New records of nine ciliates (Protozoa: Ciliophora) from Korea: Brief descriptions and remarks Author Min, Kang-San Kim and Gi-Sik mingisik@inha.ac.kr text Journal of Species Research 2018 7 4 315 322 journal article 10.12651/JSR.2018.7.4.315 2713-8615 13161307 8. Leptopharynx costatus gonohymen Omar & Foissner, 2012 ( Fig. 8 ) Material examined. Soil sample taken from Wangsan-ri , Jung-gu , Incheon , South Korea ( 37°26 ʹ 47 ʺ N 126°23 ʹ 40 ʺ E ) on February 2018 . Diagnosis. Cell size 30-40 × 28-35 μm in protargol preparations; 9 somatic and 4 preoral ciliary rows with an average of 183; 2 contractile vacuole; kinety 1 consisting of widely spaced dikinetids; adoral membranelle 1 absent; membranelles 2 and 3 right-angled to each other. Remarks. Omar and Foissner (2012) found the uniqueness of the Floridian population within the Leptopharynx costatus and suggested its subspecies, L. costatus gonohymen . Leptopharynx costatus gonohymen can be distinguished from L. costatus costatus by the numbers of dikinetids (7-8 vs. 11-15) and monokinetids (1 vs. 0-2) in kinety 1, while the Korean population has 7 dikinetids and 1 monokinetid in kinety 1 ( Fig. 8D ) ( Omar and Foissner, 2012 ).

(D) Arrow indicates monokinetid in kinety 1, and arrowheads mark adoral membranelles. Scale bar = 20 μm. Fig. 9.

Two voucher slides with protargol-impregnated specimens are deposited in the National Institute of Biological Resources in Korea (NIBRPR0000109452, NIBRPR0000109453).
