Globodera zelandican.sp. is described fromFuchsia excorticata(J. R. & G. Forst., Linn, f.) (Onagraceae), the New Zealand tree fuchsia. The new species can be distinguished from other species ofGloboderaby the average length of the stylet being, at 28 μm, more than 3 μm longer than the greatest length in the known species. A key to the species ofGloboderabased on the thickness of the cuticle and the ratio of fenestral length to analfenestral edge distance of the cyst, and on the stylet length and shape of the stylet knobs of infective juveniles is presented.
