Morphology and Anatomy:

 

Females:

  •  Body long, slender, tapered towards the extrem1t1es,
  •  Cuticle finely annulated, covered by an almost continuous layer of fine concretion particles and with prominent protruding concretion masses,
  • Somatic setae stout with pointed tip; usually paired, inserted on low peduncles. Five sub-dorsal setae on both sides and three sub-ventral setae on the right side, two on the left body side.  were observed. The setae become longer posteriorly.
  •  Head about as long as wide. C
  • Cephalic setae inserted on high peduncles just anterior to halfway the length of the head.
  • Amphids broad, rounded vesicular structures covering the lateral posterior head-region and surrounded and covered by a layer of concretion.
  • Ocelli, light brownish oval pigment spots, situated opposite the 4th and 5th row of concretion masses.
  • Stoma small, thick-walled.
  • Esophagus cylindrical, slightly narrowing posteriorly.
  •  Intestine gradually widening posteriorly to a broad granular cylinder, with many small globules.
  • Didelphic-amphidelphic. Spermathecae obscure.
  • Vulva situated halfway along the body length.
  • Tail long, slender, with prominent long, fine end and spinneret.
