''Corlissina'' is a genus of
karyorelict ciliates
The ciliates are a group of alveolates characterized by the presence of hair-like organelles called cilia, which are identical in structure to flagellum, eukaryotic flagella, but are in general shorter and present in much larger numbers, with a ...
in the family Geleiidae. Only the type species ''Corlissina maricaensis'' is assigned to this genus.
''Corlissina'' is characterized by a paroral ciliature with two rows of polykineties forming a loop at the posterior end. The dikinetids of the adoral zone are organized in short polykineties, followed by a row of monokinetids. The two globular macronuclei are linked by a single micronucleus, a pattern found in most Geleiidae.
The genus name is a
taxonomic patronym honoring the protistologist John O. Corliss.
