Foissner, Agatha & Berger, 2002 ( Fig. 14 )

Material examined. Temporal pond on a lawn in Gangneung-Wonju National University , Jukheon-gil 7, Gangneung-si, Gangwon-do, Korea (37°46′12.4″N, 128°52′ 16.5″E) on 16 Aug 2019 .

Diagnosis. Size in vivo about 95 × 45 μm (n = 5). Elongate obovate with round anterior end. Single contractile vacuole in mid-body with about 3 excretory pores. Buccal cavity about 20 μm long. About 60 ciliary rows, 3 postoral kineties, and 4 vestibular kineties. Peniculi 1-3 each with 4 rows of basal bodies.

Distribution. Austria, Namibia, and Korea.

Remarks. The Korean F. angusta solea population agrees very well with the Namibian population ( Foissner et al., 2002). It is distinguishable from the most similar subspecies ( F. angusta angusta ) by the smaller size (70-100 μm vs. 90-135 μm in vivo) and the number of somatic kineties (<70 vs.>90).

Voucher slides. Two slides with protargol-impregnated specimens were deposited at National Institute of Biological Resources (NIBRPR0000110215, NIBRPR0000110 216).
