SUMMARY The phylum Nemata Cobb, 1919 is accepted as is the class Secernentea and subclass Diplogasteria. Within the subclass the two suborders Tylenchina and Aphelenchina are reunited in the order Tylenchida. The order is subdivided into four suborders : Tylenchina, Aphelenchina, Sphaerulariina and Hexatylina. This paper focuses on a revision of Tylenchina, here recognized as being composed of two superfamilies : Tylenchoidea and Criconematoidea. Seven families are recognizcd in Tylenchoidea : Tylenchidae, Anguinidae, Dolichodoridae, Bclonolaimidae, Pratylenchidae, Hoplolaimidae and Heteroderidae. Two families are recognized in Criconematoidea : Criconematidae and Tylenchulidae. Within these nine families, fifteen subfamilies are accepted in Tylenchoidea and four in Criconematoidea. A list of the families and their genera is included.
