Spirotrichonympha (spire-o-trick-o-nympha-a) is a trichonymphid flagellate from the intestines of the termite Reticulotermes. These are hypermastigids in which the flagella insert in spiral arrays. Nucleus lies some distance behind the anterior end of the cell, but more or less determines the boundary between the front and the back of the cell. The back of the cell is capable of ingesting particles of wood. Phase contrast.

Holomastigotes are spirotrichonymphids with flagellar rows originating from the apex and progressing helically covering the whole cell body. In a species the size and the number of flagellar rows are variable. Nucleus very anterior, no columella. Dictyosomes scattered along the flagellar rows or concentrated at the posteriror of the nucleus. Axostyle present in some species. Cytoplasm filled with spherical food vacuoles, no wood particles, pinocytic nutrition. Holomastigotes elongatum Grassi, 1892, large form with five or six flagellar rows, flagella adherent to the cell body in their proximal part, anterior nucleus (two focal planes, interferential contrast). This species occurs in Reticulitermes lucifugus grassei, R. flavipes or its synonym R. santonensis, and Hodotermopsis sjoestedti.

-
Large (80-180 µm) spirotrichonymphids with an anterior pole generally spiralled and bare, from which originate the helical flagellar rows that generally do not reach the posterior end. No rostrum or columella. Spot-shaped dictyosomes situated between the flagellar rows. Compound axostylar trunk that does not protrude at the posterior end. Occuring in termites, many species in Heterotermes, Coptotermes, Schedorhinotermes such as Holomastigotoides hemigymnum from Coptotermes sjoestedti. Whole cell with spiralled flagellar rows, posterior part free of flagella, anterior nucleus (protargol staining).
