Morphology and Anatomy:

Malekus and Oriverutus both have distinctly protruding papillae in the lip region and a comparatively long odontostyle. They differ in the morphology of lips (amalgamated in Malekus versus separate in Oriverutus), morphology of the odontostyle (versus much slender, needle-like), and in having a double guiding ring.

  • Small to medium length around 0.7 mm.
  • Cephalic region slightly offset, lips withprominent forwardly-directed papillae
  • Odontostyle long, extremely slender, , longer than width of lip region.
  •  Tail conical, bent ventrally

Female:

  • Didelphic-amphidelphic.
  • Vulva not sclerotized

Male:

  • Unknown
