Notes

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.
