Check-list of the valid genera of Dilepididae (Cestoda, Cyclophyllidaea), their synonyms and hosts.

The revised family Dilepididae contains 102 valid genera, 11 new genera included (Bona 1994 a,b, in press). The synonyms, old and new ones, and the sub-genera raised to generic rank are 41. The revision of the family was undertaken as a contribution to the "IIP Keys to the Cestode Parasites of Vertebrate" and with the intention to provide new elements for future suprageneric systematics of the group.

A new genus of Metadilepididae (Cestoda: Cyclophyllidea) parasitic in Terpsiphone rufiventer (Aves: Muscicapidae) from the Ivory Coast.

Pseudadelphoscolex eburnensis, a new genus and species of metadilepidid Cyclophyllidea parasitic in the red-bellied paradise flycatcher, Terpsiphone rufiventer, from the Ivory Coast, is described. The new species is characterized by davaineidlike rostellar hooks, absence of a rostellar pouch, a huge cirrus pouch in gravid proglottids, a bilobed uterus that becomes progressively reticular, absence of a paruterine organ, and eggs with an internal coat forming a crescentic protuberance outside the embryophore. The presence of a single row of rostellar hooks together with the lack of spines on the sucker and the structure and position of the uterus exclude this new material from Davaineidae. It cannot be placed in Dilepididae due to the lack of a rostellar pouch or in Paruterinidae because of the lack of a paruterine organ. The position of the excretory ducts in relation to the genital pores and the alternance of these pores are the main characters used to exclude this new species from the known genera of Metadilepididae. The diversity of forms of Metadilepididae in intertropical terrestrial birds is increased, and the validity of this taxon is strengthened.

The genus Clelandia Johnston, 1909 and its affinities with Parvitaenia and Neogryporhynchus (Cestoda, Dilepididae).

The diagnosis of Clelandia has been amended. The validity of the genus and its closeness to Parvitaenia and Neogryporhynchus are discussed. On the basis of its morphology and of the specificity of the dilepidid cestodes within the order Ciconiiformes, one many admit that its host belongs to the suborder Ardeae, and that the original doubtful diagnosis of the host was wrong. Clelandia seems to confirm that the genus Parvitaenia is a nucleus of evolutionary radiation among cestodes of the Ciconiiformes, with peculiar traits in the Australian region, and that it isn't a homogeneous unit.
