During a pluri-disciplinary study carried out within
the frame of the Spanish research project DOS MARES,
multicore samples were collected along the Blanes submarine
canyon and its adjacent open slope to study the structure and
dynamics of the meiofaunal organisms, mainly nematodes.
Among the 5808 nematode individuals identified, only 190
of them belonged to the genus Tricoma (Desmoscolecidae),
and only two harboured epibiont suctorian ciliates. The three
specimens were located near the tail of the basibionts. A careful
examination of the ciliates revealed that they were suctorians,
which are here described as a new species of
Loricophrya, namely L. mediterranea sp. nov. The new species
is characterized by having a conical, slightly elongated
lorica, narrowing towards posterior end; an anterior end inward
curved, surrounding the lorica opening; a body placed
near the lorica opening, occupying 1/3 of the lorica length, 4–
8 capitate tentacles, and a peripheral, oval to sausage-shaped
macronucleus. Our findings represent the first known report of
an association with a deep-sea species of Tricoma, and the first
record in the Mediterranean Sea, for a species of Loricophrya.
The significance of the relationships between suctorian ciliates
and their host in extreme environments such as deep-sea
submarine canyons is discussed.
