  • A genuine interstitial cyclopoid species belonging to the genus Psammophilocyclops Fryer, 1956 is recorded from the filtration basin of a water treatment plant, South Korea. The genus Psammophilocyclops is very rarely found, and only three species have been recognized as yet: P. boccaroi Fryer, 1956 from Africa, P. trispinosus Shen et Tai, 1964 and P. bispinosus Shen et Tai, 1964 from China. The present new species differs from the congeneric species by the character combination of 11-segmented antennule in female, four-segmented maxilliped with 2,1,1,2 setation, the spine formula of 3,3,3,3, and setal arrangement of 3,3,5,3 on the distal endopodal segments of legs 1-4. Descriptio and taxonomic accounts of the new species are presented with a revised generic diagnosis and a key to the species hitherto known in the genus.

  • A new laophontid copepod species, Apolethon articulatus n. sp., is described from the estuaries and salt marshes in South Korea. Apolethon articulatus is similar to the three congeneric species currently known in sharing the character combination of the elongate first endopodal segment of leg 1 with inner seta and the expansion of second endopodal segments of legs 2-4 with decrease in the number of setae on them. However, A. articulatus differs from them by the separate exopod of female leg 5 and the armature of mandibular palp with 6 setae. Description and taxonomic accounts of the new species are presented herein with detailed illustrations and SEM micrographs. As the true identity of the rarely known genus has not been clarified yet, a revised generic diagnosis is provided with a key to the species hitherto known in the genus.

  • 국내와 외국의 박물관에 보관되어 있는 밤나방과의 한국미기록종 및 비교적 덜 알려져 있는 24종을 보고한다. 한국미기록종은 Hypenodes curvilinea Sugi, Polydesma boarmoides(Guenee), Catocala bokhaica (Kononenko), Xanthomantis contaminata (Draudt), Craniophora harman야 (Poujade), Amphipyra acheron Draudt, Orthogonia tapaishana (Draudt), Chasminodes ussurica Kononenko, Oncocnemis campicola Lederer, Protomiselia bilinea (Hampson)과 Xistia (Anomogyna) albonigra (Kononenko)등 11종이며, 그 중 일본에서만 기록되었던 P. bilinea (Hampson)은 아시아의 대륙에서는 처음 기록된다. 또한 Athetis pallidipennis Sugi, Pseudocosmia maculata Kononenko, Callopistria miracula Herz Lacanobia dentata Kononenko는 한국에 분포하는 종임이 재확인되었다. Eudocyma 와salamina (Cramer)와 Polydesma boarmoides Guenee는 열대지방에 분포하는 종으로서 비래한 것으로 생각된다. 오동정되었던 종 H. rectifascia Sugi는 Hypenodes curvilinea Sugi로 바로 잡는다.

  • A new parasmittinid bryozoan, Parasmittina pyriformis, is reported from four localities in Korea. This new species closely resembles Parasmittina trispinosa in having one to three spines and a triangular avicularium lateral to the orifice. However, P. pyriformis is characteristic in that a single or paired small pear-shaped avicularia are situated lateral to the orifice and a triangular avicularium occurs in laterals to the orifice or on the frontal wall. The new species is also unique in having two spines in most zooids, but rarely one or three spines, whereas P. trispinosa usually has three spines, sometimes two or four.

  • 32 mite species are listed from the Korean Peninsula. One species belongs to the order Prostigmata, family Cryptognathidae, the order Mesostigmata has 20 species and the order Oribatida contains 11 species. Four species from the listed 32 are new for the fauna of the Korean Peninsula, one species belongs to the order Prostigmata (Favognathus maritimus (Shiba, 1969)) and three new species are Oribatida [Camisia biurus (Koch, 1839), Camisia biverrucata (Koch, 1839), Camisia horrida (Hermann, 1804)]. The 28 of the found species are collected in the Democratic People's Republic of Korea; the others were collected in the area of Republic of Korea. Illustrations and short descriptions about the newly found and rarely collected species are given.

  • Fourteen different taxa of dictyostelid cellular slime molds were recovered from the alpine and subalpine zone in Mt. Paektu. In subalpine zone, six species were recovered : Dictyostelium minutum, D. brefeldianum, D. crassicaule, D. capitatum, Polysphondylium solitarium and P. pallidum. One of these species which were isolated from the soils of Larix olgensis community exhibited several distinctive features which differed from the published species. This species was designated as a new species, Polysphondylium solitarium Kang et Chang, sp. nov. When cultivated at 22~24$^{\circ}C$ on low-nutrient agar media with Escherichia coli, Polysphondylium solitarium is distinguishable from other species by the following combination of features: (ⅰ) the sorocarps with vinaceous pigmentation; (ⅱ) pseudoplasmodia radial. usually centralized and rarely subdivided; (ⅲ) the various number of whorls; (ⅳ) the spores with unconsolidated and nonconspicuous polar granules. Also, we confirmed this new species by analyzing ribosomal DNA (ITS1, ITS2 and 5.8s DNA) sequences of P. solitarium and P. violaceum.

  • A new species belonging to the genus Cyclopinopsis Smirnov, 1935 (Cyclopinidae) is described from Korea, as the third species of the genus. Specimens were collected by washing the subtidal sediments off Dokdo Island in the East Sea and the intertidal sands at Baegripo beach, Taean Peninsula on the Yellow Sea coast. Cyclopinopsis deformata n. sp. is characteristic and distinguished from its two congeneric species currently recognized, C. curticauda Smirnov, 1935 and C. brasiliensis Herbst, 1955 in having a deformed seta at the outer distal corner of the third exopodal segment of leg 4. The seta is supposed to be deformed from an outer spine on the third exopodal segment of leg 4, which has been known as completely lost in the genus until now. A character comparison table of the three species and a key to species of the genus Cyclopinopsis are provided herein.

  • Two land snails, Aegista chejuensis (Pilsbry and Hirase, 1908) and Plectotropis quelpartensis (Pilsbry and Hirase, 1908), are endemic to Korea and were collected from Hataedo and Jodo Islands in the Yellow Sea of South Korea, respectively. Many terrestrial snail habitats have been confirmed in Korea; however, their genetic sequences have rarely been reported. This study describes the mitochondrial cytochrome c oxidase subunit I gene (COI) sequences of two species, followed by an analysis of the genetic distance between these two species and their congeners. As a result, there was no intra-species variation in both species A. chejuensis or P. quelpartensis. However, the inter-species variation was clear (10.3-31.5%). We provide photographs and a brief diagnosis for morphological verification.
