Fig. 1 a.

Cell is spherical with single, short, thick, rod-like tentacle by which this parasite of the peritrichs attaches to the host body. Lorica absent. Macronucleus spherical, centrally located. There are two contractile vacuoles, placed near the opposite site of the tentacular region of body. Reproduction by semi-circumvaginative budding.

Dimensions: cell body diameter 30–35; length of tentacles 15–20; diameter of macronucleus 8–12. Previous measurements: cell body diameter 30–35.

Material examined. Found as ectoparasite of epibiont peritrich species from Lethocerus sp. Mexico. Near Grutas de la Estrella, Ixtapan de la Sal. State of Mexico. 1550 m.a.s.l. (18° 43’ 30.7” N; 99° 35’ 59.1 W). 18.09.2005.
