The monophyly of the lineage that includes the Notonectidae and the Pleidae + Helotrephidae is supported by one synapomorphy (32-4).
MicroRNAs support the monophyly of enteropneust hemichordates.
Considering the reciprocal monophyly of regional samples at mitochondrial gene regions and extensive lineage sorting at nuclear gene regions, the results appear to be robust to sample size (Rosenberg 2007).
Damgaard (2008b) included representatives of PIatyvelia, Steinovelia, Stridulivela, and Velia, but found poor branch support and no convincing diagnostic characters for Veliinae, and suggested that the monophyly of the subfamily should be tested by inclusion of more taxa.
A study such as this with only three representatives of the many species in outgroup taxa is not designed to test thelodont monophyly. A more rigorous test of monophyly would involve a much larger sampling from among other jawless vertebrates, and a much larger number of characters.

Evidences were presented by the latter mentioned author for that the Mesosemiina cluster (sensu stricto) has characters that support the monophyly of the subtribal taxon (HALL, 2003).
Monophyly is an assumption built into the methods of DNA sequence analysis, but it has its limitations.
