Frontonia angusta solea (Foissner, 1987) 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. Fig. 15. Photomicrograph of Metanophrys sinensis after protargol impregnation. A, B. Somatic and oral ciliatures. C. Macronucleus and caudal cilium. CC, caudal cilium; M1-3, oral membranelles; MA, macronucleus; PM, paroral membrane. Scale bars =20 μm. 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).
