[A filaria of African Muridae in the wall of the colon: Monanema martini n. sp].

Description of M. martini n. sp. (= M. nilotica El Bihari et al., 1977 sensu Bain et coll., 1985), a parasite of Arvicanthis niloticus from Mali. The natural host is Arvicanthis niloticus from Mali; the description is based on material from experimentally infected laboratory-bred rodents (holotype from A. niloticus; other specimens from Lemniscomys striatus). Like other related species the microfilariae of M. martini are said to be "skin dwelling" (in fact they are in cutaneous lymphatic vessels). The main characteristic feature of this new species is the localization of the adults in the lymphatic vessels of the colon.
