Deirids, when present, at a level where the lateral field has only four lines. Tail medium sized (c’: 2-4) conoid, never with thickened cuticle in distal portion. Labial region continuous to slightly offset. Scanning electron microscope face view typically with oval labial disc surrounded with six-sectored first lip annulus, submedian sectors somewhat flattened. Labial region annuli interrupted by longitudinal striations or grooves. Stylet generally medium sized, 20-25 µm long, sometimes shorter (10 µm) or longer (up to 40-50 µm), cone sometimes needle shaped. Males spicules without well developed velum, cylindroids, blunt-ended. Gubernaculum not protruding from cloaca” From Fortuner and Luc, 1987 and Mai et al. 1996.
