Lip region slightly offset, carrying 6 + 4 papillae and two round amphids. Three pairs of asymmetrical lips, one dorsal and two ventrolateral. Pairs of lips separated by U-shaped primary axils without guarding processes. Each pair with a shallow incisure demarcating a secondary axil. Each lip asymmetrically rectangular with a smooth margin.

Pharyngeal corpus cylindrical; isthmus narrow, often wrinkled, and not clearly demarcated from corpus; bulb oval, with valves.
