Morphology and Anatomy:

Female:

Small body, slightly ventrally arcuate after fixation, tapering at both extremities
Cuticle thin, smooth, without somatic setae. Longitudinal striations absent; lateral fields not visible.
Lip region rounded or slightly flattened, continuous with body contour. Labial and cephalic sensilla inconspicuous.
Amphidial apertures small, located at one lip diameter from anterior end.
Stoma isomorphic, tubular with non cuticularized cheilostom, small gymnostom and long moderately cuticularized stegostom with a relatively larger dorsal denticle and two subventral denticles located at anterior end of tubular stegostom.
Pharyngeal sleeve surrounding stoma at level of denticles. Pharyngeal corpus cylindrical, muscular continuing into a rounded to pyriform basal bulb with slightly to moderately thickened valve plates.
Nerve ring encircling pharynx at 56.3-60.1% of its length from anterior end. Secretory-excretory pore not visible.
Cardia non glandular. Intestine with thin walls and narrow lumen. Rectum 0.8-1.0 times abd.
Didelphic, amphidelphic. Ovaries antidromously reflexed, on right side of intestine.
