Novyella
Novyella is a subgenus of the genus Plasmodium - all of which are parasitic protozoa. The subgenus was created in 1963 by Corradetti et al.. Species in this subgenus infect birds. It unites the avian malaria parasites with small erythrocytic meronts and elongated gametocytes.
The type species is Plasmodium vaughani.
This subgenus was created on the basis of morphology. Subsequent DNA studies showed it to be polyphetic. It has been revised by Landau et al and currently contains only those species with a white/blue globule in the cytoplasm. Several of the species that were included in this subgenus have now been moved to a new subgenus Papernaia.
