| Abstract: | Abstract Helicotylenchus species collected from managed soils in New Zealand were identified. They were found at 159 sites. H. pseudorobustus was found at 82 of these sites, H. labiatus at 56, H. varicaudatus at 28, and H. canadensis at 4. Only 11 sites had more than one species present and most (7) of these sites had mixtures of H. pseudorobustus and H. labiatus. H. labiatus, reported only twice before, was the most common species found in cotula bowling greens. H. canadensis was restricted to sites south of 45°S. Measurements are given for 15 populations, and H. labiatus is illustrated. Characters separating the four species are given. |
