Description (from Thorne, 1929)
    Cuticle thick with exceedingly fine striae.  The amphids are elongate oval markings one-eighth the head width and have deep inner connections plainly visible from a lateral view.  No papillae or setae are visible.  At the opening of the pharynx are three refractive denticle-like organs similar to those of Ironus.  The eggs are three to four times as long as the body width and usually crowd the ovaries out of position.  The long tapering tail ends in a very prominent pointed spinneret four times as long as wide.
    This rare species has been collected by the writer only from high mountain soils.  Three specimens were in this collection.
