title: New contributions to two heterotrichous ciliates, Folliculina simplex (Dons, 1917), Condylostoma curva Burkovsky, 1970 and one licnophorid, Licnophora lyngbycola Fauré-Fremiet, 1937 (Protozoa, Ciliophora): descriptions of morphology and infraciliature.
abstract: The living morphology and infraciliature of two heterotrichous and one licnophorid ciliates from the north China seas, i.e. Folliculina simplex (Dons 1917), Condylostoma curva Burkovsky, 1970, and Licnophora lyngbycola Fauré-Fremiet, 1937, were investigated using protargol impregnation and in vivo observations. Updated diagnoses and redescriptions of each species are provided. The improved diagnosis of Folliculina simplex is as follows: blue-greyish to blue-greenish Folliculina with broad and unequal-sized peristomial lobes; adoral zone of membranelles comprises about 400 membranelles and forms two-and-half turns within buccal cavity; paroral membrane extends entire length of adoral zone of membranelles; about 50 somatic kineties in mid-body; single ovoid to ellipsoid macronucleus and several micronuclei; lorica vase-shaped, about 150-250 microm long, often with jelly-like covering and inconspicuous neck; marine habitat. Improved diagnosis for Licnophora lyngbycola: marine Licnophora with cup-shaped body and glabrous adhesive disc with which the organism attaches to the filaments of the colourless cyanobacterium Lyngbya; in vivo 80-130 microm long; about 140 adoral membranelles, one micronucleus and a single C-shaped, moniliform macronucleus consisting of about 14 nodules; two specialized dorsal kineties; five peripheral rings on adhesive disc, the 2nd, 3rd, and 5th (outermost) which are incomplete. Based on the Qingdao population, an improved diagnosis for Condylostoma curva is supplied: yellow-brownish Condylostoma with oval to elongated body shape; about 150-350 microm long in vivo; about 68-108 membranelles in adoral zone of membranelles, 4-8 frontal cirri, 22-32 somatic kineties; macronucleus moniliform with 5-13 nodules; with cortical granules; marine habitat.
