Photo Gallery- Konza Prairie

L = 0.9 mm; V = 81
Body slightly arcuate when relaxed by gentle heat. Lip region about 1/2 as high as wide. Spear about 12u long with small but distinct knobs. Male slightly shorter than female with more cylindroid body. Bursa rising about opposite proximal ends of spicula and extending about 1/3 tail length. Tails of both sexes ending in a fine pointed, rarely slightly rounded, terminus. Ditylenchus valveus is distinctive because of its unusually long tails, 6 lines in lateral field and conspicuous valvular apparatus of entrance to uterus.
