Araguanema mutabile is characterized by:

•  having both vesicular and fimbriate somatic sensory organs, numbers of fimbriate organs differing among specimens.
• four cephalic papillae,
• mouth aperture small, lips absent, short, wide, cuticularized stoma,
•  muscular, clavate pharynx with isthmus and basal bulb,  with the nerve ring encircling the isthmus, 
• anus wide with long protruding fibers

 It differs from the type species of the genus (A. venezuelae) in:

•  the shape of the pharynx,
• indistinct vs distinct amphids,
•  stoma with cuticularised vs non-cuticularised walls,
• different arrangement of the sensory organs,
• more numerous eggs with ornamented vs smooth egg-shells
