1. Australocirrus australis ( Foissner, 1995) Kumar and Foissner, 2015 ( Figs. 1 A-C)

Diagnosis. Size about 160-195 × 55-95 μm from protargol impregnated specimens, body shape elongate ellipsoid or slightly obovate; contractile vacuole slightly above mid-body at left margin of cell, with two long collecting canals; two macronuclear nodules ellipsoidal; two to six micronuclei; anterior pretransverse cirrus to anteriormost transverse cirrus length about 1.4% of body length; five or six transverse cirri arranged oblique row; left marginal row 34-42 and right 30-37 cirri; adoral zone composed of 43-54 membranelles extending to 31- 42% of body length; usually 11 (9-11) dorsal kineties.

Material examined. Moss-covered soil from Mt. Dutasan , Jinbu-myeon, Pyeongchang-gun, Gangwon-do, Korea (37°35 ʹ 49.37 ʺ N, 127°34 ʹ 18.50 ʺ E), May 28, 2017. Voucher slides. A slide of protargol-impregnated specimens was deposited at the National Institute of Biological Resources, Korea (NIBRPR0000107959) .

Remarks. Australocirrus australis is very similar to A. shii in body size, number of adoral membranelles, number of cirri in right and left marginal rows, and number of dorsal kineties. However, they can be distinguished from the percentage of the distance between the anterior pretransverse cirrus and the anteriormost transverse cirrus relative to body length (5-8% vs. 0.6-2.1%), and the arrangement of the transverse cirri (3 + 2 vs. an oblique row) ( Foissner, 1995; Kumar and Foissner, 2015).
