Abstract A new species of isosporan parasite is described from the faecal contents of the buff-throated foliage-gleaner Automolus ochrolaemus and the olive-backed foliage-gleaner A. infuscatus collected in the rainforests of eastern Ecuador. Sporulated oöcysts are subspherical to ovoidal, 23.4×21.3 (18–28×17–24) μm, colourless, with a smooth, double-layered wall with the inner layer darker and thinner; the shape-index (length/width) is 1.1 (1–1.22). Oöcysts contain one polar granule, but lack a micropyle and an oöcyst residuum. Sporocysts are ovoidal, 15.4×9.9 (14–17×–11) μm, with a smooth single-layered wall and a small nipple-like Stieda body attached to a small, inconspicuous, acentric substieda body. Sporozoites are vermiform with one prominent posterior, refractile body (c. 4×5 μm), and a centrally located nucleus of equal size. Sporozoites are randomly arranged in the sporocysts with a subspherical sporocyst residuum composed of coarse granules.
