Netelia Gray, 1860, a largest genus within the subfamily Tryphoninae and its distribution is worldwide. The members of Netelia are known to be ectoparastic koinobionts of lepidopteran larvae. More than 330 species have so far been recorded and divided into 12 subgenera. Among them, the subgenus Amebachia Uchida, 1928 was reported as a genus by Uchida (1928) based on Amebachia baibarana from Taiwan. The lectotype of Amebachia baibarana Uchida, 1928, was re-examined and then this species should be a subgenus of the genus Netelia by Konishi (2010). Consequently, five currently valid species of Netelia (Amebachia) have been described in the world. As a result of the present study, the subgenus Amebachia belonging to the genus Netelia is reported from South Korea for the first time based on a species of Netelia (Amebachia) rasilella and N. (A.) yoshimatsui. Redescriptions and photographs of the diagnostic characters of two species are provided. This research was supported by Basic Science Research Program through the National Research Foundation of Korea (NRF) funded by the Ministry of Education (NRF-2016R1A6A3A03007788).

The family Pteromalidae are one of the numerous and economically important groups of parasitoids, but our knowledge of this group in South Korea is limited. Up to date, only 39 species of 27 genera belonging to five subfamilies have been recorded from south Korea. This study is based on the material from the Applied Entomology Division, Department of Agricultural Biology, National Academy of Agricultural Science (NAAS) and Yeungnam University, Gyeongsan, South Korea (YNU). As a result of this study, four species (Diglochis sylvicola (Walker), Lariophagus obtusus Kamijo, Mokrzeckia lazoensis Tselikh, Paracarotomus cephalotes Ashmead,) in Pteromalinae are recorded for the first time in South Korea. Among them two genera (Diglochis Förster, Paracarotomus Ashmead,) recorded for the first time in South Korea. Therefore, 43 species of 29 genera in Pteromalidae are recorded from South Korea.

The subfamily Allantinae is one of the large subfamilies within the family Tenthredinidae with about 900 described species in the world. All of the species are worldwide distributed and 322 of them are from Eastern Palaearctic region. Also, in the neighboring countries, it has been recorded that 275 species in China, 90 species in Japan and 131 species in Russia. But only 15 species have been reported in South Korea. Generally subfamily Allantinae can be easily recognized from other subfamilies by the following characters in fore wing: Veins M and Rs+M meeting Sc+R at or very near the same point; vein 2A+3A complete, always separated from 1A by an anal crossvein; veins M and 1m-cu parallel; vein 2r present. Moreover, all larvae of Allantinae are phytophagous and external feeders on the foliage of the host. In this study, we report eight species belonging to the five genera (Allantus, Ametastegia, Apethymus, Asiemphytus and Taxonus) from South Korea for the first time. As a total of 11 genera and 24 species in Allantinae were identified to occur in South Korea. A key, diagnoses and photographs of the diagnostic characters are provided.

Some asteroid specimens were collected at a depth of 150 m near Moseulpo in Jeju Island, Korea using fishing nets on October 2014. The specimens were identified as Henricia pacifica Hayashi, 1940 belonging to the family Echinasteridae of order Spinulosida. In the Korean fauna, seven species of genus Henricia were reported of which two species, H. nipponica and H. ohshimai, were distributed in Jeju Island. The morphological characteristics of this species were re-described with illustrations.

In this study, a genus Eumasia Chrétien is reported for the first time from Korea. This study was conducted to report a newly recorded genus and species, Eumasia muscella Saigusa and Sugimoto based on the material from Haemee-castle, Seosan-si, Korea. All available information for the species including distributional ranges and host plants were presented in this study. Also the larval characteristics and DNA barcode for the species are provided.

