Two new species of Longidoridae (Nematoda) from New Zealand forests

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.[PUBLICATION ABSTRACT]
