In this list-format paper, we present unrecorded species of Korean ciliates (phylum Ciliophora). All species were selected from the final reports of the project: "Discovery of Korean Indigenous Species". This project has been carried out to discover and record various Korean indigenous species since 2006 and is funded by the National Institute of Biological Resources (NIBR). Among the various species, ciliates were a major taxon that was highlighted in this project as a speciose group categorized under Protozoa. This paper contains reports of 38 ciliates (8 classes, 16 orders, 23 families, and 34 genera) observed in Korea during the initial five years of the project (2006-2010).

This is the third series of catalogs reporting on Korean species discovered through the 'Discovery of Korean Indigenous Species'. This catalog includes 22 species of invertebrates, excluding insects. The catalog includes the scientific name, an abridged list of synonyms, collection sites, distribution, diagnosis, and figures for each species. Additionally, we provide the newly assigned Korean name, specimen voucher, and, if available, mitochondrial CO1 or 16S gene sequences of the species listed. All species identified and documented here will be officially listed on the 'National Species List of Korea', a database maintained by the National Institute of Biological Resources(NIBR).

The samples were collected at lowland swamps, reservoirs, mountainous wetlands, and sphagnum bogs from 2012 to 2014. The followings were newly recorded in Korea: two species, three varieties, and one form, including six taxa of the genus Cosmarium. The newly recorded Korean species were Cosmarium bioculatum var. hians, C. bireme, C. pseudobiremum, C. nitidulum var. pseudorectangulare, C. trilobulatum f. retusum, and C. trilobulatum var. depressum. The flora of the genus Cosmarium contains 303 taxa in total in Korea. The specimens were cultured and deposited on the algal culture collection of Kyonggi University (ACKU) and National Institute of Botanical Resources (NIBR).

A study searching for unrecorded and taxonomically undescribed indigenous species has been conducted since 2006. Samples were collected from many sites in coastal waters and offshore in Korea as well as around Jeju Island. Since 2008 we have found 13 unrecorded species belonging to family Diplopsaliaceae, Heterocapsaceae, Kolkwitziellaceae, Protoperidiniaceae and Thoracosphaeraceae. The species are as follows, Preperidinium meunieri (2014), Heterocapsa ovata (2015), H. pseudotriquetra (2015), Diplopsalis lenticula (2008), Protoperidinium abei (2009), P. diabolus var. longipes (2010), P. depressum (synonym: P. parallelum (2008)), P. latispinum (2016), P. punctulatum (2010), P. solidicorne (synonym: P. spinosum (2010)), P. subpyriforme (2010), P. pacificum (2013), Scrippsiella hexapraecingula (2009) (note; The numbers in parenthesis refer to the year that the species was reported as unrecorded indigenous species by National Institute of Biological Resources, NIBR hereafter). Among these, 5 species were described as newly recorded species in Korean waters, and 8 were re-described in this study.

This taxonomic study sought to detect and describe diatom species not yet recorded in Korea. The study was conducted at three islands located off the western coast of Korea, Wido Island near Buan, Wonsando Island near Boryeong and Dekjeokdo Island near Incheon. Diatoms were collected from the bottom, stone, macrophytes and other substrates in water bodies, which are affected by seawater. Fifteen naviculoid taxa are described. Of these, 13 are novel to Korea. The genus Navicula has nine species; Navicula alineae Lange-Bertalot, N. ammophila Grunow, N. cariocincta Lange-Bertalot, N. elegantoides Hustedt, N. longicephala Hustedt, N. normaloides Cholnoky, N. notha Wallace, N. novaesiberica Lange-Bertalot, N. riediana Lange-Bertalot & U. Rumrich. The genus Craticula has four species; Craticula buderi (Hustedt) Lange-Bertalot, C. halophila (Grunow) D.G. Mann, C. riparia (Hustedt) Lange-Bertalot and C. riparia var. mollenhaueri Lange-Bertalot.

To find unrecorded diatom species in the Nakdong River Estuary and Yeongil Bay, bottom sediments in the estuary, and seagrasses in the bay were collected from 12 sampling sites. Eighteen species and four genera are added to the national flora of diatom as newly recorded one. In the Nakdong River Estuary, twelve species are new records to Korea, Martyana atomus (Hustedt) Snoeijs, Pseudostaurosira perminuta (Grunow) Sabbe & Vyverman, Trachysphenia acuminata M. Peragallo, Trachysphenia australis Petit, Fallacia clipeiformis ($K{\ddot{o}}nig$) D.G. Mann, Amphora graeffeana Hendey, Amphora jostesorum Witkowski, Metzeltin & Lange-Bertalot, Amphora ostrearia var. vitrea (Cleve) Cleve, Amphora wisei (Salah) Simonsen, Halamphora eunotia (Cleve) Levkov, Halamphora lineata (Gregory) Levkov, Nitzschia littorea Grunow. In Yeongil Bay, four species are added as new, Licmophora gracilis var. anglica ($K{\ddot{u}}tzing$) H. Peragallo & M. Peragallo, Tabularia investiens (W. Smith) Williams & Round, Nitzschia composita Giffen, Nagumoea neritica Witkowski & Kociolek. Two species occurred simultaneously in both regions, Fragilaria cassubica Witkowski & Lange-Bertalot and Hyalinella lateripunctata Witkowski et al.

A single juvenile of the jawfish Stalix toyoshio (24.0 mm standard length) was collected from the South Sea of Korea at a depth of 135 m during box-corer sampling. The specimen was characterized by the absence of stripes on both the body and vertical fins, well-developed cephalic pore systems, yellowish body and fins, six transversely-forked dorsal fin spines, and five mandibular pores. Here, we describe the specimen, which represents the first record of S. toyoshio from Korea and the second record from the northwestern Pacific.

Mite of the genus Hypoaspis of family Laelapidae are free-living soil predators mostly observed on the open grass field. Five species in the genus Hypoaspis were listed in Korean Catalog (NIBR, 2013) without detail information. Recent series of soil acarine biodiversity survey in Gyeongbuk and Gangwon provinces during 2009-2015 recovered a new record of Hypoaspis sardous (Canestrini, 1884) to Korean inventory from apple orchard and riparian grass land. Detailed description and morphological comparison with the related species, H. aculeifer which is well known biological control agent of horticultural crop pests were provided with identification keys.

A study describing unrecorded and taxonomically undescribed indigenous species is in progress since 2006. Samples were collected from many sites in coastal waters and offshore of Korea as well as from Jeju Island. Since 2008, we have found ten unrecorded species of four genera belonging to family Dinophysaceae, Gonyaulacaceae, Gymnodiniaceae, and Heterocapsaceae. The species are as follows, Dinophysis elongata (2016 winter), D. nasuta (2016 winter), Gonyaulax alaskensis (2016 winter), G. diegensis (2017), G. monospina (2008), Amphidinium flagellans(2017), Heterocapsa circularisquama (2017), H. horiguchii (2017), H. lanceolata (2017), and H. pygmaea (2017) (note; The numbers in the parenthesis refer to the year in which the species was reported as unrecorded indigenous species by National Institute of Biological Resources, NIBR hereafter). Among them, seven species were described as newly recorded species in Korean waters, and three have been re-described in this study.
