Ontogeny and Molecular Phylogeny of Apoamphisiella vernalis Reveal Unclear Separation between Genera Apoamphisiella and Paraurostyla (Protozoa, Ciliophora, Hypotricha)
Fig 19
Diagram showing homologies among ventral cirri of Cyrtohymena, European and North American Paraurostyla weissei, and Apoamphisiella on stylized drawings.
*The rightmost ventral cirral row of European P. weissei corresponds to the posterior segment of an amphisiellid row. Fronto-ventral-transverse anlagen are numbered in romans. IV? = anlage supposedly related to IV; Vi … Vj = serial homology of anlage V, where “i” is the leftmost and “j” the rightmost in the series; aAR = anterior segment of the amphisiellid cirral row; B = buccal; F = frontal; FV = frontoventral; Pp = postperistomal; PT = pretransverse; T = transverse; VR = ventral cirral row; - = inapplicable.
