Five new species of coccidia (Apicomplexa : Eimeriidae) from Madagascan chameleons (Sauria : Chamaeleonidae)

Coprological examination of 19 Madagascan chameleons of the genera Furcifer and Brookesia revealed the presence of five new coccidian species. Isospor a brygooi n. sp. from Furcifer pardalis has spherical to subspherical oocys ts with a slightly pitted wall, 20.7 (17-24.5) x 19.3 (16-23) mum and broad ly ellipsoidal sporocysts, 12.2 (11.5-13) x 8.1 (8-8.5) mum, with Stieda an d substieda bodies. Oocysts of Eimeria glawi n. sp. from Furcifer pardalis are cylindrical to ellipsoidal, 27.7 (26-29.5) x 18.4 (17-19) mum, with ell ipsoidal sporocysts, 7.3 (6.5-8) x 5.2 (5-5.5) mum. E. vencesi n. sp. descr ibed from F. pardalis has spherical to subspherical oocysts, 14.3 (13-15.5) x 13.0 (12-13) mum, with small granules, one to three globular polar granu les and ellipsoidal sporocysts, 7.3 (6.5-8) x 5.2 (5-5.5) mum. E. worthi n. sp., described from Furcifer oustaleti has spherical oocysts, 17.9 (17.5-1 9.0) x 15.0 (14.5-16.0) mum without a polar granule and ellipsoidal to cyli ndroidal sporocysts, 8.2 (7.0-9.5) x 5.8 (5.0-6.5) mum. Oocysts of E. brook esiae n. sp. from Brookesia decaryi are cylindrical, 25.6 (23-27) x 15.0 (1 3-16) mum with ellipsoidal sporocysts, 10.1 (9-11) x 6.9 (6-7) mum. Endogen ous development of E. vencesi is confined to the intestine, while that of E . glawi occurs in the gall-bladder.
