Die Goniodiden (Insecta, Phthiraptera, Ischnocera) der Großfußhühner (Megapodiida

The goniodid chewing lice (Goniodidae) of the suborder Ischnocera inhabiting the megapodes (Megapodiidae) constitute a heterogeneous species ensemble. A total of 18 taxa has been described so far which, on the basis of morphological characteristics, can be assigned to 9 defined and illustrated genera. Apart from Goniocotes BURMEISTER (1 sp. on Macrocephalon maleo), the members of all these genera are found only on megapodes. These are (number of species in brackets): Leipoiella MEY (I), Megatheliella MEY (l), Maleophilus nov. gen. (at least l), Maleoicus nov. gen. ( 2 spp., 4 sspp.), Euligoniodes nov. gen. (1), Homocerus KÉLER (6), Weelahia nov. gen. (2), and Lobicrotaphus nov. gen. (1). Their host-dependent distribution is described. Remarks on the genera and species draw attention to gaps in the present knowledge as well as probable intergeneric relationships, and contain parasitophyletic deductions. It is shown that Aurinirmus TENDEIRO, 1983 is a objectiv synonym of Homocerus KÉLER, 1939. The type host of Maleoicus m. minor (PIAGET) is not Megapodius r. reinwardt DUMONT but probably M. decollatus OUSTALET. The species-dependent distributions of Maleoicus minor sensu lato, and of M. biordinatus sensu lato show that a western and an eastern group of the host genus Megapodius can be distinguished. The females of Euligoniodes ocrea (PIAGET) is described for the first time, and its type host affiliation to Eulipoa wallacei, in doubt until now, is confirmed. The males of Goniocotes pallidiflavus PIAGET is illustrated for the first time. In the appended host-parasite list, all Phthiraptera (Amblycera and Ischnocera) currently known to inhabit megapodes are set out. Some 'new' records of specimens from old museum skins (in the collection of the Natural History Museum, Rudolstadt), not taxonomically dealt with before, have been integrated into this list. The list makes clear that there are considerable gaps in the recording of all chewing lice groups inhabiting the megapodes, and that the discovery of new taxa must be expected.
