1. The structure of the head in four samples of the genus Allodapa from Madagascar birds is described and shown to represent stages in the functional deformation of the pharyngeal portions.
2. All the specimens are considered to belong to Allodapa suctoria (Molin, 1860) s.l. and are described. Their hosts are: Margaroperdix sp. Centropus toulou, Coua caerulea and C. raynandii.
3. The species of the family Subuluridae known from Madagascar hosts are discussed and it is shown that they represent a minor parasite fauna which has most probably been secondarily introduced.
4. It is reported that Subulura prosimiae Baer, 1935 is indistinguishable from Primasubulura distans (Rudolphi, 1819) and that the record of the former species given by Chabaud and Petter (1958), based only on females, is that of a Subulura species and not a Primasubulura.
5. A Subulura species is reported from Coua gigas.
