3.8 mm; a= 76; b = 9.0; c = 120; V = 47

Body arcuate, especially posteriorly.  Lateral fields 1/5 body width with obscure cells and pores.  Cuticle with distinct outer layer, doubly thick just posterior to lip region.  Lip region set off by slight depression.  Amphid apertures high on lips, seen as an obscure line.  Spear 100u long (94-105), first a slender tube, then abruptly expanded to a basal enlargement 75-90u long.  Esophageal gland nuclei as illustrated, the submedian usually obscure.  Cardia conoid without disc.  Intestinal cells with few colorless granules and very narrow lumen.  Vulva a deep, transverse slit with muscular labia.   Spermatheca 2 to 3 times as long as body width.  Z organ usually visible. Ovaries reflexed about halfway to vulva.  Slender bodies, unidentified, 8-10u long usually present in uteri.  Prerectum about 10 times as long as body width.  Males numerous with 5 or 6 low, mammiform supplements, sometimes closer together than those illustratedSpicula arcuate, massive with tiny lateral guiding pieces.  Tails of both sexes ending in a small cuticular process or peg.

Xiphinema vuittenezi is immediately recognized by its large size, terminal peg, symmetrical ovaries and median located vulva.
