( Fig. 2 View Fig )
Material examined. Marine water with some debris (salinity, 29.3‰) collected from Hamdeok Beach , Jocheoneup, Jeju-si, Jeju-do, Korea (33°32′36″N 126°39′51″E) on 8 Jun 2019 GoogleMaps .
Diagnosis. Body size in vivo 95-105 × 55-65 μm (n =3); broad elliptical; 1 small and 7 distinct frontoventral cirri with polystyla -arrangement; single contractile vacuole located subterminally; 5 transverse cirri; 4 dorsal kineties; adoral zone of membranelles (AZM) bipartite, AZM1 composed of 4 membranelles; AZM2 composed of 41-45 membranelles, posterior thorn-like projection absent.
Distribution. China, Korea (Type locality is not mentioned).
Remarks. The Korean population of Aspidisca orthopogon corresponds very well to the Chinese population ( Li et al., 2008). They only differ in the absence (vs. presence) of the thorn-like projection in the rear body end. Aspidisca orthopogon is also similar to A. magna in the body size (95-105× 55-65 μm vs. 50-100× 40-80 μm), but can be easily distinguished from this species and other congeners by the enormous posterior adoral zone (AZM2), which is composed of 41-45 membranelles (vs. 12-13 in A. aculeata , 15-18 in A. magna , and 14-21 in A. leptapsis ) ( Li et al., 2008; 2010).
Voucher slides. Two slides with protargol-impregnated specimens were deposited at the National Institute of Biological Resources (NIBRPR0000110192, NIBRPR0000 110193).
