Pentatrichomonoides is a trichomonad flagellate (18-45 µm) with five anteriorly directed free flagella and a recurrent flagellum forming an undulating membrane. Anterior flagella arising from a gullet. Cell shape changeable, cigar-shaped, and truncated posteriorly or broadly triangular. Costa and undulating membrane often recurved posteriorly. No central axostyle, parabasal of variable shape. One species known at the time of writing - Pentatrichomonoides scroa from Mastotermes darwiniensis and Glyptotermes dudleyi, long form (Giemsa).
