Technical Abstract: Two new species of Paurodontella collected around the roots of wheat (Triticum aestivum L.) are described and illustrated. One new species is characterized by having a short cylindrical, robust body markedly tapering at both ends with an anteriorly located vulva, short post-uterine sac, lateral field with four incisures, excretory pore at the base of esophagus, fusiform median bulb and straight pointed tail with a long thorn-like mucronate terminus. The other new species has a longer and very slender body with posterior vulva, lateral field with four incisures, and short conoid mucronate tail. An identification key to 10 valid species of Paurodontella is given. A compendium of the most important diagnostic characters with illustrations of each species is included as a practical alternative and supplement to the key. The diagnosis of Paurodontella is emended and a list of all worldwide valid species of the genus is given. Additional information regarding distribution of the two new species and their importance is needed.
