A study on indigenous diatoms was carried out at 10 sites from May 2014 to December 2016 in marine and freshwater in Korea. Seventeen species of diatoms are new to Korea and they are divided into 3 classes, 4 subclasses, 10 orders, 14 families, and 16 genera. The nomenclatures, references, dimensions, specimens examined, local habitat, distribution in Korea, and photograph are reported here. Seventeen species found in marine, freshwater, and brackish water showed species-specific habitats.

Four species of the families Gnaphosidae and Clubionidae are reported. Cladothela unmunensis n. sp. is described from Gyeongsangbuk-do, Korea. Drassodes longispinus Marusik and Logunov, 1995, Gnaphosa inconspecta Simon, 1878 and Clubiona tongdaoensis Zhang, Yin, Bao and Kim, 1997 are newly recorded to the Korean spider fauna.

In this paper, two species of Mirine plant bug, Polymerus amurensis Kerzhner, 1988 and Rhabdomiris striatellus Fabricus, 1794 are newly recorded from Korean peninsula. The dorsal habitus and genital structure of each species were provided. Also, figure of related species, P. pekinensis Horvath, 1901 and R. pulcherrimus Lindberg, 1934 were also documented to aid in the identifications of newly recorded species respectively.

Aphidiinae in Braconidae includes more than 400 species within approximately 60 genera worldwide. Species of Aphidiinae are mostly known as solitary koinobiont endoparasitoids specifically associated with aphid hosts, and some of them are used for biological control. In the present study, two aphiniine species are newly recognized from South Korea based on morphological and molecular study: Aphidius rhopalosiphi de Stefani-Perez 1902 and A. uzbekistanicus Luzhetzki 1960. Although It was very difficult to discriminate two species morphologically, we cleary identified them by using COI (cytochrome c oxidase subunit I) DNA Barcode sequences. Here we present their morphological descriptions, illustrations and barcoding results.

Entomacis, a moderately sized parasitic wasp genus within Diapriidae, consist of 56 species in the world. In East Asia, 11 species are recorded from Japan, 6 species from South Korea and Russia and 4 species from China. In this study, two newly recorded species of the genus Entomacis Förster, 1856 (Hymenoptera: Diaprioidea: Diapriidae), E. laticeps Chemyreva, 2015 and E. penelope Nixon, 1980, are reported from South Korea. A revised identification key to the South Korean species, diagnosis, illustrations and photographs of the diagnostic characteristics are provided herein

The subfamily Iassinae Walker belongs to the family Cicadellidae (Hemiptera: Auchenorrhyncha). A total of 124 genera with 1,999 species have been described in the world. To date, two genera, Batracomorphus Lewis and Iassus Fabricius, and 5 species of the subfamily have been recorded in Korea. In this talk, one new species and one new record of the genus Batracomorphus and one new species and two new records of the genus Iassus from Korea are presented. And we also provide biological information such as host plants and distributional records of the Korean Iassine species.

Suborder Psocomorpha belongs to Psocoptera is one of minor order. Psocids occupy a wide range of habitats, from living as indoor, if outdoor most are presented on bark or foliage of dead or leaving tree and shrubs. All specimens of Psocomorpha that found in the field were putted into 75% of alcohol. Preparation and dissection were done before identification. Previously the list of Psocomorpha comprised 14 species. This most recent collection found nine species. Among of them, two species belong to two families; [Amphipsocidae] Amphipsocus japonicas (Enderlein, 1906) and [Psocidae] Psococerastis tokyoensis (Enderlein, 1906) are report in Korea in the first time.

The genus Trissolcus Ashmead is an egg parasitoid of the family Pentatomidae, of which species are used for biocontrol agents for sting bug pests. Until now, 8 species of Trissolcus were recorded from South Korea. In this study, two species, Trissolcus plautiae (Watanabe) and T. elasmuchae (Watanabe, 1954), are newly recognized from Korean peninsula. Diagnosis, photographs and key to species are provided.

