Amphids not observed. Annules fine about um at mid-body. Lateral field with four lateral lines, hardly evident. Spear moderately slender, um long with small basal knobs um wide. Excretory pore um from anterior. Oesophagus poorly preserved, about 68 um long; median bulb ovoid, valves not observed, centre at about 59% of oesophageal length. Testis 138 um long, occupying 32% of body length, bursa adanal, about 19 um long, with fine crenated margins. Tail tip pointed. Remarks. No conclusion can be reached on the specific identity of this specimen. It is close to , but differs by its shorter body length, spicules and tail.