A harpacticoid species, Paramphiascella fulvofasciata Rosenfield and Coull, 1974, belonging to Miraciidae Dana, 1846 is newly reported from Korean waters. The species is mostly related with P. pacifica Vervoort, 1962, however, it is easily distinguished by the typical structure of male P2 in having 1 large spine and 2 setae on P2 enp-2. Korean materials represented some discrepancies from the original description of P. fulvofasciata in the detailed structures of mouth parts. The present study is a first record of the genus Paramphiascella Lang, 1944 from Korean waters.

Some euryalid specimens were collected with fishing nets from Mipo, Gyungsangnamdo and Aewol, Jejudo Island, Korea. They were identified as Gorgonocephalus eucnemis (Müller & Troschel, 1842), belonging to family Gorgonocephalidae of order Euryalida, which was new to the Korean fauna. Their molecular analyses were done with newly intended COI primers of mitochondrial cytochrome oxidase I (COI) gene for the accurate molecular identification. The Korean G. eucnemis was coincident with this NCBI species as a result of Blast analysis, which showed the 99% similarity. In the current study, three Gorgonocephalus species have been reported from Korea.

Asteroid specimens were collected from Shinnam, Gangwondo in the East Sea of Korea with fishing nets on 12 September 2014. The specimens were identified as Henricia reticulata Hayashi, 1940, belonging to family Echinasteridea of order Spinulosida. This species can be distinguished by a larger disc and broader arms compared to those other Henricia species. The morphological characteristics of this species are re-described with illustrations. By previous work of this genus, six species have been reported in the Korean fauna.

Three marine heterotrophic flagellates from intertidal sediments of Gwang-Am beach and Garorim Bay, Korea were identified as Neometanema parovale Lee and Patterson 2014, Stephanopogon pattersoni Lee et al. 2014 and Thaumatomastix sp. These species are reported taxonomically for the first time from Korea, and are described with illustrations and micrographs. Diagnostics of these species are as follows. Neometanema parovale (Euglenozoa): size in vivo, 10~23 μm long with 22 pellicular strips, ingestion apparatus barely visible by light microscopy and two flagella pointed in different directions when moving. Stephanopogon pattersoni (Percolozoa): size in vivo, 20~33 μm long, with 6 ventral and 1 ventro-lateral ciliary rows, and three barbs. Thaumatomastix sp. (Cercozoa): size in vivo, 14~17 μm with body scales and spines, and two flagella with one naked and one scaled.

Amur silver grass, Miscanthus sacchariflorus is one of the promising biofuel crops. A damage of noctuid pest, Leucapamea askoldis was firstly observed from Amur silver grass in Hwasun silver grass plantation during the survey of insect pests of Amur silver grass in Iksan, Hwasun, and Sancheong plantation areas in Korea. The host of L. askoldis was not known yet in Korea. Thus, M. sacchariflorus was the first known host in Korea. The L. askoldis damage was observed as larval feeding on newly grown shoots of M. sacchariflorus close to soil surface from early April to early May in 2013. Investigated larval density was 1.6 ± 1.1 per m2 on April 4 and damage rate of shoots was 0.8% ± 0.4 per hundred plants on May 4, 2013. The larvae bore into shoots of M. sacchariflorus and then feed inside of plant. The damaged shoots are easily pulled out and distinguished by the boring hole on the shoots.

Nitidulid beetles of the genus Aethina Erichson, 1843 are a well-known group as harmful to agricultural and apicultural industry, especially including A. tumida, an American small hive beetle, which is a beekeeping pest. The world-widespread genus Aethina, within subfamily Nitidulinae and family Nitidulidae, is presented 5 subgenera and 28 species in Palaearctic region. Until now, 2 subgenera, Aethina s. str. and Aethina (Circopes), and 3 species, A. (A.) flavicollis, A. (A.) inconspicua and A. (C.) suturallis, have been recorded in Korea, and we added one more species, A. (A.) maculicollis as a newly recorded species. The larvae of A. (A.) maculicollis have been reported as pests of mulberry fruits in Japan. In this study, we report the taxonomic key to the genus Aethina of Korea, and morphological description of A. (A.) maculicollis.
