Lainsonia legeri n. sp., Lankesterellidae, a parasite of Tupinambis nigropunctatus Spix, 1825, from Belem (Para, Brazil), was transmitted in the laboratory both by intraperitoneal and intra-oesophageal inoculation of blood from infected Lizards to clean young Tupinambis. The parasitaemia became patent between the 36th and 48th day ; schizogony and sporogony occur in the reticulo-endothelial system of the host. Rapid dissemination of infective forms to alI the tissues of the vertebrate host is ensured by a special mechanism: oocysts mar become detached from the walls of the vessels at their sites of development (lungs, kidney and brain) and migrate throughout the circulation to the other tissues. This is probably an adaptative mechanism to facilitate the transmission by predation from Vertebrate to Vertebrate. The authors propose to include the three genera Lainsonia, Lankesterella and Schellackia in a single family, the Lankesterellidae, which has the priority to the Schellackiidae.
