Very small (<< 6 mm long) and rather stout species ( Figures 12 View Figure 12 and 13 View Figure 13 ). Amphids more distinctly spiral than in other species. Males with prominent enlarged GSO in ventral post-pharyngeal region, protruding as 19 bumps. The species is remarkable for small (2 µm long) setae situated close to the submedian subcephalic setae. Cephalic capsule very long, extending over>70% of corpus. Long corpus occupies up to a third of pharynx length, large bulbus and consequently a very short isthmus (48–55% of pharynx length). Sparse somatic setae. Tail conical with rounded tip. Male testis with conspicuous large, round cells (sperm?). Symbiotic bacteria coccobacilli, 1.3 × 1 µm.
