11. Periholosticha paucicirrata Foissner, Berger, Xu and Zechmeister-Boltenster, 2005 ( Fig. 2C )

Diagnosis: Body size 70 × 10 μm in protargol preparations; body shape very narrowly elongated, flattened dorsoventrally; flexible. Nuclear apparatus composed of ca. 15 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, two frontoterminal cirri, four midventral cirral pairs, one left and one right marginal cirral row.

Remark: It is first record of the genus Periholosticha from Korea. They have roughly elongated body shape (Berger, 2006). Of the morphologically related congeners, Periholosticha lanceolata differs from P. paucicirrata mainly by the number of dorsal kineties (Berger, 2006).

Voucher slides: Two slides including protargol­impregnated specimens have been deposited in the National Institute of Biological Resources in Korea (NIBRPR0000 107120, NIBRPR0000107121).
