From an examination of caprellid specimens collected from Korea, we found a new species belonging to the genus Perotripus. This new species is clearly distinguished from two previously recorded species, P. brevis and P. keablei, in having an acute projection and blunt apex of distal segment of pereopod 5. This genus Perotripus is reported from Korea for the first time. We described it with figures in detail. As a result, Korean caprellid fauna consists of 35 species in seven genera.

A new genus Parkiana Cho, gen. nov., belonging to Torodorinae of Lecithoceridae, is described from Madagascar, with two new species: P. matutinalis Cho & Agassiz, sp. nov. and P. andasibensis Cho & Agassiz, sp. nov. Although superficially similar to Thubdora Park, 2018, some of their morphological characters, such as wing venation, are unique and the species of the genus are grouped apart from Thubdora in a preliminary phylogenetic analysis based on COI barcode sequences. In addition to the specific descriptions, adults and genitalia for the two new species are illustrated.

A new species, Monoblastus forsythia sp. nov. is described from South Korea. All specimens of this new species were collected on Forsythia koreana (Nakai). A taxonomic study of South Korean Monoblastus was initiated by Uchida in 1930, and until now four species have been recorded from South Korea. The genus Monoblastus is a Holarctic genus with 31 described species, 14 species are Nearctic, seven are Western Palaearctic region, and nine species occur in Eastern Palaearctic region. In the study, I provide description and photos of both sexes of this new species. Also, modified key to species of the South Korean Monoblastus is provided.

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.

A new species belonging to the genus Cyclopinoides Lindberg, 1953 (Cyclopinidae) is described from three beaches in Korea and Japan, as the first record of the genus from the Pacific. Among five species currently recognized in the genus, the new species resembles C. schulzi Herbst, 1964 from the Red Sea in sharing the character combination of 20-segmented antennule and stumpy caudal rami. However, C. orientalis n. sp. differs from it by relatively longer caudal rami (2.5-2.8 times as long as wide in female and about 1.6-1.8 times in male, while less than 2 times in female and about 1.3 times in male of C. schulzi), and by the transformation of an outer distal spine to a slender seta on the distal exopodal segment of leg 4. Moreover, C. orientalis n. sp. is discernible from C. schulzi in having a pyriform copulatory tube (against elongated tubular style in C. schulzi). A key to the species hitherto known in the genus is provided.

A new species of the genus Biemna(Demospongiae: Poecilosclerida: Desmacellidae), Biemna hongdoensis n. sp. was collected from Hongdo Island, Korea by SCUBA diving in 2004. B. hongdoensis n. sp. is closely related to B. megalosigma Hentshel, 1912 in their spicules, but the styles and sigmas of new species are larger than B. megalosigma's and microxeas and raphides of new species are smaller than B. megalosigma's. Also, new species has not spheres. The stubby conulose are distributed throughout the surface of new species.

Four new species of genus Scalarispongia (Demospongiae: Dictyoceratida: Thorectidae) are described from Jejudo Island, Korea. These new species of Scalarispongia are compared with 14 reported species of the genus by the skeletal structure. Scalarispongia songakensis n. sp. is similar to S. lenis in sponge shape but differs in skeletal structure and meshes are not divided into two sections. The length of secondary fibres between primary fibres of this new species is much longer than S. lenis'. Scalarispongia radicula n. sp. is resembles S. songakensis in sponge shape, but this new species has pseudo-tertiary fibres at the sponge base. Scalarispongia maraensis n. sp. is very similar to S. subjiensis in sponge shape but primary fibres of this new species are not simple because fibres have wide webbing. Scalarispongia massa n. sp. is characterized by the large mass sponge shape and numerous open oscules form a long ling on the ridge of the sponge.

In this study, we conduct a review of the genus Taeniogonalos Schulz, 1906, which belongs to the subfamily Trigonalinae (Hymenoptera: Trigonalidae) from Korea. The genus Taeniogonalos Schulz is recognized as a relatively small genus. Taeniogonalos comprises 53 described species worldwide, including nine species identified in the Eastern Palaearctic region. A total of four species have been recognized from Korea. This paper enumerates the known species in Korea, including the new record. We provide the diagnosis and photographs for the newly recorded species. Additionally, we present a key to the Korean species of Taeniogonalos Schulz, 1906.

Araneidae Clerck, 1757 is one of the largest families within the order Araneae Clerck, 1757, comprising 3,065 species in 177 genera. To date, two species of the genus Mengora O. Pickard-Cambridge, 1889 and four species of the genus Araniella Chamberlin & Ivie, 1942 have been recorded in Korea. During a seasonal survey of the spider fauna in mountainous terrain conducted from 2018 to 2019, females of Mangora foliosa Zhu & Yin, 1998 and a male of Araniella robusta sp. nov. were collected with a sweep net between shrubs in mixed forests from Mt. Juwangsan National Park. In this paper, we provide a diagnosis of the new species and descriptions including measurements and morphological illustrations. The new species, Araniella robusta sp. nov., can be easily distinguished from other species in the genus Araniella Chamberlin & Ivie, 1942 by a branched conductor with two blunt tips and conjugation of the embolus tip and terminal apophysis.
