and is distributed in Jiangxi and Zhejiang Provinces. We found this species on Hongdo Island in Heuksan-myeon, Shinan-gun, Jeollanam-do in Korea. Carex foraminata is similar to the related taxa C. brevispicula G. H. Nam & G. Y. Chung, C. chungii Z. P. Wang, and C. genkaiensis Ohwi in that its achenes are constricted in the middle part. However, C. foraminata is distinguished from C. brevispicula and C. chungii by its pistillate scale apexes, which are acute or shortly awned and by its achene apexes, which are shortly cylindrical; C. foraminata is distinguished from C. genkaiensis by its pistillate scale and achene shape. A precise description, illustration, photographs, and a key to related taxa are provided.

A newly recorded species, Boehmeria nakashimae Yahara, is confirmed for the first time to be distributed on forest edges on Jejudo Island, Korea. This species is known to be endemic to northern Kyushu, Japan. It is characterized by ovate to broadly ovate, elliptic-ovate, or sub-orbicular middle leaf shapes, serrulate-dentate and uniform margins, 17-29 teeth on one side, a short caudate or narrowly acute apex, dense glomerules at fruiting, and densely strigillose on the stems, both surfaces of the leaves, the perianth of staminate flowers, and achenes. Therefore, it is given the new name 'Je-ju-top-mo-si-pul' in Korean based on its serrulate-dentate leaf margin and geographical distribution. A description, photographs, illustrations, and keys of related taxa in Korea are provided.

Ipomoea heptaphylla Sweet and Murdannia nudiflora (L.) Brenan have been discovered on arable land on Jejudo Island, Korea. Ipomoea heptaphylla can easily be distinguished from other Korean Ipomoea species by certain distinctive features, which include thin and coiled long pedicels, small corollas, and, most importantly, palmatisect leaves with five to seven lobes. Murdannia nudiflora is characterized by the absence of a rhizome, the presence of caducous bracteoles, by its bearing of more than one flower, and by its fruits with two seeds per valve and foveolate-reticulate seeds, distinguishing it from M. keisak. In this study, we report the plants I. heptaphylla and M. nudiflora and provide their morphological descriptions, photographs, distribution, and keys.

The genus Grapholita Treitschke, belonging to the tribe Grapholitini, comprises over 150 species worldwide with the majority occurring in the Holarctic region. However, in other regions, only few species are reported owing to a lack of collection and taxonomic study. The genus includes important agricultural pests worldwide that feed on several plants in the families Fabaceae and Rosaceae. In Korea, a comprehensive taxonomic study is required as only eight species have been reported to date. In this study, two species of Grapholita Treitschke, G. latericia Komai, 1999 and G. pallifrontana (Lienig & Zeller, 1846) are newly recorded from Korea. We provide redescribed and illustrated adult and available genitalia. Additionally, all available information, including collecting localities, distribution, host plants and biological characteristics is presented.

Three species of seed beetles, Acanthoscelides pallidipennis (Motschulsky, 1874), Bruchidius terrenus (Sharp, 1886), and Kytorhinus senilis Solsky, 1869, from South Korea are reported for the first time. These three species can be morphologically distinguished from other Korean bruchid species by the distinctive color pattern of the elytra, presence of subapical spines on hind femur, and exposed last three tergites of abdomen, respectively. In this study, partial sequences of mitochondrial cytochrome c oxidase subunit I from Korean specimens of these species were generated. In addition, host plants, distribution maps, and photographs of the dorsal habitus and live specimens of each species are also included.
