The figures and measurements are almost sufficient to describe this tiny species. The striae are fine and are interrupted on the lateral fields by two distinct wings. The front ovary is on the right, the rear on the left, side of the body. The eggs are huge and at times the ovaries are crowded until the reflexed portion passes the vulva. Fig. 18a-b. This active little species is one of the most common nemas found in the mountain soils. About twenty specimens in this collection.
