Tylenchus davainii Bastian, 1865 .

The coarse striae are interrupted on each lateral field by a wing area one-fourth as wide as the body, bordered by crenate margins with the wings appearing as two bright lines between them. The esophagus is typical, the median bulb being strongly developed to three-fifths the neck width. The renette pore is a striking feature, being heavily cutinized. The deirids can be seen very distinctly almost opposite the excretory pore. Fig. 1 c. The cells of the rather narrow intestine are filled with coarse granules. The anterior ovary is the only one developed, the posterior being less than one body width in length. The tails of both sexes are similar in form, being conoid to the pointed terminus and strongly arcuate, especially in the last fourth. Fig. 1 b.

One of the most numerous species in the collection, about 200 specimens being present. Fig. 1 a-c.
