abstract = {Inferences of parabasalian phylogeny based on the small subunit (SSU) rRNA gene often hamper due to the high-level of sequence divergence. New protein sequences from five parabasalian symbionts of termites (devescovinid, calonymphid and three hypermastigids) were added to data sets of glycelaldehyde-3-phosphate dehydrogenase (GAPDH), enolase, a- and b-tubulins, and inferred phylogenetic relationships. GAPDH gave significant resolutions and showed overall congruence with the well-defined relationships found in the SSU rRNA-based phylogeny. The stability of the GAPDH tree increased after removing fast-evolving amino acid positions. Although several groups of taxa were commonly found, the other three proteins were poorly resolved particularly in branching orders of the groups. In the combined protein data and detailed GAPDH analyses, two hypermastigid lineages, Trichonymphida and Spirotrichonymphida branched from outside of trichomonads, and Trichonymphida most likely located at the basal position of parabasalids, both of which placements have been doubted in the SSU rRNA analyses. The GAPDH data overcame the problem of resolution and provided us a reliable framework of parabasalian phylogeny.}
