Rotylenchus rhomboides n. sp. is characterized by the presence of a rhomboid-like widening of the mid-ridge of lateral field at the level of vulva, a feature previously unknown within the genus. The population of the new species, composed only by females, has a rounded labial region with 4 to 5 annuli, robust stylet (31{\textendash}37μm long), short dorsal esophageal gland (9{\textendash}19μm) overlap of the intestine, vulva located slightly posterior to mid-body, and hemispherical or rounded tail shape with large phasmids located 3 to 5 annuli anterior to the level of anus. The hierarchical cluster analysis based on morphological features indicated that the new species closely resembles R. corsicus, R. gracilidens, and R. rugatocuticulatus. The DNA analyses of the D2-D3 of 28S rDNA, ITS rDNA, and COI mtDNA sequences of Rotylenchus rhomboides n. sp. show a close relationship with R. buxophilus, R. goodeyi, R. laurentinus, R. pumilus, and R. incultus, all of which can also be differentiated from the new species by morphological features. The combination of morphological, morphometric, and molecular characteristics confirmed the new species and the first report of R. buxophilus on yam (Dioscorea tokoro) in Belgium.}, keywords = {28S{\textendash}D2D3, coi, Dioscorea tokoro, Hierarchical cluster, its, morphology, Musa basjoo, phylogeny, Plant-parasitic, Rotylenchus, Systematic, taxonomy}, issn = {0022300X}, doi = {10.21307/jofnem-2019-023}, author = {Nguyen, Huu Tien and Trinh, Quang Phap and Couvreur, Marjolein and Singh, Phougeishangbam Rolish and Decraemer, Wilfrida and Bert, Wim} } @article {Nguyen2019b, title = {First Report of Scutellonema brachyurus (Steiner, 1938) Andrassy, 1958 and Occurrence of Meloidogyne incognita (Kofoid \& White, 1919) Chitwood, 1949 in Belgium}, journal = {Journal of Nematology}, volume = {51}, number = {2018}, year = {2019}, pages = {1{\textendash}6}, keywords = {by, com, e-mail, global warming, gmail, Hedychium greenii, mtDNA, Musa basjoo, nad5, this paper was edited, tqphap}, issn = {0022-300X}, doi = {10.21307/jofnem-2019-062}, author = {Nguyen, Huu Tien and Trinh, Quang Phap and Couvreur, Marjolein and Singh, Phougeishangbam Rolish and Decraemer, Wilfrida and Bert, Wim} }
