This species was described by Buck, Coudurier and Quesnel in 1952. Its description was amended by Garnham and Uilenbe.
It was discovered in a splenectomised Lemur fulvus rufus in 1951 and it is named after Dr. H. Foley of the Pasteur Institute of Algeria.
The infected erythrocyte becomes enlarged.
This species is found in Madagascar.
The only known host is the lemur Lemur fulvus rufus.
