Metacoronympha (met-a-caw-row-nymph-a) one of the multinucleated trichomonad flagellates, always with many flagella. Flagella in small groups of 4, three extending outwards and one recurrent. The flagella are linked to nuclei which are arranged in a spiral around the anterior end of the cell as is evident from this image. Probably M. senta, from the termite Incisitermes. Phase contrast. This picture was taken by Linda Amaral Zettler, Lorraine Olendzenski, and David Patterson of material from the intestines of the termite, Incisitermes. Image copyright: L Amaral-Zettler, L. Olendzenski and D. J. Patterson, image used under license to MBL (micro*scope).

|Description of Metacoronympha: Multinucleate flagellates (22-92 µm) composed of 66-345 karyomastigonts arranged along spiral lines from the apex. Each karyomastigont comprises three anterior flagella and a recurrent thick flagellum adhering along a cresta in its proximal part. Axostyles independent, grouped at the posterior end. Parabasal bodies dot-shaped applied against the nuclei. The only species, M. senta, occurs in several termites of the genus Incisitermes (formerly Kalotermes) in America.
