“…Consequently the validity of A. oligonucleata awaits further support. The organism reported as A. clarissima by Ricci, Santangelo & Luporini (1982) has only nine macronuclear nodules and therefore is probably a population of A. oligonucleata if this is a valid species ( Fig. 5G; Table 2).…”

The morphology and phylogeny of three heterotrich ciliates, Anigsteinia clarissima (Anigstein, 1912) Isquith, 1968, Blepharisma penardi sp. nov., and Blepharisma undulans Stein, 1867, were investigated based on living morphology, infraciliature, and small subunit (SSU) rDNA sequence data. The new species B. penardi sp. nov. is recognized by the following combination of characters: size about 150-180 × 45-55 μm in vivo, cell colour variable from colourless to pale pink to dark brownish; peristome extending to middle of body; 36-63 adoral membranelles; 24-34 somatic kineties; single macronucleus; cortical granules tiny and colourless; freshwater habitat. Anigsteinia clarissima and B. undulans are both reported from China for the first time and are redescribed based on a combination of previous descriptions and new data from the Chinese populations. Phylogenetic analyses based on SSU rDNA sequence data show that B. penardi sp. nov. and B. undulans are both located within a clade comprising only congeners, thus supporting the monophyly of the genus Blepharisma. Anigsteinia clarissima clusters with its only congener forming a clade that is sister to the Spirostomum assemblage. Both the morphological and the molecular data support the placement of Anigsteinia in the family Spirostomidae.

“…Condylostoma arenarium Spiegel 1926 is a marine species with a broad distribution (Al-Rasheid 1999;Borror 1963;Burkovsky 1970;Dragesco 1960Dragesco , 1965Dragesco and Dragesco-Kern eis 1986;Hartwig 1974;Kattar 1970;Raikov 1963;Ricci et al 1982;Wright 1983). The original description of C. arenarium was solely based on in vivo observations, and the author provided few details on the morphology of this species.…”

Details on Condylostoma arenarium infraciliature have not been described; therefore, it is considered a poorly known species. The lack of detailed description on C. arenarium morphology caused several misidentifications that have accumulated in the literature. In this study, we present the first complete description of C. arenarium infraciliature based on protargol-impregnated organisms and scanning electron microscopy. We also have inferred the phylogenetic position of this species based on 18S rRNA sequences. The main characteristics of C. arenarium population from Guanabara Bay are as follows: in vivo elongated body shape with 350-600 μm length × 70-220 μm width, they are highly contractile when subjected to disturbances, green-yellowish cortical granules are present, contractile vacuoles absent, V-shaped peristome comprises approximately 1/5 of the total length, adoral zone with 83-145 membranelles, 1-2 small frontal cirrus observed only in impregnated specimens, 10-15 fiber-like stripes arranged transversely on the inner wall of the oral cavity, 30-45 somatic kineties, moniliform macronucleus with 15-20 nodules. Some observations on morphogenesis of C. arenarium were also included. In phylogenetic analyses, C. arenarium clustered with Condylostoma sp. within a clade composed of three C. curva sequences with high support values.

“…Later another three species were discovered: C. mononucleata, C. minuta and C. chesapeakensis (Dragesco, 1963;Dragesco, 1965;Small and Lynn, 1985). Of these forms, C. vermiformis is 'well-known' and has been isolated and described by several authors from different geographic locations on both sides of the Atlantic Ocean though the morphology and the infraciliature have never been thoroughly studied (Borror, 1963;Hartwig, 1980;Ricci et al, 1982;Fenchel et al, 1995;Al-Rasheid, 2001;Dragesco, 2002).…”

The living morphology and infraciliature of a marine ciliate, Cardiostomatella vermiformis isolated from a sand beach of the Jiaozhou Bay near Qingdao, China, were investigated by live observation, protargol and silver carbonate impregnation methods. Both the morphological and morphometric data largely agree with former records. Based on the data obtained, an improved diagnosis for Cardiostomatella vermiformis is supplied: Large marine Cardiostomatella with cylindrical body shape and several prolonged caudal cilia; cells in vivo about (90-500) µm×(30-120) µm; macronucleus beaded; single contractile vacuole caudally positioned; buccal apparatus conspicuously small, genus typical; three to six postoral kineties; 96-130 somatic kineties. This species is recorded for the first time in China.
