- Anterior end rounded in LM but four cephalic papillae and
6 inner labial papillae visible in SEM.
- Amphidial openings are long wavy sinuous slits originating
close to labial plate, extending laterally posteriorly, reaching and
passing first body annulus, amphidial fovea spacious.
- Stylet with three knobs, slightly directed posteriorly,
conus comprising ca one-third of total stylet length.
- Pharynx tylenchoid, metacorpus ovate with small valve,
pharyngeal bulb pyriform to saccate.
- Secretory-excretory pore at metacorpus level.
- Intestine simple, rectum and anus functional.
- Reproductive system monodelphic-prodelphic,ovary outstretched,
oviduct barely visible, spermatheca rectangular with rounded corners
to ovate in shape, crustaformeria quadricolumellate, uterus simple,
