Fig. 16 in Integrative taxonomy of five astome ciliates (Ciliophora, Astomatia) isolated from earthworms in Central Europe

Fig. 16. Alignment of variable positions of the 18S rRNA gene of five astome ciliates isolated from the lumbricid earthworms. Boxes mark 25 nucleotide positions in which M. lumbrici (Dujardin, 1841) differs from M. varians (de Puytorac, 1954). The comparison with three outgroup species of Anoplophrya Stein, 1860 indicates that 19 out of the 25 variable nucleotide positions of M. lumrici are either plesiomorphies or possibly homoplasies.
