This paper reports on Xiphinema-species previously identified as Xiphinema zulu Heyns, 1965 and X. mampara Heyns, 1979. An intensive study of all available material revealed the presence of three closely related species viz. X. zulu, X. mampara and X. ornatizulu n.sp. A fourth species in this complex was recently described as X. ornativulvatum Kruger & Heyns, 1987 and is also compared with the above mentioned species. X. zulu, X. ornatizulu and X. ornativulvatum have uterine spines and a pseudo-Z-organ, while only the latter two have cuticular ornamentation around the vulva. In X. mampara, which is the commonest and most widely distributed of the four species, there are amphimictic as well as parthenogenetic populations. Two size forms can be distinguished among the parthenogenetic populations, one of which is quite similar to the amphimictic form, while the other is much smaller. Distribution records arc given for all species.
