Tintinnopsis cylindrica
Diagnosis
Diagnosis_Genus: Genus name is derived from type host genus, Tintinnopsis, and the Greek phaein (-phagos) meaning eat (-eating) and is Latinized in the masculine to imply tintinnid eater.
Diagnosis_Species: Lorica on average 150-240 μm long and 45-50 μm wide orally, with agglutinated particles; Pasteur pipette-shaped, viz., cylindroidal for on average 65-75% of total length, posteriorly tapered, merging into straight cylindroidal process ~ 20 μm long and 10-15 μm wide. Cell on average 125-210 × 40-45 μm and elongate obconical, highly contractile. 2 macronuclear nodules and 2 micronuclei. Ventral kinety commences anterior to right ciliary field, consists of ~ 36 monokinetids. On average 11 kineties in right and 10 in left ciliary field, all composed of monokinetids and one anterior dikinetid, except for second and third ciliary row with two anterior dikinetids. About 36 dikinetids in
dorsal kinety and 26 in posterior kinety, with a cilium only at each posterior basal body. Lateral ciliary field composed
of ~ 11 monokinetidal kineties. On average 22 collar membranelles of which 4 extend into buccal cavity; single buccal membranelle. Marine and brackish waters.

Type illustration / Type locality / Type specimen
Type material: Neotypified from plankton of the mixo-polyhaline basin (54°32'58'' N, 08°52'59'' E) in the Beltringharder Koog, as (i) no type material is available, (ii) the original description lacks many morphologic features, and (iii) the species has several proposed subjective synonyms.
