This new heterotrophic flagellate has two flagella inserted in the subapical region and a conspicuous ventral groove where bacteria are phagocytosed. Several microtubular fibres are connected to the two basal bodies: a dorsal root that plays the role of a MTOC for cortical microtubules, a left and a right ventral root that border the ventral groove, a root on the left side inserted between the Golgi body and the nucleus, and two fibrils that outline the bottom of the groove. Several features suggest a phylogenetic relationship with collodictyonids, i. e. a similar constriction at the base of the flagella, a similar desmose between the basal bodies that includes the origin of the left root, a similar arrangement of flagellar roots, and tubular mitochondrial cristae. Several features are more specific, such as a fibrillar rhizostyle adhering to a mitochondrial lobe and the single, small dictyosome.
