3. Lamtostyla decorata Foissner et al., 2002 View in CoL ( Fig. 3 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 100 - 150 × 20 - 30 μm (n = 3). Body ellipsoid to elongate ellipsoid with both ends round- ed and margins parallel. Two macronuclear nodules and two or three micronuclei attached to macronuclear nodules. Contractile vacuole on left side anterior to mid-body. Cortical granules in groups around cirri, dorsal bristles, and randomly scattered between dorsal kineties, about 0.5 μm in size. Cytoplasm colorless. Adoral zone of membranelles about 20 - 25% of body length. Three frontal cirri, single buccal cirrus, amphisiellid median cirral row consists of two cirri, usually three cirri left and anterior to amphisiellid median cirral row, and two frontoterminal cirri. Two pretransverse and five transverse cirri near cell end. Right and left marginal rows composed of 41 - 46 and 47 - 51 cirri, respectively, anterior portion of right marginal row on dorsal side. Three dorsal kineties. Caudal cirri lacking.
Distribution. Australia, Austria, Namibia, and Korea.
Remarks. The Korean population of L. decorata fits the description of the type population by Foissner et al. (2002). It is also very similar to L. granulifera Foissner, 1997 especially in the number of the right and left marginal cirri (41 - 46 and 47 - 51 vs. 39 - 49 and 42 - 52, respectively). However, this character has proved to be less important because the Korean population (Kim et al., 2016) has slightly overlapping right (34 - 42) and non-overlapping left (33 - 38) marginal cirri. The most important differ- ence between the two species is the arrangement of the cortical granules (groups around cirri, dorsal bristles, and randomly scattered between dorsal kineties in L. decorata vs. inconspicuous and very closely spaced rows on ventral and dorsal side in L. granulifera ) (Foissner, 1997; Kim et al., 2016). Lamtostyla longa ( Hemberger, 1985) Berger & Foissner, 1988 is also similar to L. decorata but differs mainly in having fewer right and left marginal cirri (23 and 21 vs. 44 and 49, respectively) and the number of dorsal kineties (five vs. three).
Voucher slides. One slide with protargol-impregnated specimens was deposited at the Nakdonggang National Institute of Biological Resources (NNIBRPR11675).
