Technical Abstract: A nematode isolated from Formosan termite heads in unthrifty colonies at the USDA Formosan Termite Research Unit, New Orleans, Louisiana, was determined to be a new species of Oscheius. The SEM face view showed lips with unusually deep grooves between lip sectors. The hermaphroditic population was compared to other live species with morphometrics, mating and molecular characterization. Gene sequences of the D3 segment of the LS28SrRNA gene were generated for the new species and related species and genera such as Dolichorhabditis. The alignment indicated its closest molecular relative to be the amphimictic species O. insectivora. However there were 16 apomorphic sites out of 283 alignment positions that characterized the new species.
