Fifteen species of water mites belonging to the genus Atums are reported from the eastern area of Korea, with the following five of them described as new species: Aturus glaberus, A. parauarus, A. quodrotus, A. sankveriensis, and A. trifurcatus, n. sap. A. complexus Sokolow and A. tewaconfusensis Habeeb, both new records for Korean fauna, are re-described.

One Iravadiid shell Iravadia (Fluviocingula) elegantula (A. Adams, 1861), from the brackish waters in Kangwon-do was recorded as new to the Korean molluscan fauna. The shell is typically solid and narrowely ovate-conic. The protoconch is small, planorboid to depressed dome-shaped, typically with a minute first whorl. Including the new records in this study, the family Iravadiidae contained 2 genera and 3 species in the Korean water.

Three species of the family Biphyllidae - Biphyllus japonicus Sasaji, 1983, Biphyllus loochooanus Sasaji, 1991 and Biphyllus oshimanus Nakane, 1988 - are reported for the first time in Korea. Descriptions, photographs of the adults and line drawings of the diagnostic characters are provided for all the species recognized in this study.

Two new records of spionid polychaetes, Prionospio pulchra Imajima, 1990 and Scolelepis (Scolelepis) sagittaria Imajima, 1992, collected from Korean waters are reported here with detailed descriptions and illustrations. Prionospio pulchra can be distinguished from its relatives by remarkably long and apinnate branchiae, the first chaetiger with notopodial chaetae, and the presence of ventral sabre chaetae. Scolelepis (Scolelepis) sagittaria is characterized by a sagittate prostomium, an occipital tentacle, and bi- or tridentate hooded hooks. In this paper, photographs of scanning electron microscopy for characteristic features of each species are presented. Keys to Prionospio and Scolelepis species from Korean waters are also provided.

Two new records of scolecid polychaetes, Praxillella pacifica Berkeley, 1929 and Naineris dendritica (Kinberg, 1867), collected from Korean waters are reported here with descriptions and illustrations. Praxillella pacifica can be distinguished from its congeners by the number of asetigerous segments on the posterior region of the body and features of the anal cone and neuropodial spines on setigers 2 and 3. Naineris dendritica is distinguishable from its relatives by the morphology of thoracic neuropodial lobes and the thoracic uncini at the inferior position. In the present paper, keys to Praxillella and Naineris species from Korean waters were also provided.

Aquatic oligochaetes were investigated from a small amount of sediment sampled from the Jungnang Stream, an urban stream in Seoul, Korea, in November 2012. Sorted oligochaetes were observed under a light microscope in a drop of carbonated water, and then preserved in 70% ethanol. Some specimens were slide mounted using glycerin and Eupharal. As a result, the following 12 species were identified including 8 new Korean records, Bothrioneurum vejdoskyanum Stolc, Branchiodrilus hortensis (Stephenson), Chaetogaster cristalinus Vejdosky, Nais communis Piguet, Nais pardalis Piguet, Dero obtusa d'Udekem, Piguetiella denticulata Liang, and Haemonais waldvogeli Brescher and 4 additional known species, Limnodrilus hoffmeisteri Cleparede, Branchiura sowerbyi Beddard, Chaetogaster diastrophus (Gruithuisen), and Stylaria fossularis Leidy. This study shows how freshwater oligochaetes are diverse even in urban streams in Korea, if a proper sampling and examining method is employed.

Two monstrilloid copepod species belonging to the genus Monstrilla Dana are newly recorded from Korea: M. grandis Giesbrecht, 1891 and M. hamatapex Grygier and Ohtsuka, 1995. Specimens were obtained from inshore waters around the coasts of South Korea, using a light trap installed at quays and wharves overnight. Based on the Korean specimens, the two species are redescribed, with brief accounts of their affinities and morphological variabilities. Remarkable morphological discrepancies are confirmed in female leg 5 of M. grandis between type material from Southern Hemisphere and European and Asian specimens, which raise a strong doubt on their conspecificity. Korean specimens of M. hamatapex well coincide with the type specimens from Japan, except for some variations in the setal armature of leg 5 and antennules. This is the second taxonomic paper on the monstrilloid copepods in Korea, and the genus Monstrilla is newly added to Korean fauna.

Collema Weber ex F.H. Wigg is scarcely scattered throughout South Korea. However, a detailed taxonomic or revisionary study has not been carried out for almost two decades. The present study was based on specimens deposited in the lichen herbarium at Korean Lichen Research Institute, which were identified using recent literature. In this revisionary study, a total of sixteen species of Collema, including five new records, C. furfuraceum var. luzonense, C. pulchellum var. subnigrescens, C. rugosum, C. subconveniens, C. tenax, and one variety C. leptaleum var. leptaleum were documented. Further, detailed descriptions of each species and their morphological, anatomical and chemical characteristics and a key to all known Collema species of South Korea were reported.

South Korean species of the genus Teleutaea is taxonomically studied. This genus is recorded from South Korea for the first time with eight species, Teleutaea acarinata, T. brischkei, T. diminuta, T. minamikawai, T. mishae, T. nigra, T. orientalis and T. ussuriensis. A key to eight South Korean species of Teleutaea and digital images are provided.
