Head with six distinct lips, each with one small papilla. Longer cephalic setae 6–8 µm, shorter setae about 4 µm. Width of head 19 µm. Buccal cavity 8–10 (9) µm wide and 10 µm long; total depth of stoma (buccal cavity and pockets) 20–26 (23) µm; two pockets separated by short isthmus, each pocket with one teeth, distance between tops of teeth 9 µm. Amphid openings at level of bottom of buccal cavity or at level of first pocket; amphid diameter 4 µm, approximately one-sixth part of corresponding body width. Reproductive system didelphic, amphidelphic; ovaries reflexed, oocytes arranged in double rows in germinal zone; only two females with mature eggs in uterus.
