Key to the freshwater bothriocephalideans from Africa In order to facilitate identification of bothriocephalidean cestodes found in the freshwater fish in Africa, a simple key based on gross morphology is provided. 1 Apical part of scolex unarmed (without hooks).............................................................. 2 - Apical part of scolex armed (with hooks)................................................................... 3 2 Scolex heart-shaped, with deep, narrow bothria; external segmentation present............. Bothriocephalus acheilognathi - Scolex elongate to lanceolate, with shallow and wide bothria; external segmentation absent....... Ichthybothrium ichthybori 3 Scolex large (> 700 μm); vitelline follicles cortical, numerous; testes numerous (> 30, usually more than 100); eggs with hard shell (capsule)........................................................................................ 4 - Scolex small ( 40 hooks shorter than 90 μm; cirrus-sac large (ratio of cirrus-sac width to width of segment 16–39%)............................................. Kirstenella gordoni 5 Small worms ( than 36 hooks on apical disc, hooks large, up to 100 μm long.................................................................... Tetracampos martinae
