  • The fungal strain, designated KNU16-008, was isolated from field soil in Chungcheongnam-do, Korea. The isolated fungi was characterized by morphological and phylogenetic analyses. Isolated fungus showed typical morphological characteristics of the genus Sporothrix. Based on its phylogenic analysis using internal transcribed spacer (ITS) of rDNA and ${\beta}$-tubulin gene sequences, the strain KNU16-008 was identified as Sporothrix stylites. This species has not been previously reported in Korea.

  • Fungi of the Metarhizium genus are a very versatile model for understanding pathogenicity in insects and their symbiotic relationship with plants. To establish a co-transformation system for the transformation of multiple M. robertsii genes using Agrobacterium tumefaciens, we evaluated whether the antibiotic nourseothricin has the same marker selection efficiency as phosphinothricin using separate vectors. Subsequently, in the two vectors containing the nourseothricin and phosphinothricin resistance cassettes were inserted eGFP and mCherry expression cassettes, respectively. These new vectors were then introduced independently into A. tumefaciens and used to transform M. robertsii either in independent events or in one single co-transformation event using an equimolar mixture of A. tumefaciens cultures. The number of transformants obtained by co-transformation was similar to that obtained by the individual transformation events. This method provides an additional strategy for the simultaneous insertion of multiple genes into M. robertsii.

  • A taxonomic review of the subtribe Astenina in Korea is presented. Five species and two genera are recognized, four species of which are recorded for the first time in Korea [Nazeris opatatus (Sharp), Astenus brevipes (Sharp), A. porosus (Sharp), and A. suffusus (Sharp)]. The genus Nazeris Fauvel is new to Korea. The key and diagnosis of each species are presented. [Taxonomy, Insects, Coleoptera, Staphylinidae, Paederinae, Astenina, Korea].

  • The Red-Back Spiders (Latrodectus hasselti) were found in all parts of Australia except in the hottest deserts and on the coldest mountains. The spider is now generally recognized as being the same family as the Katipo Spider of New Zealand and the Black Widow Spider of America. This species is the only representative of the genus Latrodectus in Australia. The Red-Back Spider was probably the most common cause of serious spider bites between 1927, when records were first kept, and 1956, when an anti-venom became available. The authors redescribe and figured detailly Red-Back Spider,L. hasselti, which was collected during a field trip of Australia.

  • Eighty one specimens of nhodeus sericeus (Pallas, 1176) were collected at the upper stream of the Som River (37$^{\circ}$32' 38" N, 127$^{\circ}$58' 57" E: Maegok-ri, Konggun-myon, Hoengsong-gun, Kanguvon-do, Korea) which is a tributary of the Namhan River. This is the first report of the species in the southern part of the Korean Peninsula. This species is well discriminated from the other species in the genus nhodeus by the following respects. The number of scales of transverse series is more than 34 (range 34-37, mean 35.7 $\pm$0.7). Head is echo감or and snout is Bonder than those of the other species. The upper part of the eve is always black and the lateral body surfaces are reddish purple. It had been hem that the southern limit of the distribution of Rhodeus sericeus was the Yonghung River in Hamgvongnam-do, north-eastern part of the Korean Peninsula. But their distributional range is extended more southerly to the Han River system which tons westward through the central part of the Korean Peninsula.Peninsula.

  • The small shrimp of the genus Acetes which is abundantly distributed in shallow waters along the western coast of Korea has long been considered as Acetes japonicus Kishinouye. In the other hand Liu(1956) has suggested that A. chinensis was possibly distributed in Korean waters, judging from the information from Yoshida(1941), but none of the specimen was collected from this area. After careful examination of the specimens of Acetes collected from the station (37$^{\circ}$39'N, 126$^{\circ}$23'E) in Sokmo channel, central part of Korea authors agreed that the population distributed in this area is consists of Acetes chinensis Hansen. In the present paper the diagnosis of Korean species of Acetes chinensis has first described with taxonomic revision and it is the new record for Korean waters.

  • An aquatic oligochaete species, $Ripistes$ $parasita$ (Schmidt, 1847) collected from Ganghwado Island in Korea, is described and illustrated. Specimens inhabiting on aquatic vegetation at the edge of the streams were collected with a plankton hand net. Morphological features of present specimens such as the number of long hair chaetae per bundle and their length in VI-VIII, and shape and size of ventral chaetae are concordant with those of previous reports on this species. The genus $Ripistes$ contains one species, $R.$ $parasite$ which is distributed over, Europe, North America and eastern part of Asia including China and Japan. This is the first record of $R.$ $parasita$ in Korea.

  • The field-cricket $Turanogryllus$ $eous$ Bey-Bienko, 1956 and its genus $Turanogryllus$ Tarbinsky, 1940 were recorded for the first time from Chungcheongbuk-do province in Korea to carry out the project 'The sound guides to Korean animals.' Depending on the discovery of the cricket, its distributional ranges are more widened towards East Asia to the Korean peninsula from China mainland, the $Turanogryllus$ was 10th to known Gryllinae genera in Korea. Description, photos of habitus, figure of male genitalia, oscillogram and spectrogram for the calling sound are provided for aid identification. Voucher specimens are deposited in the collection of National Institute of Biological Resources, Incheon, Korea.

  • The opossum shrimp, Siriella Dana, 1850 belongs to the family Mysidae Haworth, 1825. It is the genus of an enormous number of species with frequent morphological variations comprising 84 valid species to date. Among the species, Siriella trispina Ii, 1964 has been recorded from the Yellow Sea and the East China Sea is reported from Korean water for the first time. Siriella trispina is characterized by its exceedingly elongated 5th pair of thoracopods, the spines on the inner ventral margin of the uropodal endopod armed with secondary spinules, and 4-5 pairs of spines on the base of the telson. In the present study, we describe Korean specimens of the species in detail with photographs and illustrations. Siriella trispina is the 8th Siriella species found in Korean fauna.
