Two new species of Hirschmanniella Luc and Goodey, 1963 (Nematoda: Pratylenchidae) with a key to the nominal species

Abstract

Hirschmanniella anchoryzae n. sp. from Canada and Hirschmanniella areolata n. sp. from Hong Kong are described and illustrated. The former is characterized by a flattened head, stylet length of 16–17 μm, an elongate–conoid tail with 60–88 annules, ending in an axial mucro, and location of the phasmids 37–57 μm from the tail terminus. Hirschmanniella areolata n. sp. has a hemispherical head, stylet length of 24–27 μm, complete areolation of the lateral field, a tail with 48–61 annules, ending in a ventral mucro, and phasmids 22–29 μm from the tail terminus. Spicule lengths from both species range from 28 to 31 μm. A key is presented to 24 nominal species of the genus.
