FIGURE 5. Placement of the two new species Farrea bowerbanki and Tretodictyum reiswigi in a phylogenetic tree (here NJ topology presented, see text) inferred from 18 S rDNA sequences of Sceptrulophora (Hexactinellida) currently available in DNA databases at this partition. Bootstrap support (> 80 %) is presented as percentages for 1000 replicates (NJ / ML). The tree is rooted with Iphiteon panicea. Scale bar: genetic distance.
