  • Three Loxodes ciliates collected from estuarine littoral, wetland and small pond in Korea, were identified as Loxodes kahli Dragesco and Njin$acute{e}$, 1971, L. magnus Stokes, 1887 and L. vorax Stokes, 1885. The descriptions for these species based on living and protargol impregnated specimens were given. Morphometry, illustrations and microphotographs were also provided. Diagnoses of three species are as follows. Loxodes kahli; size in vivo $160-300{\times}40-70\;{\mu}m$; oral area with reddish to brownish pigments; 6-11 macronuclei arranged linearly; 5-9 micronuclei located near macronuclei; 4-12 M$\ddot{u}$ller's vesicles; somatic kineties on right 18-20 and left 2 in number. L. magnus: size in vivo $250-470{\times}87-15\;{\mu}m$; body colored dark brown; 5-13 macronuclei; 8-13 micronuclei; 8-18 M$\ddot{u}$ller's vesicles; somatic kineties on right 23-26 and left 2 in number. L. vorax: size in vivo $70-160{\times}20-35\;{\mu}m$; oral area with brownish pigments; 2 macronuclei; 1 micronucleus located between macronuclei; 2-4 M$\ddot{u}$ller's vesicles; somatic kineties on right 18-20 and left 2 in number.

  • The subfamily Murinae is a very controversial group concerning their phylogenetic relationship. Previous studies could not resolve phylogeny among four genera Apodemus, Micromys, Mus and Rattus of the Muridae. In the present study, eight rodent species resident in South Korea were collected and phylogenetically analyzed based on sequence data of five mitochondrial and nuclear DNA regions: 12S rRNA, cytochrome b gene (cyt b), cytochrome oxidase II (COII), control region of mitochondrial DNA, and a thyroglobulin (Tg) of nuclear DNA. According to the phylogeny of the concatenated data, M. musculus separated early in Murinae (ML 100%; BA 1.00 pp) and the genus Rattus grouped with the harvest mouse, M. minutes; these were separated from the genus Apodemus with relatively strong support (ML 74%; BA 0.76 pp). The Siberian chipmunk population was also examined using the five genes to obtain better resolution. The phylogeny for Korean rodents determined using the 12S rRNA, cyt b, COII and control regions discriminated the Siberian chipmunk populations from Korea, Russia, and China.

  • Two oxytrichid ciliates collected from the mosses and estuarine littoral in Korea were identified as Oxytricha longigranulosa Berger and Foissner, 1989 and O. marina Kahl, 1932. These species are reported for the first time from Korea. The description was based on living and protargol impregnated specimens. Diagnostic characters for each species are as follows. Oxytricha longigranulosa: Cell in vivo $80-115{\times}30-50{\mu}m$, mostly $90{\times}40{\mu}m$. Length/width ratio about 2.4/1. Cortical granules about $1{\times}1.5{\mu}m$ in size, colorless, arranged in short and discontinued longitudinal rows. Four frontoventral cirri. Adoral zone of membrane lies (AZM) covering 30-50% of cell length with 25-27 adoral membranelles (AM). Buccal area flat, typical Oxytricha pattern. Five transverse cirri, 19-23 right marginal cirri, 19-24 left marginal cirri, three caudal cirri, five dorsal kineties. Two macronuclear nodules 2 in number and spherical in shape, two micronuclei in number. Oxytricha marina: Cell in vivo $100-150{\times}30-60{\mu}m$. Cytoplasm colorless without cortical granules. Four frontoventral cirri. AZM covering 50% of cell length with 28-44 AMs, Buccal area flat, typical Oxytricha pattern. Five transverse cirri, 23-38 right marginal cirri, 19-25 left marginal cirri, three caudal cirri, five dorsal kineties.

