Rhips orientalis Male: A. total body; B. head

Drawings from Kulikov, 1993

Females:

Ref:  Kulikov, 1993

  
   

  • Body long, slender, tail narrowly attenuated
  • Cuticle stiated transversally except for cephalic capsule and tail tip; between head and mid body, anterior wedge of each annulus overlaps posterior edge of preceding annulus; posterior to mid-body posterior edge of each annulus overlaps anterior edge of the next.
  • Lateral line begins about 100 um from posterior margin of amphidial pouch, broadening to maximum width near mid-body and then narrowing and disappearing in tail region.
  • Sublateral fields appear as narrow strips of non-annulated cuticle with maximum width in posterior body; they disappear in posterior 25% of tail.
  • Cuticle thinner in head-end with 6 cap-like projections of thick cuticle radially arranged between cephalic sensillae. Inner sclerotia inside each cuticle ring: quadrangular ones close to anterior end or elliptical ones throughout the body.
  • Cephalic setae in two circles. Cervical setae at 3 body diameters from abase of stoma.
  •  Thin-walled stoma vestibulum supported by 12 rod-like cuticlular projections.
  • One large hollow tooth and two small sublateral onchia.
  • Pharynx slightly broadened posteriorly.

Males:

  • Monorchic, testis outstretched on right of intestine.
  • Spicula in two arches "double jointed"
  • Gubernaculum with lateral L-shaped pieces.
  •  Tail length 245-270 um.
