Pyrsonympha is a genus of Excavata. It includes the species Pyrsonympha vertens. [1]

This report provides a detailed ultrastructural description of Pyrsonympha from the hind-gut of Reticulitermes flavipes. The motile axostyle is composed of 2,000-4,000 microtubules connected by cross-bridges.

Feb 1, 1975 · Protozoa of the genus Pyrsonympha are found attached to the cuticular lining of the hind-gut wall of the termite Reticulitermes tibialis by a specialized anterior structure referred to here as the ‘attachment organelle’.

Epi- and endobiotic bacteria associated with Pyrsonympha vertens, a symbiotic protozoon of the termite Reticulitermes flavipes. Trans. Amer. Micros. Soc., 93: 180-194. Two types of bacteria are found associated with Pyrsonympha vertens: (1) helically-shaped bacteria attached to the.

It has recently been demonstrated that a genus of oxymonads, Pyrsonympha, is phylogenetically related to the excavate taxon Trimastix. Here, we addressed issues of internal oxymonad evolution.

The termite gut flagellates are of interest because of their unusual motile organelles, their ability to digest cellulose, and their symbiotic relationship with prokaryotes inhabiting the insect gut. This report provides a detailed ultrastructural description of Pyrsonympha from the hind‐gut of Reticulitermes flavipes.

The rhythmic movement of the microtubular axostyle in the termite flagellate, Pyrsonympha vertens, was analyzed with polarization and electron microscopy. The protozoan axostyle is birefringent as a result of the semi-crystalline alignment of approximately 2,000 microtubules.
