A new genus of Dilepididae (Cestoda) of the yellowbill Ceuthmochares aereus (Cuculidae) from the Ivory Coast.
Bonaia africana n. gen., n. sp. (Cestoda: Dilepididae) has been found in Ceuthmochares aereus (Aves: Cuculidae) in the Ivory Coast (West Africa). This new tapeworm is mainly characterized by its unusual rostellar hooks that are implanted irregularly and which present a variable form and length in the same rostellum. The differential diagnosis, particularly in comparison with the closely related genera Liga and Amoebotaenia, is presented: Liga possesses an atrial bundle of setae and Amoebotaenia 1 row of well built hooks with a typical blade. It is assumed that the unusual disposition of the rostellar hooks described here could be a transitional form between the 1- and 2-row patterns or a degenerate derivative of a regular arrangement.
