1. Gonostomum kuehnelti Foissner, 1987 View in CoL ( Fig. 1 View Fig )

Material examined. Terrestrial moss collected from Mt. Odaesan , Odaesan-ro , Jinbu-myeon , Pyeongchang-gun, Gangwon-do, Korea (N 37°43 ʹ 53.2 ʺ, E 128°35 ʹ 23.4 ʺ) on 28 April 2018 GoogleMaps .

Diagnosis. Size in vivo 70 - 110 × 20 - 35 μm and 65 - 95 × 19 - 30 (n = 11) after protargol impregnation. Body ellipsoid to elongate ellipsoid with both ends narrowed and margins parallel. 15 - 23 macronuclear nodules usually arranged in two groups. Cortical granules rod-shaped, colorless, and 0.5 × 1 μm in vivo. Cytoplasm colorless. Adoral zone of membranelles about 45% of body length and composed of 25 - 29 membranelles. Three frontal cirri, single buccal cirrus, frontoventral row III with only one cirrus posterior to right frontal cirrus, frontoventral rows IV and V and frontoterminal row each consist of two cirri. Two pretransverse and two transverse cirri near cell end. Right and left marginal row composed of 22 - 26 and 16 - 19 cirri, respectively. Three dorsal kineties each ends with a single caudal cirrus.

Distribution. Antarctica, Austria, Germany, India, Italy, Kenya, Slovakia, Turkey, and Korea.

Remarks. Gonostomum kuehnelti is unique within the genus in having a higher number of macronuclear nodules arranged in two groups. The Korean population of G. kuehnelti fits the description of the type ( Foissner, 1987), the Indian ( Kamra et al., 2008), and the Chinese ( Ning et al., 2019) population but differs mainly in the higher number of macronuclear nodules (15 - 23 vs. 10 - 17, 13 - 19, and 7 - 16, respectively).

Voucher slides. One slide with protargol-impregnated specimens were deposited at the Nakdonggang National Institute of Biological Resources (NNIBRPR11674).
