In the past years, several writers described eudotokia matricida in nematodes belonging to the family Rbabditidae. In 1958, LOOF dealt with two cases he observed in Apbeltncboides fragariae and Pratylencbus coffeae , showing that such phenomenon eventually occurs in the Tylencbida, families Apbelencboididae and Tylencbidae respectively. A third case referring to another tylenchid nematode is described in this paper, the species envolved having been identified as Meloidogyne javanica, of the family Heteroderidae.
