  • Ixodes signatus nymphs were subjected to the scanning electron microscopy for the observation of the major physiological sense organs including the Hailer's organ. Finger prints and variable sensory setae were found on the body surface, and especially well developed setae were identified on the article IV and on the anal lobes. A central button-like organelle and numerous small holes were found in the spiracular plate. The Haller's organ was identified at the distal point of the tarsus I and regarded as the major sensory organ, chemoreceptor. Tow types of sensory setae were observed, the shorter ones in front of the organ and the longer ones in distal front as well as near behind of the organ. The fully opened organ was ellipsoidal and a total of seven basiconic sensory pegs rooted deeply and shaped as well arranged hook-like was found inside the organ.

  • The sterile form of Inonotus obliquus is used for preparation of the medicine befungin that is effective in the treatment of gastritis, gastric ulcers, and several tumors. The fungus is known to be produced mainly on the stems of Betula platyphylla var. japonica that grows at high altitudinal (above 1,100 m) region in Korea. But, we found the mushroom on the stem of Betula costata at Mt. Jumbong in Korea. We isolated a pure culture of the fungus from the stem of B. costata by use of potato dextrose agar (PDA) medium with streptomycin. We could isolate the fungus from plant's tissue filled with hyphae, but not from other parts. The spore collected from the sclerotia showed $6.0{\sim}10.0{\times}4.5{\sim}6.0{\mu}m$ in diameter, and the hypha was $2.5{\sim}5.0{\mu}m$ in thickness. The colony showed irregular features and scattered yellow color at the center as the culture ages. We could find brownish setae at the yellow region of colony at 20 days of culture, and the size ranged $4{\sim}6{\times}100{\sim}420{\mu}m$. The oatmeal agar (OA) provided best growth for I. obliquus among five media (CDA, CMA, MA, OA and PDA). Optimum temperature ranged $25{\sim}30^{\circ}C$, and optimum pH was relatively alkaline with the range of pH 8.0~9.5.

  • Two new species of siphonostomatoid copepods, Asterocheres tubiporae n. sp. and Entomopsyllus stocki n. sp., associated with the stoloniferan coral Tubipora musica (Linnaeus) are described from Madagascar. Asterocheres tubiporae is characterized by the possession of a large posteroventral process on the caudal ramus and the elongated free segment of leg 5. Entomopsyllus stocki is readily distinguished from its congeners by the possession in the female of 15-segmented antennule and three spines plus two setae on the third exopodal segment of leg 4.

  • In this paper we represent a new species, Cteniobathynella ahnerti sp. nov., from South America. The new species is characterized by the heterodont teeth on free margin of labrum, the spine row of the mandible consisting of four thick spines, the presence of two setae on outer distal margin of distal segment of maxillule, the prehensile nature of maxilla and the oblique arrangement of two spines on sympod and the presence of a median spine on the endopod of the uropod.

  • A spionid polychaete, Scolelepis (Scolelepis) kudenovi Hartmann-Schroder, 1981, is newly reported from Korean waters with description and illustration. Scolelepis (Scolelepis) kudenovi is characterized by a combination of the following morphological features: the notopodial setae are present on the setiger 1; the occipital tentacle is absent; the branchiae are partially fused to the notopodial postsetal lamellae; the notopodial and neuropodial hooded hooks are bidentate only; the notopodial hooded hooks are present on the posterior setigers. A key to Scolelepis species from Korean waters is provided in this paper.

  • Paramolgus orientalis n. sp. is described as an associate of the antipatharian coral Antipathes japonicus from Jeju Island, Korea. The new species is distinguished from its three relatives P. constrictus, P. delicatulus, and P. insectus, all known from antipatharians in tropical waters, by its long caudal ramus which is more than four times as long as wide, by the possession of 4 setae on maxillule, and by other morphological differences in the antenna and maxilla.

  • Pseudanthessius spinosus n. sp. is described as an associate of the sea urchin Clypeaster japonicus Doderlein from Cheju Island in Korea. The new species may be easily distinguished from its congeners by having four spines and five setae on the third exopodal segment of leg 4. It is the second known species of the genus from Korean waters.

  • The primitive beachflea, Paciforchestia pyatakovi (Derzhavin, 1937) living in gravel beaches was previously reported only from Japan and Russia. This species can be easily distinguished from another species in the same genus, P. klawei (Bousfield, 1961), by the degradation of all plepods and both rami that each consist of single article bearing 2-4 distal plumose setae. Descriptions of the diagnostic characteristics of the species are presented.

Pedetontinus aureus is characterized by the peculiar scale pattern and long ovipositor, and Pedetontinus rhombeus by the large body size and field of short suberect setae of article III of maxillary palpus. The genus Pedetontinus amounts to four species including two new species of this study in Korea. Descriptions, remarks and biological notes are given.

  • First zoeas of Alpheus albatrossae (Banner, 1953) are described and illustrated for the first time, based on laboratory-hatched zoeas from a female collected in Ulleung-do Island, eastern Korea. The first zoeas of A. albatrossae can be distinguished from those of seven known species of Alpheus (A. brevicristatus, A. digitalis, A. heeia, A. japonicus, A. lobidens, A. richardsoni, and A. sudara) from Korea by having 6-segmented scale of the antenna and the endopod of the first maxilliped with four terminal setae.
