We identified two soil stichotrichs, Eschaneustyla lugeri Foissner, Agatha & Berger, 2002 and Oxytricha auripunctata Blatterer & Foissner, 1988, which were collected from Sarabong, Jeju and Ajoong-ri, Jeonju in Korea, respectively. Eschaneustyla lugeri had the following characteristics: size in vivo $170-230{\mu}m{\times}40-60{\mu}m$; body elongate elliptical and often very narrow in the posterior region, highly flexible; cortical granules present; 48-67 macronuclear nodules; 27-47 frontal cirri; 3-5 buccal cirri; frontoterminal row and rightmost midventral row; transverse cirri absent; 4 dorsal kineties; 4-9 caudal cirri. Oxytricha auripunctata had the following characteristics: size in vivo $75-95{\mu}m{\times}25-35{\mu}m$; body elliptical, both ends moderately narrowly rounded; orange-yellow cortical granules and yellowish crystals; 3-4 transverse cirri; 5 dorsal kineties; 3 caudal cirri. These two ciliates are first reported in Korea. We describe these ciliates based on live observations and protargol-impregnated specimens.

We firstly report three stichotrichs, Metaurostylopsis cheni Chen, Huang & Song, 2010, Gonostomum strenuum (Engelmann, 1862) Sterki, 1878, and Lamtostyla granulifera Foissner, 1997, collected in South Korea. We investigated these ciliates based on observations of live and protargol-impregnated specimens.

In the present study, the first mitochondrial cytochrome c oxidase subunit I gene (COI) sequence of Sterkiella multicirrata Li et al., 2018 is presented. To begin with, this species has been also morphologically recorded from South Korea, and this study was performed using genomic DNA of the Korean population. The newly obtained COI sequences of S. multicirrata were identical. And the inter-specific variation between S. multicirrata and S. histriomuscorum was noted at 14.3%. These values correspond well with the results of previous studies. However, because there are very few available COI sequences of stichotrichian in GenBank, it is concluded that continuous accumulation of data is needed for further study.

Ten stichotrichid ciliates were identified from six environmental samples, consisting of one freshwater, two seawater, and three soil samples. Morphological assessments were performed based on observations of both living and stained specimens. These species were assigned to two orders, three families, and nine genera, and we provide photographs and brief descriptions and remarks for each species: Parabirojimia similis Hu et al., 2002, Arcuseries warreni (Song & Wilbert, 1997) Huang et al., 2014, Gonostomum lajacola Foissner, 2016, Paragonostomoides xianicum Wang et al., 2017, Australocirrus oscitans Blatterer & Foissner, 1988, Monomicrocaryon crassicirratum Foissner, 2016, Monomicrocaryon euglenivorum fimbricirratum Foissner, 2016, Notohymena rubescens Blatterer & Foissner, 1988, Sterkiella multicirrata Li et al., 2018, Stylonychia ammermanni ammermanni Gupta et al., 2001.

Two stichotrichous ciliates, Amphisiella annulata (Kahl, 1928) and Pseudoamphisiella alveolata (Kahl, 1932), were collected from the Yellow Sea in Incheon, Korea and were identified as new to Korea. The main diagnostic key to the species of the genera are that the two species share the features of two macronuclear nodules, one marginal row per side, and transverse cirri. A. annulata is distinguishable from other members in the genus mainly due to the several ring-shaped (hollow) structures in its cytoplasm and its wide and narrowly arranged amphisiellid median cirral row. P. alveolata has a conspicuous alveolar layer and two conspicuous macronuclear nodules, but no frontoterminal cirri.

The seven unrecorded ciliates were collected from soil samples in Korea. The morphological study of these ciliates was performed based on observation of both living and stained cells: Rigidocortex quadrinucleatus Bharti, Kumar and La Terza, 2017, Rigidohymena tetracirrata (Gellért, 1942) Berger, 2011, Urosoma salmastra (Dragesco and Dragesco-Kernéis, 1986) Berger, 1999, Urosomoida agilis (Engelmann, 1862) Foissner, 1982, Rigidosticha italiensis Bharti, Kumar and La Terza, 2016, Eschaneustyla terricola Foissner, 1982 and Pseudokeronopsis similis (Stokes, 1886) Borror and Wicklow, 1983. Among the seven genera in this study, the genus Rigidosticha Bharti, Kumar and La Terza, 2016 is firstly reported in Korea. In this study, we provide brief descriptions and remarks for the ciliates with photographs.
