    查看更多>>摘要：Platorchestia monodi (Mateus et al., 1986), the beach hopper, commonly lives in sea shores and was previously reported only from the Atlantic regions, such as Mid-Atlantic islands, Brazilian coast, and Israel. We present the first record of this species in the Pacific region. The present species can be clearly distinguished from related species by the shapes of gnathopods 1-2 and development of sexual dimorphism in antenna 2 and pere-opod 7. Descriptions of the diagnostic characteristics of the species are provided on the text. In addition, this paper also provided the partial sequence of the mitochondrial cytochrome c oxidase subunit 1 (COl) gene of the species for its molecular characteristics.

    查看更多>>摘要：Some echinoids were collected from the coast of Gangwon-do during the period from November 2008 to July 2011 and were identified on the basis of morphological characteristics and molecular analysis of cytochrome oxidase subunit I mitochondrial DNA. Among them, Strongylocentrotus pallidus (Sars, 1871) belonging to the family Strongylocentrotidae of the order Camarodonta is reported for the first time in Korea and is redescribed. The genetic differences ranged from 0.038 to 0.139 between S. pallidus and four other species of genus Strongylocentrotus, but ranged from 0.002 to 0.005 between Korean specimens and GenBank data of 5. pallidus. This species is widely distributed in cold sea water along the western part of the North Pacific and the NorthwestAtlantic.

    查看更多>>摘要：The morphology of the two marine urostyloid ciliates, Pseudokeronopsis carnea (Cohn, 1866) and Uroleptopsis citrina Kahl, 1932, in the family Pseudokeronopsidae, collected from the Yellow Sea, and the East Sea, Korea, respectively, were studied usinglive observation and protargol impregnation. Additionally, the small subunit ribosomal RNA (SSU rRNA) gene was sequenced. These two species are firstly recorded in Korea. The main diagnostic key is as follows. Pseudokeronopsis carnea: body outline elongate-elliptical, brown-reddish or orange-red in colour in vivo; bicorona of 16-24 frontal cirri; one buccal and two frontoterminal cirri; 7-10 transverse cirri; 5-7 dorsal kineties; two types of cortical granules (one orange-red pigment, mainly grouped around cirri and dorsal bristles, arranged in typical rubra-pattern; the other, colourless and blood-cell-shaped, and densely distributed); contractile vacuole in the posterior half of the cell on the left side, usually in posterior 1/3-2/5. Uroleptopsis citrina: body outline elongate-elliptical, lemon-yellow in colour in vivo; two types of cortical granules (one yellow pigment; the other, blood-cell-shaped, densely distributed); bicorona of 12-18 frontal cirri; 2-3 frontoterminal cirri; two midventral rows comprising 26-35 cirri (consisting of anterior paired cirri, non-paired single cirri, and posterior paired cirri); three dorsal kineties. In addition, the SSU rRNA sequences of the two species were compared with public database of these species and consequently, showed high similarity.

    查看更多>>摘要：Two urostyloid ciliates, collected from brackish water in Korea, were identified as Diaxonella pseudorubra pseudorubra (Kaltenbach, 1960) Berger, 2006 and Pseudokeronopsisflava(Cohn, 1866) Wirnsberger, Larsen and Uhlig, 1987. The description was basedon living, protargol impregnated specimens. These species are described as follows: Diaxonella pseudorubra pseudorubra: body size in vivo 145-230 x 40-60 mum, elongated ellipsoidal in shape. Cytoplasm reddish and flexible. Adoral zone of membranelles occupied 30-40% of the body; composed of 33-44 membranelles; 1-3 frontoterminal cirri, 1-4 frontal row cirri, 4-6 buccal cirri, 6-10 transverse cirri. Midventral rows composed of 14-24 cirri, four left marginal rows, one right marginal row. Two kinds of cortical granules; the larger one is yellowish and the smaller one is reddish. Pseudokeronopsis flava: body size in vivo 150-210 x 30-45 mum, elongated ellipsoidal shape. Cytoplasm yellowish and flexible. Adoral zone of membranelles occupied 25-30% of body; composed of 44-58 membranelles in number. Frontal cirri forming bicorona composed of 5-7 cirral pairs, 2-3 frontoterminal cirri, one buccal cirrus, and 2-3 transverse cirri. Midventral rows composed of 18-33 cirri, 34-53 left marginal cirri, and 40-58right marginal cirri. Two kinds of cortical granules; the larger one is colorless and "blood-cell-shaped," and the smaller one is yellowish. Diaxonella pseudorubra pseudorubra is different from the most similar subspecies, D. pseudorubra pulchra, in cytoplasmic color and number of midventral cirri. Pseudokeronopsis flava is different from its most similar congeners in pigment granular color, number of bicorona, number of midventral cirri, and position of the contractile vacuole.

