Extract

Amongst cestodes collected from birds in the Lake Kariba district, Southern Rhodesia, was a dioecious species of the genus Gyrocoelia Fuhrmann, 1800, obtained from a darter, Anhinga rufa.

Ortlepp (1037) described, from a single poor specimen, a new species in this genus, which he termed G. kiewietti. Ortlepp thought that his specimen was functionally monoecious, the ovary and vitellaria appearing after the testes had disappeared. Although the present material is definitely functionally dioecious, it is thought that it is the same species as Ortlepp found as the number, size and arrangement of the rostellar hooks are very similar.
