Trophotylenchulus
Female:
- Body obese particularly between pharynx and vulva,
tapering towards both ends, strongly ventrally curved.
- Cuticule annulated; lateral field.
- Cephalic region hemispherical continuous with body contour,
without perioral disc or transverse annuli; cephalic framework is
slightly sclerotized.
- Stylet strong, conusabout as long as shaft, basal knobs round,
slightly sloping backward, about 3 um diam.
- DEGO is situated at 3.5 to 5.0 um posterior stylet knobs.
- Procorpus amalgamated with median bulb which has elongate-oval
valvular apparatus; median bulb is 14 to 23 um in width; basal bulb
pyriform.
- Isthmus is short and narrow; nerve ring at anterior end of
isthmus.
- Excretory pore at end of isthmus at about 18-25% of body
length) at the end of isthmus; duct with wide lumen leads backward
to a large renette cell.
- Monodelphic-prodelphic. Ovary well developed, outstretched
without flexures, reaching basal pharyngeal bulb; short
post-vulval sac present.
- Spermatheca round with slightly oval sperm cells; t. V
- Vulva a transverse slit flush with body, without cuticular
flaps, at 89 to 114 um anterior to tail terminus.
- Vagina is perpendicular with body or directed anteriorly.
- Anus distinct with raised lips.
- Tail arch-shaped, curved ventrally with a finely- to
