A survey of insect fauna on Dokdo Island was conducted by Yeungnam University from 2009 to 2016. The survey locations were the two islands of Dokdo Island (i.e., East and West Islands), located in the East Sea of South Korea. As a result of the survey, we identified five orders, 20 families and 27 species including 10 species newly recorded on Dokdo Island, of which Eupelmus australiensis (Girault) is recorded for the first time in South Korea. In combination with the results of previous surveys made from 1981 to 2016, the insect fauna of Dokdo Island is now known to consist of 10 orders, 77 families and 164 species (and 29 additional undetermined species). In this paper, we list the insect fauna on Dokdo Island and present photographs of 10 species with brief taxonomic notes of a eupelmid species.

Two Entoloma species, E. eugenei and E. subaraneosum, are described here as newly recorded species in Korea. These two species were recently described from far Eastern Asia, Primorsky Territory of Russia, and Jilin province of China, respectively. Here, these species were reported based on internal transcribed spacer and partial large subunit of ribosomal RNA sequences, and macro- and micro-scopic characteristics for the first time in Korea.

Lovenia elongata is a member of the family Loveniidae and is one of the most common tropical echinoids. This species has a broad distribution range in the sub- and tropical regions of the Indo-Pacific Ocean, extending from the Mozambique to the Hawaiian Islands, and from southern Japan to northern Australia. It is commonly found in subtidal areas and on coral reefs within these regions. This species was for the first time recorded from the Ulleungdo Island, Korea. This species is characterized by a teardrop-shaped test that reaches up to 5 cm in length, with a deep groove at the front and tapered at the back end. The petaloid is not obvious, and the primary spines are long and banded. This study is the first to report the newly recorded L. elongata in Korea.

Mt. Taebaeksan extends from Gangwon-do Province (Taebaek-si, Youngwon-gu, and Jeongseon-gun) to Gyeongsangbuk-do Province (Bongwha-gun), South Korea. Indigenous fungi present in the park were investigated between 2019 and 2022. All collected specimens were identified to the species level based on their morphological characteristics and molecular phylogenetic analysis using sequences from the internal transcribed spacer (ITS) and large subunit (LSU) of ribosomal DNA. Among them, 17 species-Cyanosporus bifarius, Dacryobolus angiospermarum, Entoloma sericeum, Flammulina rossica, Fuscopostia leucomallella, Homophron helvolescens, Hygrophorus queletii, Hymenochaete huangshanensis, Inocybe albodiscoides, Lactarius fulvihirtipes, Lepiota ignivolvata, Physisporinus eminens, Ramaria gracilis, Russula albolutea, Russula cremicolor, Stropharia lignicola, and Tengioboletus subglutinosus-were newly recorded macromycota in Korea.

To find unrecorded diatom species in the Nakdong River Estuary and Yeongil Bay, bottom sediments in the estuary, and seagrasses in the bay were collected from 12 sampling sites. Eighteen species and four genera are added to the national flora of diatom as newly recorded one. In the Nakdong River Estuary, twelve species are new records to Korea, Martyana atomus (Hustedt) Snoeijs, Pseudostaurosira perminuta (Grunow) Sabbe & Vyverman, Trachysphenia acuminata M. Peragallo, Trachysphenia australis Petit, Fallacia clipeiformis ($K{\ddot{o}}nig$) D.G. Mann, Amphora graeffeana Hendey, Amphora jostesorum Witkowski, Metzeltin & Lange-Bertalot, Amphora ostrearia var. vitrea (Cleve) Cleve, Amphora wisei (Salah) Simonsen, Halamphora eunotia (Cleve) Levkov, Halamphora lineata (Gregory) Levkov, Nitzschia littorea Grunow. In Yeongil Bay, four species are added as new, Licmophora gracilis var. anglica ($K{\ddot{u}}tzing$) H. Peragallo & M. Peragallo, Tabularia investiens (W. Smith) Williams & Round, Nitzschia composita Giffen, Nagumoea neritica Witkowski & Kociolek. Two species occurred simultaneously in both regions, Fragilaria cassubica Witkowski & Lange-Bertalot and Hyalinella lateripunctata Witkowski et al.

Four species of the genus Exochus belonging to the subfamily Metopiinae, family Ichneumonidae, are reported in South Korea for the first time. The subfamily Metopiinae was recorded by Förster in 1869 based on genus Metopius and more than 870 described species have been reported worldwide. Among the genera of Metopiinae, genus Exochus is the largest, which is cosmopolitan and comprises more than 290 described species worldwide (Choi et al., 2016; Yu et al., 2016). A taxonomic study of South Korean Exochus was initiated by Choi et al. (2014), who reported four species. Until now, 10 species have been described as new species and 25 species were recorded as new records of this genus from South Korea (Choi et al., 2014, 2016). In the present study, the following four species are reported in South Korea: Exochus latiareolus Tolkanitz, 2003, E. ornatus Momoi & Kusigemati, 1970, E. pictus Holmgren, 1858, and E. yasumatsui Momoi, Kusigemati & Nakanishi, 1968. In addition, we provide the diagnoses of these four species along with diagnostic photographs.

Rhyssemus Mulsant, 1842, represents one of the largest genera in the tribe Psammodiini, comprising approximately 170 species to date. This group is nearly cosmopolitan, excluding the Neotropical region, with 59 species recorded in the Palearctic region. On the Korean Peninsula, only one species, Rhyssemus koreanus Stebnicka, 1980 was recorded from North Korea. In this study, the genus Rhyssemus is recorded for the first time with a newly recorded species Rhyssemus inscitus (Walker, 1858) from South Korea. Adult specimens were collected from the costal sand dunes in Taean-gun and Jeju island. We herein provide a diagnosis, illustrations of morphological characters, and habitat information. Partial mitochondrial COI sequences of the species are also provided for DNA barcoding.

The species Socarnes bidenticulatus japonicus Gurjanova, 1962 belonging to the family Lysianassidae Dana, 1849 has been collected from Namae, on the east coast of Korea. The genus Socarnes Boeck, 1871 has 12 species worldwide. However, only one Socarnes species had been reported in Korea until now: S. tongyeongensis Kim & Hendrycks, 2013. This genus is characterized by a longer article 2 of mandibular palp, unconstructed inner ramus of uropod 2, biarticulated outer ramus of uropod 3, and deeply cleft telson. A newly recorded species S. bidenticulatus japonicus is characterized by a posteriorly bidentated epimeron 3 and constricted inner ramus of uropod 2. The species is described and fully illustrated in this study.

Araeosoma owstoni Mortensen, 1904, a newly recorded sea urchin, was collected from the Korea Strait by trawling during a research expedition in April 2017. The specimen was damaged and was severely peeled off on the aboral side during trawling. However, a test and the surface of the oral side of the sample were well preserved, allowing us to successfully identify it. The species was distinguished by the large and flexible test, the tiny apical section, and the interambulacra width which is twice of the ambulacra. Pedicellaria tridentate and triphyllous were presents, but tetradactyle pedicellaria was absent due to severe peeling on the aboral side. Moreover, a length of 1,212 bp sequence from mitochondrial COI gene was obtained and this sequence covered the general DNA barcoding region. The mean of interspecific divergence within A. owstoni from Korea and other eight species of Araeosoma from the GenBank was 6.8%. This value indicated that our species was clearly distinguishable from the others. Thus, the first Araeosoma species occurring in South Korea is presented in this study.
