  • Two new species of the genus Nesodillo Verhoeff, 1926, N. kimi and N. philippinensis, are described from Philippines. For the shape of frontal shield, Nesodillo kimi resembles N. monticola (Vandel, 1973) from New Guinea, but differs from it in the shape of male pleopod 1 exopod. N. philippinensis is distinguished from N. kimi by the shape of frontal shield not depressed in the middle of upper border, and of telson with broadly rounded distal margin.

  • The bivalve molluscan fauna of Ulsan Bay, East Sea coast of Korea, is summarized, based on original and literature data. The fauna consists of 61 species belonging to 20 families. Seven species are identified only to genus level. Two species (Carditellopsis toneana (Yokoyama, 1922), Carditidae and Fulvia hungerfordi (G.B. Sowerby III, 1901), Cardiidae) are new records for the East Sea coast of Korea, and one species (Crenella decussata (Montagu, 1808), Mytilidae) is a new record for Korea. Biogeographically, Ulsan Bay's bivalve fauna is subtropical with a predominance of tropical-subtropical species, 21 species, or 39% of the total species number, subtropical, 14 species, or 26%, and subtropical-boreal (mostly subtropical-lowboreal), 11 species, 21%, totalling 86%. A remarkable feature of the Ulsan Bay fauna is the presence of tropical-subtropical species not found in Yeongil Bay but common in tidal flats and shallow waters of the Yellow Sea and the southern part of Korea. A cold water mass appearing off the southeast coast of Korea near Ulsan in summer seems responsible for the presence of boreal-arctic species in this area.

  • Two newly recorded carnivorous amphipod species, Anonyx gurjanovai Steele, 1986 and A. nugax (Phipps, 1774) belonging to the family Uristidae Hurley, 1963, were collected from the East Sea, Korea. Anonyx gurjanovai is included in the A. laticoxae group and is characterized by a concave palm of the propodus in gnathopod 1 and small posteroventral projection at epimeron 3. The other species, A. nugax, represents the A. nugax group and is distinguished from congeneric species based on the presence of a shorter and less acute projection on epimeron 3. There are 13 species of the A. nugax group recorded worldwide, but this is the first report on the presence of the A. nugax group in Korean waters. Previously, three species of the genus Anonyx had been reported in Korea, and through this study, we have added two newly recorded species. Both the newly recorded Anonyx species are illustrated and compared with the related species. A key to the Anonyx species in Korea is also provided.

  • In Korea ,little attention was paid to chiggers until 1950 so only to reports on four species of chiggers were pulished before Korean War. Since 1950 (beginning of Korean War), a marked progress in the study of chiggers has been made in connection with investigations of Epidemic hemorrhagic fever occurring among the United Nations troops which was suspected as a chigger-borne infectious disease and the first report of tsutsugamushi disease in Korea called natives attention to chiggers as the vector mites of this newly known disease in Korea. This paper is mostly based on specimens of author's collections from 3269 Rodentia Insectivora, 9 Chiroptera, 24 Aves , 35 Amphibia and 3 Reptilia during the time from December 1955 to December 1956 but four species were introduced here from works of others . There are reported here five species of chiggers previously known only out of Korea and a new species also. This new species was collected by author but Lipovsky informed his colleague had collected the same one in Korea and they would publish it as new one in near future. This is the reason of describing the new species without specific name . Of course, this paper is incomplete in view of the geographic distribution, seosonal change and host relation etc, but will serve as a brief summary of the chiggers fauna of Korea up to the present. This species described here are as follows : Gahrliepia brennani var. ventralis Neoschongastia posekanyi Euschongastia kigtajimai Euschongastia miyagawai Euschongastia koreaensis Trombicula nagayoi Trombicula japonica Trombicula pomeranzevi Trombicula mitamurai Trombicula tamiyai Trombicula palpalis Trombicula orientalis Trombicula pallida Trombicula scutellaris Trobmicula miotis Trombicula hiranumai Trombicula sp. Trombicula hiranumai Trombicula sp. Trombicula subintermedius Shunsennia tarsalis . Euschongastia ikaoensis . Trombicula koomori Trombicul subakanushi

  • Two freshwater cyclopoid species including a new species are added to Korean copepod fauna: Ochridacyclops coreensis n. sp. and Itocyclops yezoensis (Ito, 1953). Both species were collected from the semi-subterranean waters like springs and wells. The present paper deals with the description of the new species and the systematic accounts on the two species, based on the morphological character comparison with the related congeners.

