- Using only 24 taxa for which both 18S rDNA and actin sequences are currently available, phenetically aligned data (length = 7243) placed Colpodella and Perkinsus species as sister taxa to Ciliophora, and Dinoflagellata, respectively. Identical results (fig 2C) were found with the phylogenetically aligned data (length = 7176). The latter result was strongly supported by parsimony jackknifing and 38 to 40 extra steps were re- the absence of any unambiguous synapoquired to make the genera Colpodella and morphies'' since they considered micropores Perkinsus monophyletic.
