title: Studies on African saurian malarias: Plasmodium holaspi n. sp. from the flying lacertid Holaspis guentheri.
abstract: The African flying lizard Holaspis guentheri (Lacertidae) from the Uluguru Mountains, Tanzania was found infected by an undescribed malarial parasite, Plasmodium holaspi n. sp. Gametocytes were elongate, approximately twice the size of host cell nuclei, and showed prominent, irregular pigment granules. Schizonts were oblong or formed as rosettes, approximated the host cell nucleus in size, and produced 8-18 merozoites. Maturing gametocytes contained large masses or blocks of chromatin which can obscure sexual differentiation by staining reaction, while young gametocytes and asexual stages almost always occupy marginal positions in host cells. These characteristics distinguish P. holaspi from all other saurian Plasmodium species. This is the first malarial parasite described from African lacertid species.
