All specimens possess long submedian body setae and thus belong to the typical form. These setae reach a length of 7 \L in mid-body, or nearly one-third of the corresponding body width. The head end bears six distinct lips. The cephalic setae, directed anteriad, measure 2.5 (i; the longer subcephalic setae 10 [x or 0.8 head widths; the shorter subcephalic ones are 6 \i long. Diameter of amphids 4- 6 |x or one-third of corresponding body width. The distance from the amphids to the head end is 21-28 JJ. or 1.5-1.9 head widths. The posterior third of the oesophagus is sligthly thicker than the remainder. The rectum is two anal body widths long, the anterior half is inflated.
