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.

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.

Sixteen species of macrochelid mites were collected on the surface of scarab dung beetles in Mount Gede-Pangrango National Park, West Java, Indonesia. Of these, one species, Macrocheles gedeensis sp. nov. is described here as new to science. The other fifteen species were Holostaspella katakurai Hartini and Takaku, 2003, H. oblonga Hartini and Takaku, 2010, H. villosa Hartini and Takaku, 2010, Neopodocinum halimunense Hartini and Takaku, 2003, N. subjaspersi Hartini and Takaku, 2003, Neopodocinum sp., Macrocheles dispar (Berlese, 1910), M. entetiensis Hartini and Takaku, 2005, M. hallidayi Walter and Krantz, 1986, M. jabarensis Hartini and Takaku, 2003, M. kraepelini (Berlese, 1905), M. pumilus Hartini, Dwibadra and Takaku, 2009, M. turgoensis Hartini, Dwibadra and Takaku, 2009, M. sukabumiensis Hartini and Takaku, 2003, and M. sukaramiensis Takaku, 2001.

Three ciliate species, Australocirrus australis (Foissner, 1995) Kumar and Foissner, 2015, Rimaleptus longitrichus ($Vd^{\prime}a{\check{c}}n{\acute{y}}$ and Foissner, 2008) $Vd^{\prime}a{\check{c}}n{\acute{y}}$ and Foissner, 2012, and Frontonia subtropica Pan et al., 2013, that were previously unreported in Korea were collected from terrestrial and marine habitats in Korea. Using live observation and protargol impregnation, the three species were identified using a combination of the following characteristics: Australocirrus australis, the distance between the anterior pretransverse cirrus and the anteriormost transverse cirrus (0.6-2.1% of body length) and the arrangement of the transverse cirri (oblique row); Rimaleptus longitrichus, the arrange of contractile vacuoles and longitudinal ciliary rows anteriorly spaced; Frontonia subtropica, number of somatic kineties (approximately 115 rows) and vestibular kineties (5 rows).

Two species of Cryptophlebia: C. nota Kawabe and C. ombrodelta (Lower), are reported from Korea for the first time. This is in fact the first record of Cryptophlebia from Korea, as the previous Korean records of the genus were based on one species, Cryptophlebia hematoma Diakonoff, currently assigned to Thaumatotibia Zacher. Photos of the superficial and genital features are provided for the two Korean species of Cryptophlebia and their distribution and host plants are summarized. Cryptophlebia ombrodelta is recognized as an adventive species in Korea and a potential pest on leguminoseous crops.

The family Psychidae is a small group consisting of 241 genera and 1,350 species in the world. The genus Bacotia, belonging to the family Psychidae, what was established by Tutt based on the type species, Fumea sepium Speyer and Speyer, 1846. In this study, we aimed to record lichen-feeding bagworms in Korea. The genus Bacotia Tutt is reported for the first time from Korea with one newly recorded species, Bacotia sakabei Seino, 1981. All available information, including the collecting localities, host plants, illustrations of adults and genitalia are presented. A DNA barcode for precise identification of the species is also described.

In the present study, one species of the subfamily Doryctinae, Spathius depressithorax Belokobylskij, 1998, is reported for the first time from Korea. A diagnosis and photographs for the species are provided. Also, a total of 13 species of the genus Spathius Nees, 1819 known from Korea is presented with synonymies and distributional ranges.

While conducting a floristic study of Korean moss, we discovered one unrecorded species collected from Mt. Hallasan in Korea. Brachydontium olympicum (E. Britton) T. T. McIntosh & J. R. Spence is recorded for the first time for Korea. Unlike other species of Brachydontium, this species has no peristome and its distal laminal cells are mostly isodiametric.

The vegetative and male reproductive anatomy of a marine alga, Laurencia intercalaris sp. nov. (Rhodomelaceae, Rhodophyta), is described from subtidal habitats of eastern and southern Korea. This species has terete thalli with entangled fibrous holdfasts and regularly alternate branching of ultimate branchlets, and is inseparable from L. okamurae Yamada on the basis of habit. Vegetative axial cells produce a trichoblast and four pericentral cells in an alternating sequence. Spermatangia are produced intercalary or subterminally from one of two laterals on suprabasal cells of trichoblasts arising from axial cells in apical pits of branchlets. The other lateral remains sterile. In this sterile lateral, budding-like regeneration occurs on older segments that are oabscised. Comparison is made with other related Laurencia species, particularly those with terete thalli. The vegetative anatomy and the regeneration in sterile laterals of male trichoblasts, with the mode of spermatangial formation, distinguish the new species from previously described species of Laurencia including L. okamurae.

The Apiaceae genus Daucus consists of approximately 25 species (including carrots) which are characterized by the presence of bracts in pedunculate umbels, dorsally compressed mericarps, hairs on primary ridges, and uniseriately arranged spines on the secondary ridges of the fruit. Taxonomically, Daucus has been considered to be one of the most problematic genera in the Apiaceae due to the highly variable fruit morphology. Despite taxonomic controversy and economic importance of the genus, no rigorously constructed estimate of phylogenetic relationships exists. To examine generic limit and relationships among species of Daucus and its putatively related taxa, phylogenetic analyses of characters derived from nuclear ribosomal DNA ITS sequences were conducted. Two major clades emerged within Daucus, but neither of them have been previously recognized using morphological characters. The phylogeny also provides taxonomic status of recently reported new species of Daucus, D. arcanus and D. conchitae.
