This subgenus was shown on the basis of DNA analysis to be polyphyletic. A revision of this subgenus on a morphological basis by Landua et al. moved several of the species in this subgenus into a new subgenus Papernaia.[2]

Description

Species in the subgenus Giovanolaia have the following characteristics:

Schizonts contain plentiful cytoplasm, are larger than the host cell nucleus and frequently displace it. They are found only in mature erythrocytes.

Gametocytes are elongated.

Both gametocytes and schizonts are stretched along the red cell nucleus.

Exoerythrocytic schizogony occurs in the mononuclear phagocyte system.