A survey was carried out to investigate Gamasina mite composition in the Gyeongbuk and Gangwon, during 2009-2014. Samples were collected from wide range of habitats (i.e. forest, riparian grassland, agriculture). 3 species namely Antennoseius avius (Ascidae), Hypoaspis sardous (Laelapidae) and Stylochirus caucasicus (Ologamasidae) are records as new records compared to already existed database of mite in Korea. Description of three new records species, identification keys (female adult) each species and figures of external morphology are given.

Family Tineidae belongs to the superfamily Tineoidea, with about 2,500 species belonging to 450 genera all over the world (Robinson, 2009). Adult are usually very small to medium-size, 5-20 mm in the wingspan. Larvae feed on fern, lichens, fungi, animal detritus such as feathers, skin and fur and on vegetable matter. In Korea, family Tineidae is reported 7 subfamilies, 26 species (Korean Checklist, 2009), while in Japan reported 13 subfamilies, about 60 species (Hirowatari et al., 2013). In the present study, the species of Korean tineidae are reviewed, with their life cycle, habitat, and food-sources such as keratin materials. We collect that and rear in the rearing cage. Main target of this research is subfamily Tineinae, and is larvae feed on a variety of substrates that contain either keratin or chitin sources such as feathers, fur, pellets, arthropod remains, guano, and wool. In this study we recognized 36 species including 4 newly recorded from Korea for the first time.

The bdelloids collected from various terrestrial habitats such as mosses, lichens, mushrooms on tree trunks, leaf litter and soil at four different locations in Korea were investigated. Five bdelloids new to Korea were identified: Macrotrachella inermis Donner, 1965, Macrotrachela magna Schulte, 1954, Macrotrachela oblita Donner, 1949, Habrotrocha eremita (Bryce, 1894) and Habrotrocha schultei Donner, 1965. All these rotifers except M. inermis are new to Asia as well. Remarkably, these five Korean new records included four rare species with poorly known distributions. M. magna and H. schultei are recorded outside their type localities for the first time. M. oblita has been reported only from five European countries, and M. inermis has been known from three European countries and Eastern Turkey before the present study. The taxonomy and distribution of each rare bdelloid are discussed here.

We verified three ciliates - Dysteria brasiliensis Faria et al., 1922, Dysteria lanceolata Claparède and Lachmann, 1859, and Dysteria ovalis (Gourret and Roeser, 1886) Kahl, 1931 - as previously unrecorded species in Korea. These three ciliates were collected from Incheon Harbor and Geojin Harbor in Korea. We describe the three species based on live observations, protargolimpregnated specimens, and silver nitrate-impregnated specimens.

The oligochaete worms in the genus Nais are common to freshwater habitats. These worms have a highly-developed prostomium and pigmented eye spots. All species have hair chaetae, bifid or single pointed needle chaetae on the dorsal side and ventral chaetae beginning in II with bifid crotchets. Most species of Nais genus live in areas where bottom is covered by sand, gravel or organic matter in aquatic plants. Currently, 26 species of Nais have been recorded worldwide. From the recent faunal studies, 3 species of Nais have been newly reported in Korea. Here, we newly report 6 species of Nais with diagnosis, illustrations and identification keys to Korean Nais species: N. behningi, N. pseudobtusa, N. simplex, N. bretscheri, N. stolci and N. elinguis.

The rotifers collected from various terrestrial habitats such as mosses, lichens and mushrooms on tree trunks at four different locations in Korea were investigated. Five species and one subspecies belonging to four genera in three families of monogonont and bdelloid rotifers were identified: Adineta cuneata Milne, 1916, Macrotrachela insolita De Koning, 1947, Macrotrachela musculosa Milne, 1886, Macrotrachela nana nana (Bryce, 1912), Mniobia bredensis De Koning, 1947 and Bryceella stylata (Milne, 1886). All these rotifers are new to Korea, and A. cuneata, M. bredensis and B. stylata are new to Asia as well. Here diagnostic characteristics and illustrations are provided for each Korean new record.
