Studies on two new coccidia from the Venezuelan lizardCnemidophorus lemniscatus lemniscatus: Hoarella garnhamigen.nov., sp.nov. andEimeria flaviviridis americanasubsp.nov.

Abstract

This work contains the description of two new Coccidia parasitic in the South American lizard Cnemidophorus lemniscatus lemniscatus. One is identified as Eimeria flaviviridis americana subsp.nov., which is described and discussed in relation to the other species recorded from sauria. The other is Hoarella garnhami gen.nov., sp.nov., whose position in the family Eimeriidae necessitated a revision of the classification of the Coccidia Eimeriidae.I wish to acknowledge the help and encouragement I received from Professor P. C. C. Garnham, in whose department this work was carried out. My thanks are also due to Dr Cecil Hoare for his private communications and assistance in the interpretation of histological specimens. The author is grateful for co-operation of the School's Photograph Staff and to members of the staff of the Department of Parasitology, especially to Mr P. E. Nesbitt for his valuable sections. Finally, the author is indebted to the Consejo de Desarrollo Cientifico y Humanístico de la Universidad Central, Caracas, for their assistance in the form of a scholarship during the tenure of which this work was produced.

New coccidia from Australian lizards. II. Eimeria

“…This parasite caused the cell to become pedunculate and sporulation was seen to have begun in oocysts still enclosed within the host cell. Hypertrophy of the gall bladder epithelium was also described by Arcay de Peraza (1963) with E. flaviviridis americana from Cnemidophorus I. lemniscatus. Brygoo (1963) also described and figured pedunculate cells from the gall bladder of Chamaeleo brevicornis with an eimerian species which had mature oocysts and free sporozoites in the bile.…”

Eimeria urosauris n. sp., a Coccidium from the Lizard Urosaurus graciosus Hollowell, in California

“…This Eimeria is distinct from those of lizards previously listed (2,5), and is also distinct from and in a different host than 1 described since those listings ( 6 ) . This new Eimeria is herein described and depicted as Eimeria urosauris n. sp.…”
