First Records of Male and Swollen Females of Two Species of Achlysiella (Nematoda: Pratylenchidae)

Males and swollen mature females of Achlysiella trilineata magniglans were discovered for the first time in Australia. These life stages confirmed that both species show well-marked sexual dimorphism anterior region body, with males having reduced cephalic frameworks, stylets, oesophagi. A. displayed an extreme reduction style such only cone could be seen, rest esophagus was barely visible. In species, had postmedian vulvae, branch ovary longer than posterior branch. magniglans, disparity length more pronounced, vulva posterior. The finding classification rather Radopholus. Vermiform have large dorsal oesophageal glands short ovaries. Justifiably, other Radopholus these latter features (R. brevicaudatus, R. capitatus, vacuus) should also moved to Achlysiella.
