Cothurnia ceramicola Kahl, 1933  

( Fig. 3 View FIGURE 3 D-2, E; 4 C, D)

Brief description: Marine loricate peritrich ciliate. Lorica, rounded posteriorly with short external stalk, endostyle and short, broad, longitudinally striated mesostyle. There are one or two zooids in the lorica, which extending up to one third of its length beyond aperture. The pellicula of zooids conspicuously striated. Macronucleus band-like, long.

Measurements (in μm, based on two individuals): Lorica length 65–90 (65–77 after Warren & Paynter 1991); lorica width 18–27 (30 after Warren & Paynter 1991); contracted zooid length 38–37; contracted zooid width 14–17; external stalk length 4–19; external stalk diameter 2; endostyle length 5; endostyle width 5; mesostyle length 3; mesostyle width 4.

Remarks: This species was firstly described as an epibiont of the alga Ceramium   sp. in the Kiel bay, the Northern Sea ( Kahl 1933, 1935). It was also found on bryozoans Crisia burnea (Linnaeus, 1758)   and Cribilina punctata (Hassall, 1841)   , the polychaete Spirorbis spirorbis (Linnaeus, 1758)   , and the hydrozoan Gonothyrae aloveni (Allman, 1859) ( Precht 1935). Later this species was also reported by Felinska (1965) attached to algae collected near Plymouth, UK.

The Ciliate Cothurnia ceramicola   was attached on stalk ( Fig. 3E View FIGURE 3 ) as well on zooidal dilatations ( Fig. 3 View FIGURE 3 D-2) of Triticella pedicellata   . This is the first record of this species from the Arabian Sea and Indian Ocean.
