Cuticle very finely annulated; annules only 1 um wide on mid-body
region. Lateral fields about 1/5 of body width, with three distinct
longitudinal bands. Head 4.5 um wide at base, with inconspicuous
striation; oral field plain. Body at base of proximal end of oesophagus
twice as wide as head.
Spear 7.5 um long, weak, 1.6 times longer than head diameter; basal knobs oval. Length of spear only 1/13 of oesophagus. Anterior portion of oesophagus (from head to posterior margin of median bulb) much shorter than posterior one, only about 40% of entire length of oesophagus. Median bulb oval with small but distinct valvula; terminal bulb piriform. Excretory pore before terminal bulb. Distance between proximal end of oesphagus and vulva 2.6 times longer than oesophagus.
Vulva-anus distance 1.2 times longer than tail. Posterior uterine sac a little shorter than body width. Tail 56 um long, 7 times as long as anal body diameter, slightly arcuate ventrally, relatively stout, tapering slowly to the rounded terminus.
Peculiarities: Body very small, hardly curved; head not separate; cuticle extremely finely annuluated; spear very short; anterior portion of oesophagus much shorter than posterior; vulva far back; tail of moderate length, nearly cylindrical, slightly bent ventrally, with rounded tip.
