  • Catinia plana Bocquet and Stock, the type genus and species of the family Catiniidae, which has been known incompletely is redescribed on the basis of type material. Structure of appendages, especially those of mandible and maxilla, are reinterpreted. In addition, two new species of Myzomolgus associated respectively with the sipunculids Sipunculus nudus Linnaeus and Siphonosoma cumanense (Keferstein) are described from Korean waters. A comparison of already known species of Myzomolgus and two new species of the same genus resulted in a conclusion that members of this genus possess homogeneous traits and the genus is a well established taxon. A key to distinguish five genera of the Catiniidae is also provided.

  • Several osteological characters of 45 species belonging to 26 genera and 4 subfamilies in th family Gobiidae were surveyed based on 348 specimens collected from April, 1984 to September, 1992 in the southern part of Korea. The characters include the following: first dorsal-fin pterygiophore formula, vertebral number, epural number, and number of anal-fin pterygiophores anterior to the first haemal spine. The first dorsal-fin pterygiophore formula and epural number showed considerable stability at the generic level, and the apeared useful characters at the species level. Among them, the epural number used formerly to distinguish gobiid subfamilies was considered to be unimpotant taxonomic character in the classification of the subfamily Gobiinae.

  • This paper reports four species of Erebidae from the southern part of Korea: two Boletobiinae, Honeyania ragusana (Freyer, 1845), Enispa masuii Sugi, 1982, one Hermininae, Adrapsa ablualis Walker, 1859, and one Arctiinae, Stictane rectilinea (Snellen, 1879). Honeyania ragusana can be distinguished by the following: a blackish dot on the apex of the forewing with strongly curved medial lines, a long slender uncus and a strongly distally bifurcated valva with a large distally expanded costa and a thumb-shaped process of sacculus on the male genitalia as well as a sclerotized antrum, strongly tapered ductus bursae, and large corpus bursae on the female genitalia. Enispa masuii, a lichen feeder, can be distinguished by the whitish medial lines of the grayish fore- and hindwings, and a pair of rounded ball-shaped lamella antevaginalis, long, sclerotized ductus bursae, and pear-shaped corpus bursae without signum of the female genitalia. Adrapsa ablualis can be distinguished by the whitish medial lines of the fore- and hindwings and large medial process of the costa and dentate distal margin of the valva of the male genitalia. Stictane rectilinea can be distinguished by the broad dark grayish medial band of the forewing and the long knife-shaped valva with a strongly hooked process on the distal part of the sacculus of the male genitalia.

  • Isaacsicalanus paucisetus Fleminger, 1983, a monotypic species of the family Spinocalanidae Vervoort, 1951, was first reported from a hydrothermal vent field in the East Pacific Rise off the mouth of the Gulf of California. The mitochondrial cytochrome oxidase I(mtCOI) DNA barcodes are considered a useful tool to assist traditional taxonomy and species discrimination in calanoid copepods. However, the mtCOI DNA barcodes of I. paucisetus have not been reported due to the species rarity and the difficulty of sampling. In this study, we firstly determined the mtCOI DNA barcodes of the I. paucisetus newly collected from a hydrothermal vent in the North Fiji Basin of the southwestern Pacific. All mtCOI DNA barcodes of I. paucisetus were identical and intraspecies variations of spinocalanid species were 0.0-3.0%. Interspecies and intergeneric variations were 13.4-25.2% and 16.7-24.1%, respectively. The DNA barcodes of I. paucisetus obtained in the present study would be helpful for understanding taxonomic relationships of widespread spinocalanid species.

  • The antipatharians in Korea were known with three species and two genera belonging to family Antipathidae. In the present study, three species, Antipathes densa, A. grandiflora, and A. dubia, have been newly recorded to Korean antipatharian fauna with the samples collected from Jeju-do during the period from 2003 to 2005. The description was mainly based on the habitat, the branching mode of corallums, the size and arrangement of polyps and spines on the axis, and also the types of cnidae. They had three kinds of cnidae: spirocyst, basitrich, and microbasic p-mastigophore. Spirocysts and basitrichs were distributed at tentacles and microbasic p-mastigophores were mainly at septal filaments.

  • A new marine tardigrade species of the genus Orzeliscus belonging to the family Halechiniscidae is described from the sea coasts of Korea and Japan. This new species is most characterized in having slender, pole-shaped clava with uniform breadth along its whole length. Furthermore, it evidently differs from the congeners by the combination of characters of a hemispherical protrusion on cheek region of the head, a big and bulbous lateral projection between leg III and leg IV, and an elongate papillus terminating with a minute tube on leg IV. 'Orzeliscus cf. belopus' sensu McKirdy, Schmidt and McGinty-Bayly, 1976 from the Galapagos Islands quite resembles this new species in sharing the slender, pole-shaped clava. However, these two Pacific populations are distinguished to each other by body size and shapes of the protrusion on cheek region and the lateral projection between leg III and leg IV. Scanning electron microscope photographs and a key to species of the genus Orzeliscus are also provided herein.

  • Purpose: A national long-term care system for elderly and the disabled has its unique evolution in each country. Japan, Germany and the United States may be the typical examples of respective social insurance system. This paper reviews the counterpart examples of Japan, Germany and the United States and looks at their accumulated long-term care system experiences and personal care system under workers' compensation. Methods: Literature review and website searching were conducted. Key words as 'workers' compensation insurance', 'personal care benefit' and 'long term care' were used in searching the related literatures. Results: Though the personal care benefit under current Workers'Compensation in Korea is very similar to Japan's, the long-term care system of Korea is not as well established. Germany and the United States have the provision of personal care benefit for injured workers within long term care system. Conclusions: We recommend some key issues to take into account for improving personal care benefit system in workers' compensation in Korea as follows: providing a comprehensive coverage through the linkage of long term care, introducing an assessment & evaluation system for the appropriate benefits, establishing insurer's role for quality management of personal care service, and developing a policy for family caregivers.

  • DNA barcoding of Bryozoa or "moss animals" has hardly advanced and lacks reference sequences for correct species identification. To date only a small number of cytochrome c oxidase subunit I (COI) sequences from 82 bryozoan species have been deposited in the National Center for Biotechnology Information (NCBI) GenBank and Barcode of Life Data Systems (BOLD). We here report COI data from 53 individual samples of 29 bryozoan species collected from Korean seawater. To our knowledge this is the single largest gathering of COI barcode data of bryozoans to date. The average genetic divergence was estimated as 23.3% among species of the same genus, 25% among genera of the same family, and 1.7% at intraspecific level with a few rare exceptions having a large difference, indicating a possibility of presence of cryptic species. Our data show that COI is a very appropriate marker for species identification of bryozoans, but does not provide enough phylogenetic information at higher taxonomic ranks. Greater effort involving larger taxon sampling for the barcode analyses is needed for bryozoan taxonomy.
