Garnia is a genus of parasitic protozoa belonging to the phylum Apicomplexia.


The genus was created in 1971 by Lainson et al.[1]


Ulike members of the Plasmodiidae and Haemoproteidae, species in this genus do not produce pigment when developing in the erythrocytes.

Species in this genus are distinguished from members of the Leucocytozoidae by their schizogony in the red and white cells of the peripheral blood.

The vectors of this genus are not known but it is suspected that phlebotomine sandflies may act in this regard.[2]

The type species is Garnia gonatodi.


Species in this genus infect lizards.

Geographic distribution[edit]

This genus has been described in South America.
