Among recent materials identified from Korea two species of Criconematoidea are different from described forms: Criconemella hawangiensis is larger and has a longer stylet than C. paragoodey, head an tail annuli also differ. Hemicycliophora parajuglandis has an outbulging lip area that sits like a hemicircle on the head and pushed the lateral head side inwards; morphology and measurements correspond to H. juglandis and also to H. koreana. Hemicycliophora epichoroides is newly recorded from Korea.

We conducted taxonomic study of Languriinae in Korea. Nine species that belong to two genera of one tribe were identified in Korea. Two species, Anadastus ruficeps (Crotch) and Anadastus praetermissus (Janson), were recorded for the first time in Korea. Description, photographs of adults, illustrations of diagnostic characteristics, and a key have been provided.

Diatoms are a major component of the biological community, serving as the principal primary producers in the food web and sustaining oxygen levels in aquatic environments. Among marine planktonic diatoms, the cosmopolitan Skeletonema costatum is one of the most abundant and widespread species in the world's oceans. Here, we report the basic characteristics of a new diatom-infecting S. costatum virus (ScosV) isolated from Jaran Bay, Korea, in June 2008. ScosV is a polyhedral virus (45-50 nm in diameter) that propagates in the cytoplasm of host cells and causes lysis of S. costatum cultures. The infectivity of ScosV was determined to be strain- rather than species-specific, similar to other algal viruses. The burst size and latent period were roughly estimated at 90-250 infectious units/cell and <48 h, respectively.

Based on morphological observation, we identified nine ciliates previously unrecorded in Korea, Euplotidium itoi Ito, 1958, Anteholosticha verrucosa (Foissner & Schade, 2000) Berger, 2008, Holostichides dumonti Foissner, 2000, Amphisiella australis Blatterer & Foissner, 1988, Terricirra matsusakai Berger & Foissner, 1989, Uroleptoides binucleatus binucleatus Hemberger, 1985, Uroleptoides magnigranulosus (Foissner, 1988) Berger, 2008, Leptopharynx costatus gonohymen Omar & Foissner, 2012, Pseudochilodonopsis mutabilis Foissner, 1981, from three sites in Korea, which were isolated from three environmental samples, consisting of one seawater and two soil samples. These ciliates were assigned to three classes, five orders, five families, and eight genera. In this study, we provide photographs and brief descriptions and remarks of the nine species.

Two harpacticoid copepods, Pseudonsiella longicaudata. n. sp. and Xylora longiantennulata n. sp. belonging to the subfamily Donsiellinae are described. They were found in the wood infested by isopod of the genus Limnoria from the East Sea (Sea of Japan), Korea. The former species is characteristic in having the long caudal ramus and four setae on mandi bular basis. The latter one closely resembles X, nertica Hicks in general body form, but is clearly distinguished from X. nertica in that the antennule is much longer and the caudal ramus is longer, and leg 5 endopod bears four setae.

In this study, we report a genus Macrobathra for the first time from Korea, including one newly reported species, M. quercea Moriuti, 1973. Adult including the genitalia of both sexes are described and photographs of adults and genitalia, distributional ranges and host plants are also provided.

The phylogenetic analysis was carried out to find out the validity of Chrysochroa coreana as a new species. The insect specimens were collected at Kaohsiung, Taiwan and Shizuoka, Japan. Partial region (532 bp) of COI was amplified and sequenced. The sequences were aligned and then analyzed. Based on the Kimura-2-parameter method, we calculated genetic distances among them. It indicated that the Korean individual of C. fulgidissima was closely related to Taiwan one with relatively low genetic distance (0.083). On the other hand, the Japanese individual was remotely related with those of Korean (0.192) and Taiwan (0.183) individuals. To clarify if the populations of C. fulgidissima from Korea, Taiwan, and Japan are different at the level(s) of subspecies, species, or genus, it is necessary that more samples of the members of the family Buprestidae should be collected and genetically analyzed.

In this study, one species of the bag moth, Mahasena aurea (Butler) (Lepidoptera: Psychidae), was found for the first time in Korea as a new insect pest on leaves of Liriope spicata (Thunb.) Lour. Also, the female larvae and adults of the species were first collected in this country. Larvae, pupae, and adults of both sexes are redescribed with illustrations of all external characteristics including the genitalia of the male.

The introduced spider crab Pyromaia tuberculata was collected from Korea in 2005 and it was ovigerous. After hatching, larvae were reared in the laboratory at $20^{\circ}C$. The larval stage of the species consists of two zoeal and one megalopal stages. The larvae of the Korean species differ somewhat from those from New Zealand described by Webber and Wear (1981; N Z J Mar Freshwat Res. 15:331-383) and from Brazil described by Fransozo and Negreiros-Fransozo (1997; Crustaceana. 70:304-323.) in the setal presence of the antennule, the maxillule, the maxilla and the maxillipeds, and the abdomen. It is found that Fransozo and Negreiros-Fransozo have overlooked some setae on the basis of the zoeal maxillipeds and that re-examination of their larvae is needed. Also, it is found that the Inachoididae is heterogeneous based on the zoeal morphology because two distinct groups exist in the family.

Some male genitalic characters are given here respectively.
