测定了美洲异毛藻和肿腹多足虫小亚基rRNA基因的全序列，分别为1719和1786个核苷酸。通过与其他纤毛虫的比较，得出了C. inflata与nassophorean和oligohyphorean的亲缘关系比spirotrichs更近。这与在Copodea类中的Colpodids的位置一致。Blepharisma americanum没有被归类为hypotrichs，而是作为最早的分支纤毛虫。B的明显分离。americanum支持基于形态特征的异毛类地位的提升。
The complete small subunit rRNA gene sequences of the heterotrich Blepharisma americanum and the colpodid Colpoda inflata were determined to be 1719 and 1786 nucleotides respectively. The phylogeny produced by comparisons with other ciliates indicated that C. inflata is allied more closely with the nassophoreans and oligohymenophoreans than the spirotrichs. This is consistent with the placement of the colpodids in the Class Copodea. Blepharisma americanum was not grouped with the hypotrichs but instead was placed as the earliest branching ciliate. The distinct separation of B. americanum supports the elevation to class status given the heterotrichs based on morphological characters.
