Two species of mantid shrimps were collected from southern part of Korea and identified as Kempella mikado and Squilloides leptosquilla of the Squillidae. The former species is characterized by having a dactylus of the raptorial claw with six teeth, only the fifth thoracic somite with a single spinous lateral process, and the fifth abdominal somite with a pair of black dorsal patches. However, the latter species is characterized by having a dactylus of the raptorial claw with four teeth, and the fifth to seventh thoracic somites each with a single lateral process. Both species are described with figures and photographs. The present records are extensions of their geographical distributions and new records in Korea. Hence, a total of six species of the stomatopods have been recorded in Korea up to date: Oratosquilla oratoria, Faughnia formosae, Taku spinosocarinatus, Chorisquilla spinosissima, Kempella mikado, and Squilloides leptosquilla.

The scyllarine lobster Chelarctus cultrifer is described as the first species of the genus Chelarctus known from Korean waters. C. cultrifer is very similar to the Galearctus kitanoviriosus but it is different in the pleura of the abdominal somites 2 to 4 are broader and ending in sharp posteriorly directed points and having the propodi of pereiopods 3 and 4 are forming subchelates with the dactyli. The record of the species represents an extension of its previously known range from Somalia to Hawaiian Islands and brings the number of known species of the scyllarine lobsters in Korea to three.

The larvae of Oregonia gracilis are described, illustrated and compared with those of other known species of the Oregoniidae. The first zoea of O. gracilis of the present study is somewhat different from that of Hart (1960) especially in having a basis and an endopod of the first maxilliped with 2, 2, 3, 3 and 3, 2, 1, 2, 5 setations, respectively and an endopod of the second maxilliped with 1, 1, 5 setation. It is found the Oregoniidae must be a homogeneous group based on the zoeal morphology. A provisional key for the identification of the known zoeae of the Oregoniidae from the northern Pacific is provided.

Pagurus undosus and Pagurus parvispina, collected from the East Sea by fishery trap, are newly recorded from Korean waters. Pagurus undosus is distinguished from other hermit crab by its right cheliped slightly elevated medially, and with broad ridge formed by deep depressions mesial and lateral to midline. Pagurus parvispina is distinguished from other hermit crab by its right cheliped covered with large spine and long tufts of setae. These species live in cold water areas and their geographical distribution is extended southwardly by the present study. A specimen of the former species, P. undosus, was found living in a shelter formed by a sponge, similar to that observed in Pagurus pectinatus. Descriptions and figures of these two species are provided in this paper. Currently, 27 species of the genus Pagurus are recorded in Korean fauna.

As a result of continuous taxonomic investigations of Korean crabs, Pugettia intermedia Sakai, 1938 is newly reported from Korean waters. Pugettia intermedia had previously been reported in Korean fauna, but the previous reports of P. intermedia were resulted in misidentification of P. quadridens (De Haan, 1839). Pugettia intermedia differs from P. quadridens in having two subequal medial lobes of the first pleopod in male. In P. quadridens, one of the two medial lobes is about half-length of the other. Pugettia intermedia occurs on the southern coast of the Korean peninsula. The descriptions and illustrations of this species are provided herein.

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.

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.

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.
