“…Metopus ) are sister taxa to the clevelandellids. This result has been observed previously by others (Hackstein et al 2002; van Hoek et al 1998, 2000). Lynn (2004) has formally recognized this grouping as the Class ARMOPHOREA and attributed the name to Jankowski for his foresight in recognizing the possibility of their common ancestry.…”

“…Our results confirm those of Hackstein et al (2002): the three nyctotherids endosymbiotic in anurans (i.e. N. parvus, N. cor‐diformis , and N. deslierresae ) were closely related and strongly supported as separate from the two species endosymbiotic in arthropods (i.e.…”

“…Lynn (2004) formally recognized this clade as a new class within the phylum. Hackstein et al (2002) used the SSrRNA sequences of Nyctotheroides parvus and Ncytoth‐eroides deslierresae that Affa'a and Hickey (unpublished) had submitted to GenBank to demonstrate that they formed a clade of clevelandellid symbionts from anurans. We provide here the details of our isolation and amplification of the SSrRNA genes from these two species of Nyctotheroides and resolve the assignment of taxa to this genus and the genus Nyctotherus .…”

We have used small subunit rRNA gene sequences to determine the phylogenetic relationships of species in three genera of endosymbiotic ciliates. We have confirmed that the astome Anoplophrya marylandensis is related to ciliates in the Class Oligohymenophorea, supporting the view that astomes are derived from hymenostome-like ancestors. We confirmed that Plaglotoma lumbrici, formerly considered to be a heterotrich, is a stichotrich spirotrich ciliate most closely related to Paraurostyla weissei in this analysis. Thus, the somatic polykinetids of Plagiotoma can be concluded to be cirri. We report the details of our isolation of Nyctotheroides deslierresae and Nyctotheroides parvus and confirm previous reports that these clevelandellids are related to the metopid and caenomorphid ciliates, now placed in the Class Armophorea.
