Abstract: The morphology of Heligmosomum costellatum, a nematode of field mice (Microtus epiraticus), was described by scanning electron microscope. The scanning electron microscopic view of this nematode revealed that the anterior end was surrounded by 2 cephalic vesicles. The 2 copulatory spicules of the male were enveloped in membrane and the male bursa was large. The female posterior end was characterized by a caudal spine. The body of this parasite had transverse ridges.
