Abstract
World literature on Plasmodium of squamate reptiles (1909-1975) includes 156 published accounts on 54 valid species and subspecies: Africa-30 reports on 9 spp.; Australia, Asia and Oceania-12 reports on 6 spp. and 2 sspp; Americas-116 reports on 37 spp. More than half of these reports and new species descriptions appeared during the last 10 yr. Most concern plasmodia in lizards of the Neotropics, Georgia (P. floridense, a Neotropical-Caribbean parasite) and California (P. mexicanum). African host species are all lizards: 4 agamids, 3 skinks, 2 chamaeleonids, 1 chordyline and 1 gerrhosaurine. Australasian host species are also all lizards: 6 agamids, 9 skinks, 2 lacertids, 1 (or 2?) gekkonids and 1 varanid. American host species include 12 snakes and 87 lizards: 34 anolines, 12 sceloporines (plus 11 others experimentally infected), 4 basiliscines, 5 tropidurines, 2 iguanines, 2 skinks (one questionable), 2 anguids (a total of 4 animals), 4 sphaerodactylines, 2 gekkonines and 11 teiid species.
