  • Mylonchulus jinjuensis n. sp. is 1.8-2.2 mm long, spicules 58-$67{\mu}textrm{m}$ long and is distinguishable by basally situated subventral teeth, presence of hypodermal glands and ventural body pores. Mylonchulus taeguensis n. sp. is 1.3-1.8 mm long, spicules 52-$64{\mu}textrm{m}$ long and is characterized by having small denticle on dorsal wall of buccal cavity at the level of dorsal tooth apex, and two each pre- and post-vulval papillae. Mylonchulus polynicus is reported here for the first time from Korea, is described and illustrated. Princhulus pachydermis n. sp. is 2-2.3 mm long and is distinctive in having very thick body cuticle and absence of caudal glands and spinneret. Prionchulus koriensis n. sp. is 1.7-2.0 mm long and is characterized by having elongate-conoid tail with sharply pointed terminus and presence of caudal glands.

  • Among taenited tapeworms inferting humans though pork or beef, Taenia solium Linnaeus 1758 and Taenia sagina Goeze 1782 have already been. Based on the morphologic characteristics of adult and metacestodes of Asian Taenia saginata, the third kind of human taeniid tapeworm konwn to disdute in Asian counteries, a new spscies name of Taenia asiatica is proposed. In addition to the known biology in their intermediate hosts, T.asiatica was diffierent morphologically from Taenia saginata Goeze 1782 in having the unarmed rostellum on the scolex of adlut, the large number of 'unterinetwigs' and the existence of 'posterior protuberance'. These structures in the gravid proglottids were used as taxonmic keys in taeniid tapeworms for the first time. T. asiatica metacestode (Cysticercus viscerotropica)was different morphologically from T. saginata metacestode (Cysticercus bovis) in having wartlike formations on external surface of the bladder wall.

  • Two Neanurid species of Collembola, Lobella minuta n. sp., and Morulina triverrucosa Tanaka, 1978 were identified from collections of South-Western part of Korea. They were, in addition, confirmed to be genera of new record to the country. From their common structure of simple mouth parts it was postulated that they may have both hypertrophy and polytene development of salivary glands in the light of early evidences by Cassagnau. These assumptions were tested for the above two Korean species using cytological and histological techniques. The results of the investigations have proved to be positive for the postulations, thus supporting hypothetical correlations of simple mouth parts with polytene development, irrespective of taxa, not limited to Neanurini as indicated in early works. However the structurization of the polytene chromosomes was shown of different extent between the two, i.e., in Lobella minuta, clearly more differentiated than in Morulina triverrucosa in spite of the strong similarity of mouth parts, which are to be seen as a distinct convergence from two tribes, Neanurini and Morulini. It remains to be studied consequently to know whether there as any factor other than mouth part structure affecting polytene development and also if the parallelism among a few different taxa of mouth parts would be the case with polytene development of salivary glands either.

  • A new species of Corydalis sect. Corydalis (Fumariaceae), Corydalis cornupetala Y.H. Kim et J.H. Jeong is described from Gyeongsan-si, Gyeongsangbuk-do in Korea. This new species is distinguished from the other species of the sect. Corydalis by some flower characters such as, purplish white petal with two dark stripes and horn-shaped apex of outer petal. The linear leaflets of C. cornupetala are similar to the lineariloba type of C. remota Fisch. ex Max. or C. namdoensis B.U. Oh et J.G. Kim, but much longer and narrower. The linear or lanceolate bract of C. cornupetala is also distinctive from the elliptical shape of C. remota and C. namdoensis.

  • A new species, Epilobium ulleungensis J. M. Chung (Onagraceae Juss), from Ulleungdo Island (South Korea) was described and illustrated. Among four taxa native to Ulleungdo Island (E. amurense Hausskn. subsp. cephalostigma (Hausskn.) C. J. Chen, Hock & P. H. Raven, E. hirsutum L., E. pyrricholophum Franch. Sav., and E. ulleungensis), E. ulleungensis has a unique tetragonal stigma, which is considered to be an intermediate form between clavate (E. pyrricholophum) or capitate (E. amurense subsp. cephalostigma) and 4-lobed stigmas (E. hirsutum). More importantly, this new species is clearly distinguished from the other three taxa distributed on Ulleungdo Island by its height (over 200 cm), decumbent stem, leaf shape, short, dense pubescent covering on the whole plant, large flower size, and a dark pink or red purple flower. According to the stigma shape and other characters, it was estimated that E. ulleungensis is a hybrid between E. hirsutum and E. pyrricholophum or E. amurense subsp. cephalostigma). The specific epithet "ulleungensis" was chosen because the new species was restricted to Ulleungdo Island.

  • Twenty-one speices of the terrestrial isopods are recorded from Cheju Island and Chja Island, Korea. Quepartoniscus tuberculatus, n. gen., n.sp., is described. The genus Koshiniscus Nunomura is considered to be a junior synonym of Armadilloniscus Uljanin, Armadilloniscus hoshikawai Nunomura and A. amakusaensis Nunomura of A. ellipticus, Mongloiscus nipponicus (Arcangeli) of M. vannamei(Arcangeli), Nagurus tsushimaensis Nunomura, N. pallidus Nunomura, and Mongoloniscus nigrogranulatus Kwon and Tatiti of M. koreanus (Verhoeff). Nagurus sinuosus Nunomura is transferred to Lucasioides Kwon , Protracheoniscus pannuosus Nunomura (of which P.awaensis Nunomura, Nagurus gotoensis Nunomura, and N. izuharaensis Nunomura are synonyms ) to Agnara Budde-Lund, and Armadillo obscurus Budde-Lind to Venezillo Verhoeff. Several poorly known species are redescribed and illustrated.

  • A new species, Pseudostellaria baekdusanensis M. Kim (Caryophyllaceae), has been named and described from Mt. Baekdu of the Korean peninsula. Pseudostellaria baekdusanensis shares several characteristics (same size leaves, axillary or terminal flowers, emaginate petals, etc.) with its related species P. japonica (Korshinsky) Pax. It is, however, distinct from P. japonica which have large plant (25-35 cm), leaf blade margins and midveins with long hairs, shallow emaginate petal apex, (2) 3 styles, and cleistogamic flowers by having small plants (9-13 cm), leaf blade basal margins with long hairs, deep emaginate petal apex, 2 styles, and non-cleistogamic flowers.
