Perhaps the most characteristic feature of this genus is the formation of pedunculated oocyts in the mosquito midgut.

This species is found in a number of countries including Brasil, India, Indonesia, Japan, Philippines, Malaysia, Mexico, South Africa, Sri Lanka, Taiwan, Tanzania and Uruguay.

It is thought that this species probably originated in South East Asia but this requires confirmation.

Clinical findings associated with high parasitemia are anemia, diarrhea and weight loss that may lead to death.

Increases in the thrombocyte number and total leukocyte and basophil count have been reported.

Laboratory findings included parasitemia, splenomegaly, pulmonary oedema and schizonts in the reticuloendothelial system.

[3] This species infects the Chinese bamboo partridge, white eared-pheasant, Malayan jungle fowl (Gallus gallus spadiceus), Sri Lankan junglefowl, grey-winged francolin, crested francolin, wild turkey and the Indian peafowl.
