Abstract: | Xiphinema waimungui n. sp. from native forest in the North Island, New Zealand, is distinguished from many Xiphinema spp. by having two equal female genital branches, Z differentiation absent and tail short, convex-conoid. Females are 2.71–3.19 mm long, odontostyle 117–130 µm and odontophore 65–75 µm. Four juvenile stages are distinguished; tail shape does not vary markedly. Males were not found. Longidorus waikouaitii n. sp. from a native forest remnant in the South Island, New Zealand, has a rather posteriorly positioned guide-ring, large female body size (>6 mm), a bluntly conoid lip region which is continuous with the body contour and a bluntly rounded tail less than an anal body width long. No males and few juveniles were found. A dichotomous key is provided to the seven species of longidorids currently known from New Zealand. |