  • The following seven species of soil enchytraeids belonging to five genera were collected from Korea: Enchytraeus buchholzi $Vejdovsk{\acute{y}}$, 1878, Enchytraeus irregularis Nielsen & Christensen, 1961, Fridericia bulboides Nielsen & Christensen, 1959, Hemifridericia parva Nielsen & Christensen, 1959, Henlea perpusilla Friend, 1911, Henlea ventriculosa (Udekem, 1854), and Marionina argentea Michaelsen, 1889 sensu lato. Species were found in soil and litter layers of sites investigated in 2007, 2008 and 2014. Diagnoses or descriptions for these species are provided here with new micrographs or drawings.

  • To find unrecorded diatom species in the Nakdong River Estuary and Yeongil Bay, bottom sediments in the estuary, and seagrasses in the bay were collected from 12 sampling sites. Eighteen species and four genera are added to the national flora of diatom as newly recorded one. In the Nakdong River Estuary, twelve species are new records to Korea, Martyana atomus (Hustedt) Snoeijs, Pseudostaurosira perminuta (Grunow) Sabbe & Vyverman, Trachysphenia acuminata M. Peragallo, Trachysphenia australis Petit, Fallacia clipeiformis ($K{\ddot{o}}nig$) D.G. Mann, Amphora graeffeana Hendey, Amphora jostesorum Witkowski, Metzeltin & Lange-Bertalot, Amphora ostrearia var. vitrea (Cleve) Cleve, Amphora wisei (Salah) Simonsen, Halamphora eunotia (Cleve) Levkov, Halamphora lineata (Gregory) Levkov, Nitzschia littorea Grunow. In Yeongil Bay, four species are added as new, Licmophora gracilis var. anglica ($K{\ddot{u}}tzing$) H. Peragallo & M. Peragallo, Tabularia investiens (W. Smith) Williams & Round, Nitzschia composita Giffen, Nagumoea neritica Witkowski & Kociolek. Two species occurred simultaneously in both regions, Fragilaria cassubica Witkowski & Lange-Bertalot and Hyalinella lateripunctata Witkowski et al.

  • In the family Hydroptilidae, Trichoptera, 11 species in 3 genera, Hydroptila Dalman, 1819, Oxyethira Eaton, 1873 and Stactobia McLachlan, 1880, have been recorded from the Korean Peninsula but, until now, no species in the genus Orthotrichia Eaton, 1873. In this paper, we describe a new Korean species, Orthotrichia coreana sp. nov., based on adult specimens from the middle reaches of rivers in the southern region of the peninsula. This species is similar to O. iriomotensis Ito, 2013 from the southernmost region of Japan, but is clearly discriminated from the latter by features of the male and female genitalia.

  • Hypsicera has been reported six species from South Korea. In this study, we reviewed 13 species of South Korean Hypsicera including seven newly recorded species from South Korea. Female of H. brevicornis and H. nigribasis are reported for the first time from South Korea since first record. Additionally, H. incarinata and H. yoshimoboi are reported new to China. We provide diagnoses of six newly recorded species and descriptions of two new females. We also provide photographs of key characters of seven newly recorded species and a key to 13 species of South Korean Hypsicera.

  • Previously, 13 species in six genera of the subfamily Banchinae and 29 speices in 16 genera of the subfamily Pimplinae were known from Korea. In this paper, two species, Rynchobanchus minomensis (Uchida, 1933) and Theronia laevigata nigra Uchida, 1928 are new to Korea. Also, the genus Rynchobanchus is recorded for the first time in Korea. Only one species of Theronia, Theronia atalantae (Poda, 1761), was recorded from Korea by Uchida (1928). New Korean names proposed for these two species are "Eol-gul-ga-si-maep-si-beol" and "Geom-jeong-nap-jak-maep-si-beol" for the R. minomensis and T. laevigata nigra, respectively. A key to the species of Theronia, diagnosis and photographs of diagnostic characters of them are provided.
