( Fig. 2 A–C)

Lecanophryella paraleptastaci Dovgal, 1985, 1256 –1259, Figs. 1–4 .

Diagnosis and dimensions of this species is given here following Dovgal (1985). As Dovgal (1985) was primarily a Russian language description, the present article provides a re-description of diagnosis and dimensions to appraise a wide range of workers.

Diagnosis. Suctorian ciliate with slightly laterally flattened body, equipped with two ( Fig. 2B ), rarely three ( Fig. 2C ) well-developed actinophores, at the extended ends of which positioned groups of the clavate tentacles, which extended at the base. The cell pellicula with well-defined longitudinal folds. Stalk short, dense, slightly curved. Macronucleus is rounded, located medially, or located within one of the actinophores. Reproduction by vermigemmic budding. Swarmers ( Fig. 2A ) are unciliary, leaf-shaped, with a well-developed apical sucker.

Commensal of freshwater harpacticoid copepods. Localization: host body segments.

Dimensions (in µm): body length 36–72, body width 10–36, actinophore length 17–46, tentacle length 9–14, stalk length 7–19, slalk diameted 4–5, size of macronucleus 10–14×5–10. Dimentsons of swarmer: length 36–46, width 19–22, sucker diameter 11–13.

Type material: A hapantotype slide No. 118 deposited in I.I. Schmalhausen Institute of Zoology of National Academy of Sciences of Ukraine ( Kiev, Ukraine) .

Type host: Paraleptastacus spinicauda triseta Noodt, 1954 .

Type locality: Kremenchug water reservoir on the Dnieper River ( Ukraine) .
