Description

The parasite was first described by de Mello and Diaz in 1936.

This parasite has only been described on one occasion. The description is incomplete and this species should be regarded as being of dubious validity until further work has confirmed or refuted these findings.

As described the schizonts were annular and amoeboid and between 1/5 and 1/6 of the erythrocyte in size. Black pigment was seen. 9-11 merozoites per schizont were seen. The gameotocytes were oval. No granules or dots were seen in the erythrocytes.
