Lips fairly well separated from each other and set off from body by a weak to fairly strong constriction. Lips fairly angular with bulnt or pointed papillae barely to moderately protruding. Amphids funnel-shaped, 5-7u wide at opening. Cuticle faintly annulated; tichkness at mid-bidy 2.0u. Cuticle thickness at head same as at mid-body; thickness at tail twice as great. Cuticle divided into thin outer layer and thicker inner layer. Lateral cord width 12u.
Spear length 14.4u. Width of spear 2.1u. Spear aperature 36 % of spear length. Spear extension length obscure. Guiding sheath slightly everted when spear is completely retracted; anterior attachment of sheath ring-like. Esophagus enlarges gradually between narrow anterior and wide posterior portions; enlargement begins at 43% of esophagus length from base. Cardia cylindrical or conical, 8-17u long. Intestine 5-6 cells in circumference. Rectum length 45u. Anal body diameter 23u. Tail curved ventrally 30-90 degrees from body axis. Caudal papillae obscure.
