  abstract = {{T}he guts of lower termites are inhabited by host-specific consortia of cellulose-digesting flagellate protists. {I}n this first investigation of the symbionts of the family {S}erritermitidae, we found that {G}lossotermes oculatus and {S}erritermes serrifer each harbor similar parabasalid morphotypes: large {P}seudotrichonympha-like cells, medium-sized {L}eptospironympha-like cells with spiraled bands of flagella, and small {H}examastix-like cells; oxymonadid flagellates were absent. {D}espite their morphological resemblance to {P}seudotrichonympha and {L}eptospironympha, a {SSU} r{RNA}-based phylogenetic analysis identified the two larger, trichonymphid flagellates as deep-branching sister groups of {T}eranymphidae, with {L}eptospironympha sp. (the only spirotrichosomid with sequence data) in a moderately supported basal position. {O}nly the {H}examastix-like flagellates are closely related to trichomonadid flagellates from {R}hinotermitidae. {T}he presence of two deep-branching lineages of trichonymphid flagellates in {S}erritermitidae and the absence of all taxa characteristic of the ancestral rhinotermitids underscores that the flagellate assemblages in the hindguts of lower termites were shaped not only by a progressive loss of flagellates during vertical inheritance but also by occasional transfaunation events, where flagellates were transferred horizontally between members of different termite families. {I}n addition to the molecular phylogenetic analyses, we present a detailed morphological characterization of the new spirotrichosomid genus {H}eliconympha using light and electron microscopy.},
