(Lecudinidae, Eugregarinida), a new gregarine parasitizing the larger grain borer, Prostephanus truncatus Horn (1878) (Bostrichidae, Coleoptera).
The gregarine parasite, Locklin said, is single cell and shows up in the intestinal tract of the dragonfly.
Although the parasite is closely related to cryptospiridium parasite that causes digestive symptoms in humans, Locklin said the gregarine parasite is not harmful to people.
