de Puytorac et al., 1974
Right oral polykinetid composed of few to
many somewhat disordered rows (reduced to a
single row of dikinetids in some genera); left oral
polykinetid composed of several to many
monokinetidal rows ; some with special somatic
cilia in a groove, directing food to oral cavity;
stomatogenesis merotelokinetal in reproductive
cysts (Fig. 1); seven families .
