Morphology and Phylogeny of Four Marine Scuticociliates (Protista, Ciliophora), with Descriptions of Two New Species: Pleuronema elegans spec. nov. and Uronema orientalis spec. nov.

Abstract

The morphology and infraciliature of four marine scuticociliates, Pleuronema elegans spec. nov., P. setigerum Calkins, 1902, P. grolierei Wang et al., 2008 and Uronema orientalis spec. nov., collected from China seas, were investigated through live observation and protargol staining methods. Pleuronema elegans spec. nov. can be recognized by the combination of the following characters: size in vivo 90–115 × 45–60 µm, slender oval in outline with a distinctly pointed posterior end; about 10 prolonged caudal cilia; consistently two preoral kineties and 18 or 19 somatic kineties; membranelle 2a double-rowed with its posterior end straight; membranelle 3 three-rowed; one macronucleus; marine habitat.Uronema orientalis spec. nov. is distinguished by the following features: in vivo about 40–55 × 20–30 μm with a truncated apical plate; consistently twenty somatic kineties; membranelle 1 single-rowed and divided into two parts which comprise four and three basal bodies respectively; contractile vacuole pore positioned at the end of the second somatic kinety; marine habitat. We also provide improved diagnoses for P. grolierei Wang et al., 2008 and P. setigerum Calkins, 1902 based on current and previous reports. The small subunit rRNA gene of U. orientalisP. elegansP. grolierei and P. puytoraci were sequenced. Phylogenetic analyses indicate that Uronema and Pleuronema are not monophyletic.
