  • A new species of leuconid cumaceans, Nippoleucon projectus n. sp. is described on the basis of the specimens collected from western shallow coast of the South Korea. This new species is easily distinguished from two previously recorded species (N. hinumensis and N. enoshimensis) in having the fifth abdominal segment prominently projected to rear at dorsal posterior portion and the carapace of the female with three spines on the frontal lobe.

  • Coccoid green algae collected from March to November 2015 from 79 freshwater ecosystem sites throughout South Korea, including lakes, ponds, swamps, streams, and rivers, were identified using light microscopy. A total of 218 taxa were identified, among which 11 were new species records in Korea; these 11 species were found at four sites (Hanagang River, Chukdong reservoir, Chukdong fishery, and Deokjin reservoir). The new species recorded were Fotterella tetrachlorelloides, Trochiscia naumannii, Keriochlamys styriaca, Placosphaera opaca, Siderocystopsis fusca, Siderocelis oblonga, Siderocelis estheriana, Pachycladella umbrina, Pachycladella zatoriensis, Crucigenia mucronata and Scenedesmus sempervirens.

  • A new species of bryozoan, Bicellariella fragilis n. sp. is reported from Jejudo Island, Korea. It was collected at Munseom I. and Supseom I. off Seogwipo city by the fishing net and SCUBA diving from 1978 to 2009. The new species has characteristics of four to five dorso-distal spines and two proximal spines, whereas ten to twelve spines of B. sinica are not separated into two groups of the distal and proximal ones. And this species shows the difference from B. levinseni in having no avicularium.

  • Seventy-one species of the order cheilostomatous bryozoans are reported from coasts of southern Korea. Among them, Callpora inaviculata and Integripelta meta are described as new species and the following eight species are reported as new records of Korea: Membranipora irregulata, Tegella crenulata, Beania regularis, Celleporaria brunnea, Exochella tricuspis, Calyptotheca parcimunita, Microporella borealis, Celleporina rostellata.

The genus has been known only by the type species, A. cyanopa Meyrick from N. India. Image of adult, forewing venation and illustrations of the male genitalia with aedeagus for the new species are provided.

  • A new species of Chrysosplenium (Saxifragaceae), C. epigealum J.W.Han & S.H.Kang is described from Mt. Seoraksan, Inje-gun, Gangwon-do, Korea. This new species is distinct from C. flaviflorum Ohwi, its closely relative species, in having calyx 2-2.5 mm long, pistils slightly shorter than calyx, filaments 2-3 times longer than anthers and stolons epigeal.

  • A new marine halacarid species of the genus Agauopsis Viets, 1927 (Acari: Halacaridae) is recorded from Jeju Island, Korea. Agauopsis tetrasetosa n. sp. belongs to the microrhyncha group in sharing one ventral and three ventromedial spines on tibia of leg I, of which two ventromedial ones are adjacent to each other, with its 20 congeneric members. Agauopsis tetrasetosa n. sp. is most similar to A. miliaris Bartsch, 2005 and A. similis Bartsch, 1979 in sharing the similar chaetotaxy of legs I-IV, positions of the second and fourth dorsal setae, and non 'H'- or 'M'-shaped costae on anterior dorsal plate. However, the new species is distinguished from them by four pairs of perigenital setae in female, the relatively anterior location of gland pores on posterior dorsal plate, and three ventral spines on the tibia of leg II. We describe the new species herein, with detailed illustrations under a differential interference contrast microscope. We also make some brief comments on the affinities between the congeneric species of the microrhyncha group and the new species, based on a tabular key to species of the group.

  • This paper describes six new species of sponges in the genus Agelas from Kosrae Island, The Federated States of Micronesia. Most Agelasid sponges are known from only tropical regions. All the new Agelas species; A. fragum n. sp., A. kosrae n. sp., A. purpurea n. sp., A. bakusi n. sp., A. vansoesti n. sp. and A. incrustans n. sp. are compared with other valid species that were studied. Six new species differ from the other species by morphology, growth form, skeletal fibres, habitats and spicule size. Agelas fragum n. sp. is characterized by its tuberculate surface and primary fibres with brush-like spicules. Agelas kosrae n. sp. is differs in skeletal structure and have tertiary fibres. Agelas purpurea n. sp. is characterized by primary, secondary and tertiary fibres are all cored with spicules. Agelas bakusi n. sp. is similar to Agelas clathrodes in shape, but differs in the primary fibres. Agelas vansoesti n. sp. is characterized by having acanthostrongyles. Agelas incrustans n. sp. is distinguished by its encrusting and not cavernous interior.
