Tirjaková, 2006 ( Fig. 2B)

Diagnosis. Body size approximate 65 × 20 μm in protargol preparations; body shape elongated ellipsoidal, flattened dorsoventrally, both body ends rounded with slightly narrow anterior end; flexible. Nuclear apparatus composed of 6 macronuclear nodules and several micronuclei, arranged in a longitudinal row. Cortical granules lacking. Cytoplasm colourless. Movement, without any peculiarities, crawling on soil surface. Cirri pattern, on average, composed of 3 frontal, 2 frontoterminal, 1 buccal, 7 frontoventral, and 4 pretransverse ventral and transverse cirri; 3 dorsal kineties and 2 caudal cirri; paroral membrane composed of 10 kinetids.

Remarks. Gonostomum albicarpathicum can be easily distinguished from congeners by the number of macronuclear nodules (more than two vs. two in the others; Berger, 2011). Three Gonostomum species have been reported in Korea ( Shin and Kim, 1995; Kim and Shin, 2006; Kim et al., 2016): G. affine , G. algicola , and G. strenuum .

Voucher slides. Two slides, including protargol-impregnated specimens (HG), were deposited at the National Institute of Biological Resources in Korea (NIBR PR0000107195, NIBRPR0000107196).
