Abstract
In the present study, evaluations of the nominal species and descriptions (H. parvus, H. intermedius, H. insignis, H. microdoratus and H. brevicaudatus) are made of five new species. H. squamosus is proposed as a species inquirenda; H. mangiferae is judged a valid species. H. litchi and H. birchfieldi are synonymized with H. mangiferae and H. ureshinoensis with H. kanayaensis. H. strictathecatus is considered a valid species. A key to the species of the genus is given. The limitation of use of male diagnostic characters in a mixture of populations of Hemicriconemoides with some other criconematids is discussed. The life cycle of H. chitwoodi has four complete molts; one in the egg, three in soil, two of which have spines. The adult female has a sheath cuticle from an incomplete fifth molt.
