Improved description of the bipolar ciliate, Euplotes petzi, and definition of its basal position in the Euplotes phylogenetic tree
2014AbstractData improving the characterization of the marine Euplotes species, E. petzi Wilbert and Song, 2008, were obtained frommorphological, ecological and genetic analyses of Antarctic and Arctic wild-type strains. This species is identified by a minute(mean size, 46 m × 32 m) and ellipsoidal...

This species is identified by a minute(mean size, 46 m × 32 m) and ellipsoidal cell body which is dorsally decorated with an argyrome of the double-patellatype, five dorsal kineties (of which the median one contains 8–10 dikinetids), five sharp-edged longitudinal ridges, and a rightanterior spur.
