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. Isospora brygooi n. sp. from Furcifer pardalis has spherical to subspherical oöcysts with a slightly pitted wall, 20.7 (17-24.5) x 19.3 (16-23) microm and broadly ellipsoidal sporocysts, 12.2 (11.5-13) x 8.1 (8-8.5) microm, with Stieda and substieda bodies. Oöcysts of Eimeria glawi n. sp. from Furcifer pardalis are cylindrical to ellipsoidal, 27.7 (26-29.5) x 18.4 (17-19) microm, with ellipsoidal sporocysts, 7.3 (6.5-8) x 5.2 (5-5.5) microm. E. vencesi n. sp. described from F. pardalis has spherical to subspherical oöcysts, 14.3 (13-15.5) x 13.0 (12-13) microm, with small granules, one to three globular polar granules and ellipsoidal sporocysts, 7.3 (6.5-8) x 5.2 (5-5.5) microm. E. worthi n. sp., described from Furcifer oustaleti has spherical oöcysts, 17.9 (17.5-19.0) x 15.0 (14.5-16.0) microm without a polar granule and ellipsoidal to cylindroidal sporocysts, 8.2 (7.0-9.5) x 5.8 (5.0-6.5) microm. Oöcysts of E. brookesiae n. sp. from Brookesia decaryi are cylindrical, 25.6 (23-27) x 15.0 (13-16) microm with ellipsoidal sporocysts, 10.1 (9-11) x 6.9 (6-7) microm. Endogenous development of E. vencesi is confined to the intestine, while that of E. glawi occurs in the gall-bladder.
