Description[]

The parasite was first described by Telford and Wellehan in 2005.[1]

Neither the schizonts nor the gametocytes have any effect upon dimensions of host erythrocytes or their nuclei.

The schizonts average 4.3 x 3.5 micrometres (range: 3.0 - 6.0 x 3.0 - 5.0) in size.

They produce on average 4.9 merozoites (range: 3.0 - 8.0) which are usually arranged as a fan.

The gametocytes average 5.9 x 5.5 micrometre (range: 5.0 - 6.6 x 5.0 - 6.0). The length x width product is 31.9 micrometre^2 (range: 25 - 40) and the length/width ratio is 1.06 (1.0 - 1.2).

The gametocytes are not sexually dimorphic in either size or shape.

Geographical occurrence[]

This species is found in New Guinea.

Clinical features and host pathology[]

This species infects the crocodile skink Tribolonotus gracilis.
