Longidorus breviannulatus n. sp. was associated with stunted corn in Iowa. The nematode has wide bilobed amphidial pouches, a guiding ring 21-26 mum from the anterior end of the body, an odontostyle 81-88 mum long, and a spear extension 28-45 mum long. The most frequent collections and the greatest numbers of the nematode in the field occurred in sandy soils. Nematodes increased in greenhouse culture from an initial population of 100 to 4,120 individuals in 322 days.
