As a part of the commemorative joint faunal survey for the 30th anniversary of the Korean Society of Systematic Zoology, the molluscan fauna of Jindo Island was investigated based on sample collection from 6 localities from the 6 to the 8 of Jul 2016. A total of 114 molluscan species from 47 families were collected and identified. Among these, 42 species from 11 families are newly reported from Jindo Island and combining the previous records with the present study totals 157 species from 57 families. Distribution of species records indicates that marine biogeography of Jindo Island represent an overlapping zone for marine organisms which dwell in the Yellow sea and the southern sea areas of Korean waters.

We surveyed the freshwater invertebrates of Jindo Island twice on July and September 2016, as part of a joint faunal survey conducted to commemorate the 30th anniversary of the Korean Society of Systematic Zoology. Aquatic insects were not included in this study. We found 38 freshwater species from seven phyla: Porifera, Platyhelminthes, Nematomorpha, Mollusca, Annelida, Arthropoda, and Bryozoa. Twenty-one of the 38 species (55.3%) represented the first record of their respective species on Jindo Island. Among these species, a freshwater shrimp-parasitic isopod, Tachaea n. sp., was identified as a new species.

Adult caddisflies were collected from 11 sites in Cheongdo-gun (Gyeongsangbuk-do) and Miryang-si (Gyeongsangnam-do) in the southeastern part of the Korean Peninsula. Collections on August 28 to 30, 2015, by aerial sweeping and light trapping, included one new species and four newly recorded species from the Korean Peninsula. Description of the new species Paduniella unmun Inaba and Park (Psychomyiidae), and re-description of the four species (Polyplectropus malickyi Nozaki et al., 2010, Tinodes furcatus Li and Morse, 1997, Cheumatopsyche tanidai $Ol{\acute{a}}h$ and Johanson, 2008, and Diplectrona kibuneana Tsuda, 1940) are provided. Additionally, we recognize that a larva described as Diplectrona KUa is the larval stage of D. kibuneana.

Two marine gastrotrich species of the genus Acanthodasys, A. ericinus Lee, 2012 and A. comtus Lee, 2012, are taxonomically reconsidered. Both of them were originally described based on the specimens from intertidal or sublittoral sandy bottom of the Yellow Sea and Jeju Island, South Korea, and included in a monographical publication of in 2012. However, the description of them was quite insufficient, and designations of type specimens were entirely lacking. In this study, we make a subsequent designation of type specimens for the two Acanthodasys species, and carry out a full redescription of them with additional remarks on their morphological micro-characteristics by scanning electronic microscopy. Some brief nomenclatural notes on Korean marine gastrotrichs are also provided.

The present census on freshwater bryozoans in the Han River, Geum River and in lentic water bodies in Gangwon Province revealed three gymnolaemate species. Two of them-Hislopia prolixa Hirose and Mawatari, 2011 and Victorella pavida Saville Kent, 1870 were recorded for the first time from South Korea. Paludicella articulata (Ehrenberg, 1831), on the other hand, had already been documented from a few sites since 1941. The bryozoans, all belonging to the order of Ctenostomata, were found on a variety of substrates in freshwater (H. prolixa and P. articulata) and brackish habitats (V. pavida). Hislopia prolixa had recently been established as a new species and this is the first record for an occurrence outside of Japan, where it had been newly described from Lake Biwa and nearby satellite lakes.

A halacarid species of Scaptognathus teuriensis $Ab{\acute{e}}$ is recorded from Korea on the basis of the specimens collected from littoral sandy sediments at Dokdo Island, the easternmost island off Uleung Island of South Korea. Korean specimens coincide well with the key characters in the original description for types from Hokkaido, Japan, such as male genitoanal plate comprising only pars sclerosum, bipartite female genitoanal plate with six perigenital setae, rounded posterior margin of anterior dorsal plate, second and fifth dorsal setae both positioned at membranous cuticle, leg chaetotaxy of bipectinate setae on tibiae I-IV of 4-2-2-2, and tarsi of all legs armed with paired large lateral claws with accessary teeth and small median claw. Redescription based on Korean specimens and scanning electron microscope photomicrographs are provided herein. This is the first record of the genus from Korea.

The continuous taxonomic study on decapods from Korean waters revealed that the alpheid shrimps collected from Jejudo Island and Busan were identified as a species belonging to the genus Arete which is an unreported genus from Korean waters. The genus Arete can be distinguished from the most similar genus Athanas by the following. The chelae are broad and oval-shaped in Arete, but in Athanas, the chelae are more or less elongated. The number of carpal segments in the 2nd pereopod is four but five, exceptionally four or six in Athanas. The epipods are present on pereopod 1 and pereopod 2 in Arete, but on pereopod 1-3, exceptionally on pereopod 1 and pereopod 2 or pereopod 1-4 in Athanas. In this paper, Arete dorsalis is reported for the first time from Korean waters. Korean Alpheidae fauna now consists of 27 species of nine genera.

The family Psychidae is a small group consisting of 241 genera and 1,350 species in the world. The genus Bacotia, belonging to the family Psychidae, what was established by Tutt based on the type species, Fumea sepium Speyer and Speyer, 1846. In this study, we aimed to record lichen-feeding bagworms in Korea. The genus Bacotia Tutt is reported for the first time from Korea with one newly recorded species, Bacotia sakabei Seino, 1981. All available information, including the collecting localities, host plants, illustrations of adults and genitalia are presented. A DNA barcode for precise identification of the species is also described.

The external anatomy of the immature stages (last instar larva and pupa) of the crane fly, Tipula (Nippotipula) sinica Alexander, 1935 (Diptera: Tipulidae) is described and illustrated from specimens first collected in Korean peninsula (South Korea). Comments concerning natural history and microhabitats of larvae are provided. This is the first detailed description with illustrations for the last instar larva and pupa of Tipula (Nippotipula) sinica. Pupal characteristics resemble those of most species from advanced lineages within the subfamily Tipulinae. And, also it described with habitats and biological notes of Tipula (Nippotipula) sinica. Crane fly larvae, categorization as found in this survey indicate a taxonomic stream and are expected to help.

A hyalid amphipod, Protohyale pumila (Hiwatari and Kajihara, 1981), collected from Jeju Island is reported for the first time in the Korean fauna. The species is characterized by the presence of a short apical spine on the palp article 4 of maxilliped, a distinctly large and blunt cusp on the propodus of male gnathopod 1, and a distal truncate process on the palm of male gnathopod 2. Herein, the present species is described and illustrated. Korean hyalid amphipods now are composed of four species belonging to three genera. Voucher specimens were deposited in the Marine Arthropod Depository Bank of Korea, Seoul National University.
