| critical taxonomic revision of parabasalids with description of one new genus and three new species. | we propose a new classification of parabasalia which is congruent with both ultrastructural and molecular-phylogenetic studies. we identify six main parabasalid lineages and give them the rank of class: hypotrichomonadea, trichomonadea, tritrichomonadea, cristamonadea, trichonymphea, and spirotrichonymphea. trichomonadea is characterized by a single mastigont and by the absence of both a comb-like structure and an infrakinetosomal body. most representatives also possess a lamelliform undulating ... | 2010 | 20093080 |
