Classification:

Type species of the genus is Mitoaxonchium basalticum Yeates, 1973

      Back to Top

Morphology and Anatomy:

• Body length < 1mm
• Lip region conoid, continuous with  body contour; lips amalgamated
• Amphid aperture oval, narrow
• Odontostyle thin with a small dorsal thorn at posterior end of aperture
• Basal expanded part of esophagus more than half the esophagus length, without a sheath of spiral muscles, the two parts separated by a constriction; dosal gland nucleus very posterior.
• Tail filiform

Note: Yeates (1973) originall described a thin spiral sheath over the cylicdrus of the esophagus and considered the genus to be in the family Belondiridae.  Siddiqi (1982), after studying specimens, decided that the "spiral sheath" was an artefact and  transferred the genus to the family Swangeridae.
