Notes

Forty-nine species and three varieties of psammobiotic ciliates have been found in the upper sublittoral sands of the Black sea Bulgarian coast. A new species, Tracheloraphis totevi, is described. Nine species are recorded in the Black sea psammon for the first time (Tracheloraphis discolor, Tr. striatus, Kentrophoros flavum, Geleia tenuis, Helicoprorodon multinucleatus, Pseudoprorodon arenicola, Chaenea psammophila, Loxophyllm vermiforme, and Litonotus elongatus). The composition of the fauna proved intermediate between micro- and mesoporal. The maximum number of specific psammobiotic species inhabits fine, heterogeneous, moderately polluted sand, with modal grain size about 0.25-0.3 mm. Many micro- and euryporal species produce mass populations in this biotop. Distribution of the species observed in other geographical regions of the World ocean is analyzed. Non-specific psammobiotic ciliated proved to be more widely distributed than specific ones.
