Two pelagic thaliacean tunicates, Pyrosoma atlanticum and Cyclosalpa quadriluminis, with bioluminescent organ, were collected from Jejudo Island and Korea Strait. In this study, the Pyrosomatida, which is holoplanktonic colonial tunicate with ascidiozooids embedded in a common test, and to which P. atlanticum belongs, is reported for the first time in Korea. The Cyclosalpa in the Salpida has a bar-shaped alimentary canal beside the branchial bar in both oozooids and blastozooids. Cyclosalpa quadriluminis is added to make Cyclosalpa species in Korea from four to five (C. affinis, C. bakeri, C. polae, C. sewelli, and C. quadriluminis). As a result of this study, 27 species of thaliaceans have been reported from Korea.

The genus Parornix Spuler, 1910 is a small group within the subfamily Parornichinae belonging to the family Gracillariidae in Korea. The subfamily Parornichinae was recently established as a taxonomic category by Kawahara & Ohshima, 2017, based on the largest dataset in a phylogenetic study. In this study, we reviewed the Korean species of the genus Parornix. In total, 5 species were recognized from Korea. Among them, one species, Parornix loganella (Stainton, 1848) is recorded for the first time from Korea. Descriptions and illustrations of the adults and genitalia of them are provided herein.

Two colonial ascidians, Eudistoma glaucum and Eudistoma purpureum, are reported for the first time in Korean waters through taxonomic study on ascidians collected from a subtidal zone of Jejudo Island. Eudistoma glaucum is distinguished by opaque green color of colony in living, massive colony with large corona, smooth surface of corona, sparse sand only at the peduncle, zooids in circle, about 8-10 stigmata of 3 stigmata rows and test process. Eudistoma purpureum is distinguished by brilliant, opaque, purple color of colony in living, less lobed colony form, smooth shiny surface, sparse sand only at the basal test, absence of symbionts, zooids in circle, no distinct bulging sphincter in siphon, long atrial siphon and about 20 stigmata of 3 stigmata rows. As a result of this study, four species of the genus Eudistoma are now recorded in Korean fauna.

Guest guidance system based on the compact battery-less information terminal, Aimulet, which has been developed by the authors of the National Institute of Advanced Industrial Science and Technology (AIST), Japan. Conventional Aimulet, which is Aimulet ver.1 or CoBIT, has features of location and direction sensitive information service device without batteries. On the other hand, the Aimulet has two subjects, one is multiplex and demultiplex of some contents, and the other is operation under sunshine. Former subject is of solved by the wavelength multiplex technique using LED emitter with different wavelength and dielectric optical filters. Latter subject is solved by new micro spherical solar cells with a visible-light-eliminating optical filter and a new design of light irradiation. These techniques are applied to the EXPO 2005, Aichi Japan and introduced in public. Aimulet GH is Former technique is applied on Aimulet GH, which is used in Orange Hall of the Global House, scientific museum with a fossil of a frozen mammoth.

Phylogenetic studies would clarify the diversity of fishes if the morphological analysis based on plesimorphy characters combined with new genetic analysis on molecular level, inferring more accurate and objective phylogeny and the taxonomy. Current molecular phylogenetic approach using mitochondrial genome provides the framework for a new hypothesis not only inferring the relationships between ancestor descendants but raveling the intra-, interspecies variation.

The Vietnamese occurrence of Stephania subpeltata H. S. Lo (Menispermaceae) is reported here for the first time. It is morphologically allied to S. japonica but differs in having subpeltate, ovate deltoid or broadly deltoid to subdeltoid leaves, shorter petiole, fewer leaf veins, conspicuously pedicellate umbelliform cymes which are seldom compound, and purple flowers and endocarp with a reduced number of abaxial rows. A taxonomic description, distribution details, ecology, and a key to the Vietnamese species of Stephania are provided.

Arthonia dokdoensis sp. nov., a lichenicolous fungus from the subcosmopolitan Arthonia molendoi complex growing on crustose thalli of species of the genus Orientophila (subfamily Xanthorioideae, Teloschistaceae), as well as the lichen species Rufoplaca toktoana sp. nov. (subfamily Caloplacoideae, Teloschistaceae) similar to Rufoplaca kaernefeltiana, both from Dokdo Islands, Republic of Korea, are described, illustrated, and compared with closely related taxa. In the phylogenetic tree of the Arthoniaceae based on 12S mtSSU and RPB2 gene sequences, the phylogenetic position of the A. dokdoensis and the relationship with the A. molendoi group are illustrated, while the position of the newly described R. toktoana is confirmed by phylogenetic tree based on ITS nrDNA data.

Two new species of Clausidiidae, each belonging to the genera Clausidium Kossmann, 1875 and Hippomolgus G. O. Sars, 1917, are described from Korea. Clausidium maximus n. sp. is an associate of a burrowing decapod of the genus Callianassa living on the Korean coast of the Yellow Sea and has, as diagnostic characters, two inner setae on the second endopodal segment of legs 2-4, nine elements on the third exopodal segment of leg 4, an inner seta on the second exopodal segment of male leg 1, and a relatively large body size, exceeding 2.0 mm in the female. Hippomolgus limiticus n. sp. was found in the bottom sediments in the East China Sea. It is similar to H. furcifer G. O. Sars, but distinghuishable from the latter species by having shorter caudal rami, 4-segmented female maxilliped, and inner coxal spine (instead of seta) on legs 2 and 3. This is the first record on the genera Clausidium and Hippomolgus in the West Pacific.
