Description

The parasite was first described by Telford and Stein in 2000. Telford J.R. and Stein J. (2000) Two malaria parasites (Apicomplexa : Plasmodiidae) of the Australian skink "Egernia stokesii" J. Parasitol. 86 (2) 395-406 ]

Geographical occurrence

This species is found in Australia and infects the Australian skink "Egernia stokesii".

Clinical features and host pathology

The immature schizonts encircle the host cell nuclei and form an unbroken ring from apparent fusion of the attenuated ends.

Mature schizonts contract into halteridial or dumb bell-shaped forms 15.6 X 4.3 micrometres (length x width 66.2 µm^2) with 19-52 nuclei.

Rounded or oval gametocytes are 9.0 x 7.3 µm. Length x width is 66.9 µm^2 and length divdided by width is 1.24.

The gametocyte length x width is 2.63 times the host erythrocyte nucleus size and 1.79 the uninfected erythrocyte nucleus.
