- Abstract
Abstract: Spirotrichonymphea is a class of hypermastigote parabasalids defined by their spiral rows of many flagella. They are obligate hindgut symbionts of lower termites. Despite more than 100 yr of morphological and ultrastructural study, the group remains poorly characterised by molecular data and the phylogenetic positions and taxonomic validity of most genera remain in question. The genus <italic>Spirotrichonympha</italic> has been reported to inhabit several termite genera, including <italic>Reticulitermes</italic>,<italic> Coptotermes</italic>, and <italic>Hodotermopsis</italic>. The type species for this genus, <italic>Spirotrichonympha flagellata</italic>, was described from <italic>Reticulitermes lucifugus</italic> but no molecular data are yet available for this species. In this study, three new <italic>Spirotrichonympha</italic> species are described from three species of <italic>Reticulitermes</italic>. Their molecular phylogenetic position indicates that the genus is not monophyletic, as <italic>Spirotrichonympha</italic> species from <italic>Coptotermes</italic>,<italic> Paraneotermes</italic>, and <italic>Hodotermopsis</italic> branch separately. In contrast, the genus <italic>Holomastigotoides</italic> is monophyletic, as demonstrated using new sequences from <italic>Holomastigotoides</italic> species. The presence of <italic>Holomastigotoides</italic> in <italic>Prorhinotermes</italic> and the distinct phylogenetic positions of <italic>Spirotrichonympha</italic> from <italic>Reticulitermes</italic> and <italic>Coptotermes</italic> are consistent with a previously proposed symbiont fauna replacement in the ancestor of <italic>Reticulitermes</italic>.