  • After the revision of the Korean species of Asthena $H{\ddot{u}}bner$, we additionally added one new species, Asthena koreana sp. nov. and two new records, Asthena hamadryas Inoue and Asthena sachalinensis (Matsumura) from Korea. Asthena koreana sp. nov. can be characterized by the white forewing with a costally bifurcated, loop-shaped antemedial line, black minute discoidal dot and single postmedial line and white hindwing with straight antemedial line and black discoidal dot. Asthena hamadryas Inoue can be distinguished by a white forewing with a costally loop-shaped antemedial line and undulating, double lines of the postmedial line, as well as a white hindwing with four light ochreous waved lines without discoidal dots. Asthena sachalinensis can be distinguished by their whitish forewing with thick light brownish postmedial lines and minute black discoidal dot on the costal loop of the antemedial line and whitish hindwing with light brownish medial lines with minute black discoidal dot. Currently, eight species of the genus are known in Korea. We provided a revised key to the Korean species of the genus.

  • Pseudohelice subquadrata (Dana, 1851) is endangered due to its restricted habitat; hence, it has been designated as a marine protected species and endangered species by law in Korea. It has been recorded only Jeju-do and Geomun-do, Republic of Korea. The present study, is the first report on a cytochrome c oxidase subunit I DNA barcode for P. subquadrata. The maximum intra-specific genetic distance among all P. subquadrata individuals was found to be 0.5%, whereas inter-genetic distance within the same genus was 17.2-21.5% compared with Helice tientsinensis (Rathbun, 1931), H. tridens (De Haan, 1835), H. epicure (Ng et al., 2018), and Helicana wuana (Rathbun, 1931). Our barcoding data can thus be used as reference for restoration and conservation studies on P. subquadrata, which are designated as marine protected species.

  • A new marine interstitial nematode species belonging to the subgenus Quadricoma of order Desmoscolecida is described from Jindo Island, South Korea. The new species, Tricoma (Quadricoma) jindoensis sp. nov., is most allied with T. (Q.) crassicomoides Timm, 1970 in sharing the similar cephalic setae, broadly truncated border of head, lip region including 6 labial papillae, and slender and long spicule among the seven congeners with 44 quadricomoid rings. However, T. (Q.) jindoensis differs from it by the globular protuberance on the penultimate ring, 7 tail rings, and 9 pairs of subdorsal setae in male. This is the first record of Quadricoma nematodes from East Asia.

  • Based on our insect collecting trip to the Is. Jin-do, Jeollanam-do Province from June 29 to July 1, 2005, a total of 573 lepidopterous species belonging to 37 families are reported, with adding 122 species new to the locality During our survey, the most dominant species was Cryptolechia malacobyrsa Meyrick (Oecophoridae), followed by Sandrabatis crassiella Ragonot (Pyralidae) and Yponomeuta tokyonellus Matsumura(Yponomeutidae), and the family Noctuidae (165 spp.) was the most diverse taxon in species number. We here also discuss the species representing the climatic feature in the island and compare the species diversity with those of other two major islands in Korea, Is. Geoje-do and Is. Jeju-do. Among the species recognized in this study, two species, Epilepia dentata (Matsumura and Shibata) and Meganola costalis (Staudinger) are recorded in Korea for the first time, in spite of the presence of previous notes on the species which is invalid. The adults and genitalia of the two species are illustrated and described briefly.

  • Three species of foreign barnacles were found to invade into Korean interitidal seashores: Balanus amphitrite, B. ebumeus and B. improvisus. The southeastern coast of Korea, near Pusan, is the area where all the specimens of three species were discovered and the populations of these species were well establishe. B. amphitrite is the earliest invader(probably invaded around early 1970's) and most widely distributed in Korea. It is now distributed all around Korea, except the Yellow Sea coast, north of Mokpo. B. improvisus has been successful to expand its reange to the northern part of Korean coast of the East Sea, whereas B. eburneus is restricted to the southeastern coast. B. amphitrite is successfully competing with the native barnacle, B. albicostatus, and in several areas where the mixed populations of the two species occur, the latter species is found to excluded. The Yellow Sea coast has not been invaded by the foreign barnacles, the reason of which is not known.
