Fig. 3 Systematic scheme for the phylum Ciliophora suggested by
the present and the previous works .
Fig.2 Hypothetical evolution of ciliated protozoa based on both
morphological and molecular data to show the relationship and
the positions of the taxa at order level. All line drawings of
ciliates are from Corliss (1979), Puytorac (1994), Song and
Wilbert (1989), Vd'acny and Foissner (2002) and present study.
Fig.1 A. Maximum likelihood (ML) trees of the phylum Ciliophora
based on the SSU rDNA (152 taxa). B. Classification scheme of
phylum Ciliophora according to Lynn (2008) and Adl et al. (2012).
 The majority of ciliates are divided into two main
subphyla, Postciliodesmatophora and
Intramacronucleata, based on both morphology
and molecular information.
 Eleven classes are recoganized in the most recent
calssifications (Lynn 2008 and Adl et al. 2012).
 A potential new class Cariacotrichea was
established based on the environmental SSU rRNA,
for a novel clade from the anoxic Cariaco Basin
(Orsi et al., 2011).
 Our recent phylogenetic work suggested two new
classes (Linconophoriea n. cl. , Protocruziea n. cl.)
and one subphyla (Mesodiniea).
