Nemas with unusually long, slender, pointed necks.  Enlarged portion of esophagus set off by constriction and surrounded by a sheath of muscles which may be spiral.  Anterior ovary rudimentary, posterior normal.  Tails bluntly rounded.  Males bearing a series of ventromedian supplements which may be adjacent or spaced.

Small numbers of Axonchium were collected throughout the region but the number of species was surprisingly small, only 2 being definitely identified.
