Hemolivia pulcherrima n. sp. in erythrocytes of the freshwater turtle Rhinoclemmys pulcherrima manni; all figures are in the same scale. Slim elongated stage resembling trophozoite (A). Merozoites in transition developing to meronts can be vacuolated (B, C). A single stage determined as possible meront contained large vacuoles, but no visible nuclei (D). Developing gamont in pre-final stage has a hardly visible or invisible nucleus (E). Mature gamont can have parallel arms in its parasitophorous vacuole (F), or crossed, visible as thin blue lines forming “X structure” (black arrowhead, G). Multiple infections of a single erythrocyte can be seen (H).
