A chaetiliid isopod, Symmius caudatus Richardson, 1904 is newly recorded from Korea with detailed description and illustrations. This species is characterized by the following features: head has well-defined ocular lobes anteriorly projecting; all pereonites do not have any projections dorsally; maxillule has 2 long plumose and 1 short denticulate setae on inner lobe; propodus of pereopod 1 has 11 stout circumplumose setae on ventral margin in female; and pereopod 7 is ambulatory. In this paper, we present the descriptions and illustrations of mature and juvenile males, which have not been known from previous studies, as well as those of female. We also suggested a revised diagnosis of the genus Symmius.

In 2017, small, elliptical, brownish purple spots on spears and ferns of asparagus were found in fields of Gangwon-do. The isolated fungal species was identified as an ascomycete Stemphylium vesicarium based on morphological characteristics and molecular phylogenic analyses including nucleotide sequences of the internal transcribed spacer (ITS), glyceraldehyde-3-phosphate dehydrogenase (GAPDH), and cytochrome b (cytb). A pathogenicity test revealed that S. vesicarium was the causal agent of purple spot disease on asparagus. The occurrence of purple spots caused by S. vesicarium on asparagus is the first report in Korea.

In this study, we aimed to observe the diversity of aquatic fungi by collecting deposits of soil, plants, and plant litter from streams and rivers. Three Penicillium strains were isolated from soil in streams. Based on the morphological characteristics and phylogenetic analysis using DNA sequences of the internal transcribed spacer, β-tubulin and calmodulin genes, the isolates were identified as Penicillium guanacastense, P. saturniforme, and P. scabrosum. These three fungi have not yet been reported in Korea.

The seven unrecorded ciliates were collected from soil samples in Korea. The morphological study of these ciliates was performed based on observation of both living and stained cells: Rigidocortex quadrinucleatus Bharti, Kumar and La Terza, 2017, Rigidohymena tetracirrata (Gellért, 1942) Berger, 2011, Urosoma salmastra (Dragesco and Dragesco-Kernéis, 1986) Berger, 1999, Urosomoida agilis (Engelmann, 1862) Foissner, 1982, Rigidosticha italiensis Bharti, Kumar and La Terza, 2016, Eschaneustyla terricola Foissner, 1982 and Pseudokeronopsis similis (Stokes, 1886) Borror and Wicklow, 1983. Among the seven genera in this study, the genus Rigidosticha Bharti, Kumar and La Terza, 2016 is firstly reported in Korea. In this study, we provide brief descriptions and remarks for the ciliates with photographs.

The common rough woodlouse Porcellio scaber Latreille, 1804 is newly reported from South Korea with following diagnostic characteristics: the presence of distinct tubercles on body; the strongly developed lateral lobes of head; the presence of notch on tracheal field of pleopod 1 exopod; and distinctly short exopod of uropod. This species is reported to be cosmopolitan, but there were no taxonomic records of it in South Korea. All voucher specimens were collected from humid shaded areas adjacent to the eastern coast of South Korea. Organismal ecology and scanning electron microscope photographs are provided. In addition, the results of CO1 analysis of individuals representing the different color and morphological variations are provided.

A eunicid polychaete, Marphysa victori Lavesque, Daffe, Bonifácio & Hutchings, 2017 is described for the first time from the intertidal zones of the Korean coasts. It is characterized by having three types of pectinate chaetae (INS, isodont-narrow-slender; AWS, anodont-wide-slender; and AWT, anodont-wide-thick), appearance of pectinate chaetae from chaetiger 2, the chaetae consisted of pectinate and compound spinigers, and pygidium with one pair of pygidial cirri. In genetic analysis based on cytochrome c oxidase subunit I (COI), intra-specific genetic distance between the specimens of M. victori from its type locality, France and Korea are in the range of 0.000-0.013. This paper includes the morphological description and photographs of M. victori new to Korean fauna, with partial sequences of the mitochondrial COI as DNA barcode data on this species.

Saxifraga cortusifolia Siebold & Zucc. (Saxifragaceae, sect. Irregulares, ser. Rufescentes), a species considered endemic along mountain streams throughout Honshu, Shikoku, and Kyushu in Japan, was discovered as a wild population in the Cheona Valley in Haean-dong, Jeju-si on Jeju-do Island of Korea. The population consisted of three subpopulations occupying narrow areas 10 × 10 m², 5 × 5 m², and 10 × 5 m² in size. The number of individuals in the three subpopulations was confirmed to exceed 100. Most of the individuals were on or below rocks at the edge of the valley. A morphological description, detailed photos, and a key to related taxa in Korea are presented.

Some sea urchins were collected from the subtidal rocky bottom along the coastal line in Jeju Island by SCUBA diving in April 2005 and identified on the basis of their morphological characteristics. Among them, Asthenosoma ijimai Yochiwara, 1897 was newly recorded from Korea and redescribed based on the specimen collected at 20m deep in southern breakwater of Seogwipo harbor. The order Echinothurioida including family Echinothuriidae and genus Asthenosoma was firstly recorded in Korea. Seventeen species of echinoids are reported to be distributed in Jeju Island of Korea.
