Abstract

Two rare ciliates from soil under the oak tree and mosses in the top of mountain in Korea were identified as Gonostomum algicola Gellert, 1942 and G. gonostomoida (Hemberger, 1985), respectively. There is little information on their morphological features, therefore their detailed redescriptions are needed. The description was based on the observation of living and protargol impregnated specimens, and biometric analysis. Their diagnostic characteristics are as follows. Gonostomum algicola; $88-113\times30-40{\mu}m$ in vivo, colourless cortical granules, 20-31 adoral membranelles, two fronto-terminal cirri, five fronto-ventral cirri, no mid-ventral cirri, two transverse cirri, two to three micronuceli. Gonostomum gonostomoida; $60-121\times21-40{\mu}m$ in vivo, no cortical granules, 27-34 adoral membranelles, no fronto-terminal cirri, two fronto-ventral cirral rows with each row bearing three cirri, midventral cirral row with 11-14 cirri, two to three transverse cirri, one to six micronuceli. So far, total three species within the genus Gonostomum have been recorded from Korea by the present study.
