La famille des Dolichodoridae est redéfinie; elle est limitée aux deux genres Dolichodorus et Neodolichodorus. Brachydorus est considéré comme un genus inquirendum. La position des Dolichodoridae à l’intérieur des Tylenchoidea est discutée. Chitwood (1950) created the subfamily Dolichodori-nae under Criconematidae. As described by Chitwood, this family is a motley assembly of genera sharing a single character: a long spear (Chitwood wrote: “Stylet shaft greatly elongated ”; actually in al1 the concerned genera, it is the cone which is elongated). Chitwood placed Criconema, Criconemoides and Henticycliophora in the subfamily Criconematinae; Paratylenchus and Cacopaurus in Paratylenchinae, and Dolichodorus and Belonolaimus in ’ Dolichodorinae. This latter subfamily was said to differ from the other two ones by a cuticle coarsely striated with three or more lateral lines, and by females with two genital branches. The caudal alae ar
