HETERODERA-LITORALIS SP-N (NEMATODA, HETERODERIDAE) FROM AUSTRAL GLASSWORT, SARCOCORNIA-QUINQUEFLORA, IN NEW-ZEALAND

Heterodera litoralis sp.n, (Nematoda: Heteroderidae) is described from austral glasswort, Sarcocornia quinqueflora (Ung.-Sternb.) A.J. Scott (Chenopodicaeae), a coastal succulent common in Australia, New Caledo nia and New Zealand. The new species resembles Heterodera turcomanica in the orientation of the subterminal fenestrae on the vulval cone. H. turcomanica is a species in the H. avenae group. The long vulval slit of about 40 mu m excludes the new species from the H. avenae group. A mong the Heterodera species with a long vulval slit H, litoralis most closely resembles H. humuli (cysts bifenestrate. vulval bridge wide, v ulval slit long, underbridge present, bullae lacking). H. litoralis di ffers from H, humuli by the longer, more slender cysts and the longer stylet of the second-stage juveniles.
