The species is only known from a mosquito fossil, dating from the Cenozoic era, that was found embedded in amber.

The mosquito vector was identified as Culex malariager.

[1][2] The vertebrate host of this species is unknown but it seems likely that it may have been a bird.

[1] It appears that it may have been a relation of Plasmodium juxtanucleare which would place it in the subgenus Bennettinia.

The host seems likely to have been a member of the order Galliformes but this cannot be confirmed.
