2 NEW COCCIDIA (PROTOZOA - EIMERIIDAE) FROM COSTA RICAN LIZARDS WITH A REVIEW OF EIMERIA FROM LIZARDS

SYNOPSIS. Thirty‐three lizards from Costa Rica were examined for coccidia. Cryptosporidium ctenosauris sp. n. is described from Ctenosaura similis, Eimeria basilisci sp. n. from Basiliscus basiliscus, and additional data are added to the description of Isosporacnemidophori Carini, 1942. Ellipsoidal oocysts of C. ctenosauris averaged 21.7 by 11.5 μ. They had no polar body or micropyle but had an oocyst residuum; the oocysts contained 4 elongate sporozoites with averaged 15.0 by 3.4 μ. The oocysts of E. basilisci were ellipsoidal and averaged 38.0 by 17.8 μ. They had no oocyst residuum or polar body. Their sporocysts were ovoid to ellipsoidal and averaged 12.7 by 7.0 μ. A sporocyst residuum was present. Copyright © 1969, Wiley Blackwell. All rights reserved
