A taxonomic reconsideration of some Plasmodium species from iguanid lizards

Saurian Plasmodium populations previously identified as P. tropiduri from Panama are described as subspecies or distinct species. The nominate subspecies, P. tropiduri tropiduri parasitizes Tropidurus species from Brazil, Guyana and Venezuela. Two other subspecies occur in Panama, P. tropiduri panamense from Anolis biporcatus and P. tropiduri aquaticum from the semi-aquatic lizards Anolis lionotus and A. poecilopus. Parasites found in Anolis frenatus are described as a distinct species, P. marginatum, while those from Anolis limifrons represent a third, un-named species. A parasite of Plica plica in Guyana, previously called P. cnemidophori, is designated P. guyannense, while identification of Plica umbra parasites as P. tropiduri is corrected to P. vacuolatum and Fallisia simplex.
