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 4. Amphisiella australis Blatterer & Foissner, 1988 ( Fig. 4 ) Material examined. Soil sample taken from Bangeo-dong , Ulsan , South Korea ( 35°28 ʹ 56 ʺ N , 129°25 ʹ 54 ʺ E ) on November 2015 . Diagnosis. Cell size in protargol preparations 95-110 × 30-35 μm, flexible, elliptical; adoral zone about 26% of body length, 22-25 adoral membranelles; contractile vacuole at slightly ahead of mid-body near left cell margin; 2 macronuclear nodules with 2 or 3 micronuclei; 3 frontal cirri; 3 or 5 cirri in left of anterior end of amphisiellid median cirral row; 13-15 cirri in amphisiellid median cirral row; 1 buccal cirrus; 5 or 6 transverse cirri; 1 left (37-40 cirri) and 1 right (41-43 cirri) marginal cirral row; 3 dorsal kineties; caudal cirri lacking. Remarks. Morphologically, Amphisiella australis is most similar to Lamtostyla australis , although they are assigned to different genera. Lamtostyla australis differs from Amphisiella australis by the following features: number of transverse cirri (usually 2 vs. usually 5); length of amphisiellid median cirral row (38-46% of body length vs. 50%); shape of undulating membranes (slightly curved vs. distinctly curved); position of buccal cirrus (at anterior end of the paroral vs. distinctly behind the anterior end of the paroral) ( Berger, 2008 ). However, as these features showed ambiguous differences, additional data and molecular phylogenetic analysis are needed clarification. Deposition. One voucher slide with protargol-impregnated specimens is deposited in the National Institute of Biological Resources in Korea (NIBRPR0000109447).
