In case it helps, IRMNG has:
Xenopus Penzig & P.A. Saccardo, 1901 -- (fungus, accepted genus, = OTT "Xenopus in Nucletmycea")
Xenopus Roelofs, 1875 accepted as Ixalma Pascoe, 1871 -- (Coleoptera, synonym, = OTT "Xenopus in Protostomia")
Xenopus Wagler, 1827 -- (Amphibia, accepted genus, = OTT "Xenopus in Deuterostomia")