    First Records of Two Pontoniid Shrimps (Crustacea: Decapoda: Caridea: Palaemonidae)from Korea

    查看更多>>摘要：We describe and illustrate two pontoniine shrimps, Cuapetes grandis and Periclimenes ornatus, for the first time in Korea. C. grandis was collected in an artifical reef of Dadae, Geojedo Island by SCUBA diving in 15-20 m depth. This species was foundin an oyster within an artificial reef and appeared to be free-living. P. ornatus was collected from Seongsanpo, Jejudo Island by SCUBA diving in 10 m depth. This species had a symbiotic relationship with sea anemone. This record extends their previouslyknown range from southern Japan to the Korean peninsula and the number of known pontoniine species in Korea to four.

    查看更多>>摘要：Adult chironomid collections were carried out near Namdae stream located at Jeollabuk-do, Muju-gun, Muju-eup, Dangsan-ri in 2008 and 2009. Among 21 species of the tribe Tanytarsini identified from Muju collections, six new species (Cladotany tarsus neovanderwulpi, Paratanytarsus paramikesecumdus, Rheotanytarsus parapentapodus, Rheotany tarsus sungili, Tany tarsus neotamaoctavus, and Tany tarsus synyunosecundus) and four previously unrecorded species (Cladotanytarsus vanderwulpi, Paratanytarsus inopertus, Tanytarsus tama-gotoi, and Tanytarsus uresiacutus) were confirmed. They are fully described with illustrations. As a result of this report, the Korean fauna of Tanytarsini consists of 37 species, 6 genera. In total, 128 species, 52 genera, 5 subfamilies of the family Chironomidae are listed in Korea.

    Three Species of Processid Shrimps (Crustacea: Decapoda: Caridea) from Korea

    查看更多>>摘要：Three species of the family Processidae, Hayashidonus japonicus (De Haan, 1844), Processa sulcata Hayashi, 1975 and Processa zostericola Hayashi, 1975 described with illustrations from Korea. Two of these species, H. japonicus and P. zostericola, represent new records for the Korean carcinological fauna. The genus Hayashidonus included the single species, H. japonicus is distinguished from other genera of Processidae by the broadly triangular rostrum, the obscure or absent dorsolateral spines of thetelson, and the exceptionally long molar process of the mandible. Two species of the genus Processa, P. zostericola and P. sulcata are distinguishable each other by presence or absence of an obtuse process of the basicerite of antenna on the antero-ventral margin. The basicerite of antenna arms with the obtuse process in P. zostericola, while in P. sulcata the basicerite of antenna lacks the process but is smooth on the ventral margin. A key to these species is presented.

    查看更多>>摘要：A nolid species, Roeselia triangulalis (Leech) is reported for the first time from Korea. Two males were collected from Jeju Island, South Korea. Roeselia triangulalis can be distinguished by the bipectinate male antennae, broad frons, long labial palpi, costally dark brownish spot and the rounded dark brownish postmedial line of fore wing. In the male genitalia, the long saccus, the slender valve with distally expanded and spine-like harpe and long spinular cornutus of vesica are distinguishing characters. In the female genitalia, the simple sterigma, the long ductus bursae and the large ovate corpus bursae with a lip-shaped signum are distinguishing characters. Diagnosis and description of the species are given with the figures of the male genitalia.
