2. Rimaleptus longitrichus (Vd̓ačný and Foissner,

2008) Vd̓ačný and Foissner, 2012 ( Figs. 1 D-G)

Diagnosis. Size about 240 × 30 μm in vivo; narrow to cylindroida dileptid shape with rounded posterior end, dorsally curved anterior end, proboscis about 30% of body length; contractile vacuoles located both ventral and dorsal sides; extrusomes rod-shaped; ciliary rows 20 or 21, longitudinal rows anteriorly spaced, dorsal brush composed of two rows; two macronucleus nodules, oblong shape and 1or 2 micronuclei between macronuclear nodules.

Material examined. From soil at Ilchulam , Pohang-si, Nam-gu, Gyeongsangbuk-do, Korea (35°53 ʹ 48.26 ʺ N, 129°31 ʹ 33.12 ʺ E), February 23, 2016 .

Voucher slides. A slide of protargol-impregnated specimens was deposited at the National Institute of Biological Resources, Korea (NIBRPR0000107957).

Remarks. Rimaleptus longitrichus was originally described by Vd̓ačný and Foissner (2008). It can be distinguished from congeners by the presence of a row of contractile vacuoles on either margin of ventral and dorsal sides (Vd̓ačný and Foissner, 2008; 2012).
