As part of taxonomic studies on Korean Chironmidae, the adult midges collected in mostly Asan-gun area of Chungchong-namdo were slide-mounted for permanent preparation and 21 species were identified , of which two species (Polypedilum masudai and Pentapedilum uncinatum) are the first findings in Korea and three species are found to be new. They are named Pentapedilum pseudotritum, n.sp. Cladotanytarsus sinjongensis, n. sp. and Rheotanytarsus dogoensis, n.sp. As a result , the Korean fauna of chironomidae consists of 36 species, 22 genera.

The wing morphometric characters of P.elaeagni complex feeding on the genus Elaeagnus plants was analysed by the multivariate methods using clustering of generalized distance and discriminant analysis. On the clustering of the species, the effect of sexual differences, seasonal variation and geographic population sensitively appeared . However, four species of this group was precicely divided by the discriminant analysis.

In addition to the 52 species and 8 subspecies of archeogastropods that have been reported from Korean waters, 9 species are found to be new to the fauna of Korea ; Diodora sieboldii (Reeve), Montfortula pulchra A. Adams, Colisella langfordi Habe, Notoacmea gloriosa Habe, Mesoclanculus ater (Pilsbry) , Cantharidus hirasei (Pilsbry), Guildfordia triumphans (Pilsbry), Tristichotrochus aculeatus (Sowerby), Homalopoma sangarense(Schrenck). The Korean marine archeogatropod fauna comprises 4 suborders, 5 superfamilies 10 families , 61 species and 8 subspecies.

The family Geometridae, which is one of the most species-rich taxa of Lepidoptera, includes more than 23,000 species worldwide and over 800 species in South Korea. Herein, we record six species of Geometridae for the first time in Korea. Jodis urosticta and Jodis amamiensis can be characterized by their greenish wings and strongly dentate ante- and postmedial lines on the fore and hindwings. These species can also be separated by the shape of the valva of the male genitalia. Pelagodes antiguadraria can be characterized by their greenish wings, whitish medial bands on the forewing and whitish postmedial line on the hindwing. Brabira kasaii can be characterized by the thick grayish band-shaped central fascia of their fore- and hindwings. Sauris marginepunctata can be characterized by the greenish ground color of the forewing, the dark ochreous medial bands and subterminal line and the grayish hindwing. Philereme vetulata can be characterized by their dark brownish wing color and the band-shaped central fascia of the forewing, as well as the medially projected postmedial line of the hindwing. Echthrocollix minuta can be characterized by their pale grayish wing color, brownish postmedial and subterminal lines and large discal dot.

The genus Iksookimia (Actinopterygii: Cypriniformes: Cobitidae) is a bottom-dwelling freshwater loaches, which are well-known as their endemism and high geographic variation. However, population genetic relationships among Iksookimia spp. have remained unclear due to a shortage of genetic markers that can be applied generally in the genus. Here, we developed high-resolving microsatellite markers using I. koreensis and I. longicorpa as representatives of Iksookimia species because of their wide distribution range and phylogenetic position. Ten of polymorphic microsatellite loci were isolated from Iksookimia koreensis and were successfully cross-amplified in I. longicorpa. The mean number of observed alleles per locus was about 10.4 (range, 2-17) for I. koreensis and about 13.2 (range, 2-24) for I. longicorpa. The loci, IK03 and IK08, deviated from the Hardy-Weinberg equilibrium in I. koreensis, after applying the Bonferroni correction. The microsatellite markers obtained in the present study will be useful to evaluate population genetic structure and to establish conservation strategies for I. koreensis and related Iksookimia species.

This study reports three species in the genus Tubastraea from Korea: Tubastraea coccinea Lesson, 1829; Tubastraea faulkneri Wells, 1982; and Tubastraea micranthus (Ehrenberg, 1834). Tubastraea faulkneri and T. micranthus are newly recorded in Korea. The specimens of three species were collected in the subtidal zones off Jeju-do between 1991 and 2010. The two newly recorded species were described in detail based upon the morphological characters of skeletal structures. The previous records of T. coccinea in Korea were supplemented with additional data in the remarks. These three species have a straight septal arrangement or irregular septal fusion in common as a main character for the genus Tubastraea, but they differ with respect to the growth form, intercorallite distance, exsertness from common coenosteum, and the detailed characters of septal arrangement. Tubastraea faulkneri is similar to T. coccinea in its plocoid growth form, well developed common coenosteum, and corallite size. However, unlike the latter species, the former species is characterized by rare or absent budding adjacent to the corallite edges, wider intercorallite distance, and irregularly developed septal fusion near the columella. In particular, T. micranthus is distinguished by an axial dendroid growth form, and the smallest corallites in this genus.

A winged midge species, Parochlus steinenii is one of the most abundant species in Antarctica, which is distributed over a wide area from the South American continent to the South Shetland Islands in Antarctica. It was dispersed into islands in the South Shetland Islands from the South American continent, and it adapted to a variety of environments and settled. This species, therefore, is a good model organism to explain the evolutionary process of Antarctic terrestrial fauna. Nevertheless, there are few genetic studies on this species, which are necessary for understanding the genetic diversity, population structure, etc. Here, we developed and characterized 14 polymorphic microsatellite markers. The number of alleles per locus ranged from 2 to 5. The observed and expected heterozygosities were in the range of 0.024 to 0.561 and 0.024 to 0.535, respectively. Identifying genetic differences between populations, they are suitable markers for researches investigating genetic diversity and population structure of P. steinenii, which provide us with clues to dispersion, evolution and ecology of this species.

Branchinotogluma segonzaci (Miura and Desbruyères, 1995) occurs in hydrothermal vent fields of the southwestern Pacific Ocean. We morphologically compared B. segonzaci from the North Fiji Basin with the original description from the Lau Basin and a subsequent study of specimens from the Manus Basin. The main characteristics of all B. segonzaci populations were similar having 21 segments, 10 pairs of elytra, cylindrical-shaped anterior lobes, and ventral papillae on segment 12 and ventral lamellae on segments 13-17 in males. However, the specimens from the North Fiji Basin had rounded to sub-renifrom elytra rather than oval in the original description. Additionally, we newly obtained 11 cytochrome oxidase subunit I (COI) DNA barcodes from the North Fiji Basin and Tonga Arc populations and compared them with known COI DNA barcodes of Branchinotogluma species. Thirteen sequences of B. segonzaci showed 0.0-1.07% intraspecific variation and formed two clades in the COI neighbor-joining tree, whereas the interspecific variation among Branchinotogluma species was 8.19-22.4%. The results of this study contribute to biogeographic studies of B. segonzaci and the evolution of polynoid scale worms in chemosynthesis-based ecosystems.
