. Four isosporan species are described from the small tree finch, Camarhynchus parvulus from Isabela Island on the Galapagos Archipelago. Isospora exigua n. sp. oocysts subspheroidal, one‐layered, smooth, yellow‐brown color, 20.4 × 20.1 (20‐23 × 18‐23) μm, with no micropyle, residuum, or polar body. Sporocysts ovoidal, 14 × 9.5 (13‐15 × 8‐10) μm, with small Stieda and substieda bodies and irregular‐shaped residuum. Isospora rotunda n. sp. oocysts subspheroidal, single‐layered, smooth, yellow‐brown wall with large polar body and no micropyle or residuum, 20.9 × 20.8 (20‐24 × 19‐23) μm. Sporocysts ovoidal, 15 × 9.7 (13‐16 × 9‐10) μm with knob‐like Stieda bodies, prominent substieda bodies and round residuum. Isospora fragmenta n. sp. oocysts subspheroidal with no micropyle or residuum but with many splinter‐like polar granules and a smooth, colorless, single‐layered wall, 25.3 × 24.2 (24‐27 × 23‐25) μm. Sporocysts piriform 15.4 × 11.5 (14‐17 × 11‐12) μm with knob‐like Stieda bodies, prominent substieda bodies, and irregular‐shaped residuum. Isospora temeraria n. sp. oocysts ellipsoidal with one polar body, no micropyle or residuum, and wall of a single layer, smooth, yellow‐brown color, 25.4 × 21.1 (21‐30 × 17‐23) μm. Sporocysts piriform, 15 × 10 (14‐15 × 9‐11) μm with knob‐like Stieda bodies, prominent substieda bodies, and a round residuum. One woodpecker finch, Cactospiza pallida , was found to be infected with I. exigua , and a warbler finch, Certhidea olivacea was infected with I. fragmenta .
