Morphological examination was made of the larval forms of Grassenema procaviae (Cosmocercoidea: Atractidae), an autoinfective and viviparous nematode parasite in the stomach of Cape hyrax (Procavia capensis). Three different larval stages (second-, third- and fourth-stages), and the adult stage were found among the worms collected at necropsy of 3 hosts, which were reared in a zoo in Japan. Molting phases between the larval stages and the final molt to the adult stage were also observed.
