Abstract

Two litonotid ciliates collected from the freshwater habitats in Korea were identified as Loxophyllum meleagris ($M\ddot{u}ller$, 1773) and Siroloxophyllum utriculariae (Penard, 1922). The description was based on the observation of living and protargol impregnated specimens, and biometric analysis. Their diagnostic characteristics are as follows. L. meleagris; $163-480\times80-100{\mu}m$ in vivo, body shape lancet or knife-like; dorsal margin with 10-19 extrusome warts; 8-35 macronuclei nodules, like a string of bead; 16-21 somatic kineties on right side (including perioral kinety 2, 3) and 6-11 on left side (including perioral kinety 1); 1 contractile vacuole located at posterior part at diastole stage, extending along the dorsal margin toward anterior end with a single long narrow canal. S. utriculariae; $110-170\times78-150{\mu}m$ in vivo, body shape lancet like; dorsal margin without extrusome warts; 2 macronuclei, spherical; 12-19 somatic kineties on right side, 3-7 on left side (including perioral kinety 1); 2-3 contractile vacuoles, first one located anterior ventrally, second one located posterior dorsally and last one located near posterior end of cell.
