8. Apocoriplites lajacola Oertel et al., 2008 ( Fig. 8 )

Material examined. Terrestrial soil collected from Jibyeon-gil , Gangneung-si, Gangwon-do, Korea (N 37°46 ʹ 26 ʺ, E 128°52 ʹ 15 ʺ) on 26 February 2019 .

Diagnosis. Size about 100 × 30 μm in vivo (n = 3). Body cylindroidal to elongate bursiform. Cytoplasm colorless. Extrusomes lacking. Contractile vacuole terminal. Minute cortical granules arranged in rows between ciliary rows. Two globular macronuclear nodules with a micronucleus in between. 10 - 12 ciliary rows, two anteriorly differentiated into isostichad dorsal brush occupying about 23% of body length and composed of widely spaced dikinetids.

Distribution. Venezuela and Korea.

Remarks. The genera Coriplites and Apocoriplites are characterized by the absence of the extrusomes ( Foissner, 2016). Apocoriplites is a monotypic genus. Thus A. lajacola can be compared only with the species belong to the genus Coriplites , which are characterized by having three brush rows ( Oertel et al., 2008).

Voucher slides. Two slides with protargol-impregnated specimens were deposited at the Nakdonggang National Institute of Biological Resources (NNIBRPR11660, NNI BRPR11661).
