GENUS CLEVELANDELLA KIDDER, 1938

Improved diagnosis: Body posteriorly extended into a medium-long peristomial projection; macronucleus oriented with its longer axis obliquely to main body axis, posterior end of macronucleus typically more or less narrowed; karyophore present, attached to right side below mid-body, in some species also to left body margin; adoral zone of membranelles on right and paroral membrane on left side of vestibulum. Diagnostic molecular characters as shown in Figure 8.

Type species and nomenclature: Clevelandia panesthiae Kidder, 1937 by original designation (Article 68.2 of ICZN, 1999). Kidder (1937) fixed C. panesthiae as type species of Clevelandia Kidder, 1937 (ciliate), which is a junior homonym of Clevelandia Eigenmann & Eigenmann, 1888 (fish). Therefore, Kidder (1938) proposed a new replacement name (nomen novum), Clevelandella , for Clevelandia (ciliate). According to Article 67.7 of ICZN (1999), both the prior nominal genus-group taxon and its replacement have the same type species. Aescht (2001) incorrectly stated that C. panesthiae is a type species of Clevelandella by subsequent designation in Earl (1972).

Etymology: The genus was named in honour of the protistologist L. R. Cleveland.

Figures

Figure 8. Diagram of the morpho-molecular evolution of the family Clevelandellidae based on the present phylogenetic analyses. Molecular diagnostic characters are displayed for each marker in two rows: the upper row refers to the group in question (i.e. query group) and the lower row to the reference group, which includes all remaining clevelandellids and nyctotherids. Numbers correspond to the position of characters in the reference alignments. AZM, adoral zone of membranelles; MA, macronucleus; PM, paroral membrane.
