2. Peritromus kahli Villeneuve-Brachon, 1940 ( Fig. 2 )

Material examined. Brackish water (salinity 17.4‰) collected from Taehahang Port , Hyeonpo-ri , Buk-myeong, Ulleung-gun, Gyeongsangbuk-do, Korea (37°31 ʹ 24 ʺ N, 130°48 ʹ 52 ʺ E) on 30 August 2018 .

Diagnosis. Body size 50-150 × 40-80 μm in vivo; body broad elliptical to oval shape, strongly flattened dorso-ventrally, whole body folding when stimulated; cytoplasm slightly yellowish; spine-like external cilia surrounded body outline; cortical granules linearly arranged between somatic kineties on ventral side and slightly yellowish; numerous peculiar chalice-like structure densely arranged on whole dorsal side; 2 ellipsoidal macronuclei; 80-93 adoral membranelles; 30-38 somatic kineties.

Distribution. Korea and France.

Remarks. Peritromus kahli differs from the most similar congener, P. faurei Kahl, 1932 , in the absence (vs. presence) of the protrusions on dorsal surface and in the presence (vs. absence) of the peculiar chalice-like structure on dorsal side ( Rosati et al., 2004; Shao et al., 2009).

Voucher slides. One slide with protargol-impregnated specimens was deposited at National Institute of Biological Resources, Korea (NIBRPR0000109479) and one slide was deposited at the National Marine Biodiversity

Institute of Korea (MABIK PR00043127).
