:Small nematodes, 358 to 504 um long.
-
Cuticle annulated; annuli about 2 um wide at midbody.
-
Lateral field occupying 14 to 22% of the midbody diameter, with four
incisures
-
Lip region with six lips: the subdorsal and the subventral are very
refractive and hook-like (4to 5 um high); the lateral lips are
membranous, high and with dentate margin, not easily observed under
LM
-
Stoma rhabditoid. Buccal prism with straight walls, very long and
narrow. Stegostom lacking glottoid apparatus.
-

basal bulb together; procorpus cylindrical and metacorpus swollen,
almost as long as wide.
-
Basal bulb spheroid, with well developed valves at its middle.
-
Cardia hemispherical, surrounded by intestinal tissue.
-
Excretory pore at 77 to 92% of neck length, at level of posterior
portion of isthmus or basal bulb. Deirid at basal bulb level, at
81 to 97% of neck length.
-
Reproductive system didelphic-amphidelphic. Anterior genital branch
dextral (on the right side of intestine) and posterior branch
sinistral (on the left).
-
Ovaries with a flexure, rarely straight.
-
Uterus short, less than the corresponding body diameter long.
-
Vagina with thin walls, extending inwards one-third of body
diameter.
-
Rectum 0.8 to 2.0 times anal body diameter long.
-
Tail conical-elongate to filiform, ending in acute tip. Phasmid at
11 to 12% of tail length.
