A new species of Sphaeronema is described. S. whittoni females are distinguished by their round stylet knobs, vulval lips flush with the body, lack of cuticular pattern, and large size. Males and second stage larvae differ from other described species in the shape of stylet knobs and body size. In 1956 specimens of Sphaeronema were collected by Mr. Gilbert M.
