Description (from Thorne and Malek, 1968)
    Striae about 1 um apart.  Lateral fields marked by four extremely faint incisures, sometimes not visible.  Lip region narrow, truncate.  Cephalic framework strongly cuticularized.  Spear about 10 um long with strong sloping flange-like knobs.  Cardia very small, conoid.  Vulva a deep transverse slit.  Vagina extending in and forward to prominent quadricolumella.  Spermatheca a differentiated cell of the quadricolumella.  Ovary outstretched, about half its length occupied by two lines of developing oocytes, almost filling body cavity.  Tail uniformly tapering to small, blunt terminus.
    Male with well developed bursa.  Spicula about 14 um long, cephalated, resting on a slender, trough-like gubernaculum.
    Boleodorus similis is immediately distinguished from B. thylactus by its smaller size and shorter, slightly arcuate tails.  From B. volutus Lima & Siddiqi it differs in the body being less arcuate and much larger bursa.
    Habitat: Strawberry field, Agricultural Experiment Station, Brookings, S. Dak.
