2 NEW SPECIES OF OSWALDOCRUZIA (NEMATODA, TRICHOSTRONGYLINA, MOLINEOIDEA) PARASITIZING AMPHIBIANS FROM CAMEROON

Like all the other Ethiopian Oswaldocruzia already known, the 2 new sp ecies are characterized by uncomplicated spicules, without clear diffe rentiation between the handle and the lamina, the latter being distall y divided into 4 or 5 tips. Oswaldocruzia ohlerae n. sp., a parasite o f Bufo camerounensis, is characterized (1) by a caudal bursa of type I I like O. polycercus Baker, 1982, a parasite of B. polycercus but O. p olycercus has no cervical alae; (2) by cervical alae composed of 2 tri angular crests like O. johnstoni, a parasite of Petropedetes johnstoni Durette-Desset and Vaucher, 1979 but O. johnstoni has a caudal bursa of type I. Oswaldocruzia ineichi n. sp. known only through a sole male has cervical alae composed of 2 triangular crests like O. ohlerae n. sp but it differs by a caudal bursa of type I and by cuticular crests well developed at midbody. The closely related species is O. johnstoni which has a caudal bursa of type I and cervical alae conposed of 2 tr iangular crests. But in O. ineichi, rays 8 arise on the dorsal ray and not at its base; in the oesophagal region, the dorsal crests spread o n the whole dorsal side and the shape of the spicular tips is differen t.
