These species illustrate the close relationships between their host generaAepypo­ dius and Talegalla, and suggest that Alectura is more distantly related. An overview is given of the hospitalic distribu­ tion of all genera of chewing lice so far known off the Megapodiidae, with special reference toAepypodius arfakianus and A. bruijnii. Key words Aepypodius bruijnii, Amblycera, Ischnocera, new species & subspecies, parasitophyletic studies, Waigeo. Zusammenfassung Nach dem Autor vorliegendem noch sehr lückenhaften und zumeist von alten Museumsbälgen stammenden Material werden die folgenden auf dem BraunbrusttalegallaAepypodius bruijnii (O ustalet, 1880) nachgewiesenen Federlinge beschrieben: die Amblyceren Kelerimenopon aepypodi Price & Emerson , 1966 sensu lato und Talegalligogus wil­ helmi waigeuensis n. ssp. und die Ischnoceren Megathellipeurus mumesensis n. sp., „Oxylipeurus“ aepypodius Clay, 1938, Talegallipeurus tenuis Mey, 1983, Weehalia hakalphilus n. sp. und Homocerus sp. Diese Arten weisen auf enge verwandtschaftliche Beziehungen ihrer Wirtsgattungen Aepypodius und Talegalla, denen Alcetura ferner steht. Unter besonderer Berücksichtigung von Aepypodius arfakianus und A. bruijnii wird die hospitale Verbreitung aller bisher auf Großfußhühnern (Megapodiidae) festgestellten amblyzeren und ischnozeren Federlingsgattungen zur Übersicht gebracht.
