2003 ( Fig. 2B )

Diagnosis: Body size 125 × 25 μm in protargol preparations; body shape elongated ellipsoidal, flattened dorsoventrally, both body ends rounded; flexible. Nuclear apparatus composed of ca. 20 macronuclear nodules with several micronuclei at left mid­body. Cytoplasm colorless. Movement, without any peculiarities, crawling on soil surface. Cirri, on average, composed of three frontal cirri, one buccal cirri, two frontoterminal cirri, fifteen midventral cirral pairs, two pretransverse ventral cirri, two transverse cirri, one left and one right marginal cirral row.

Remark: The genus Anteholosticha is one of the species­rich groups in the class Spirotrichea. More than 40 species belonging to the genus have been described and they are non­monophyletic ( Park et al., 2013). Eight species including A. distyla have been recorded in Korea ( Shin and Kim, 1993; Li et al., 2011; Park et al., 2012; Shin, 2012; Kim et al., 2013; Park et al., 2013).

Voucher slides: Two slides including protargol­impregnated specimens have been deposited in the National Institute of Biological Resources in Korea (NIBRPR0000 107116, NIBRPR0000107117).
