|

Body elongated, strongly annulated until mid-body. Posterior end also strongly annulated. Annulations of the anterior part of the body with triangular smooth outline. No somatic setae are visible. Cephalic region clearly offset followed by a narrow constriction about 50% narrower than the section behind this constriction. Four cephalic setae are present. Amphids vesicular, with a blistered amphidial fovea. Buccal cavity small and unarmed. Pharynx surrounded by many glands. Many pigment spots present, located at the end of the pharynx and beginning of intestine. Pseudocoelomocytes present, at the end of the pharynx and beginning of the intestine. Testes reflexed. Anterior testis well developed, posterior one much smaller. Spicules just slightly curved. Gubernaculum with caudal apophysis. Three setae inserted on elevations of the body cuticle, present as pre-cloacal supplements, plus one additional post-cloacal supplement. Small phasmata-like structures located laterally at the last posterior third of the tail region, on each side of the body. These structures can easily be overlooked. Three caudal glands contained in the tail. Tail conical, long with spinneret.

Similar to males in most aspects, although generally longer. No sexual dimorphism detected. Reproductive system didelphic, amphidelphic, with reflexed ovaries. Reproductive system with a clear posterior ovary and a smaller anterior ovary. Vulva with non-protruding lips, positioned close to the mid body, slightly posteriorly in most cases. No perivulvar glands observed. Vagina transverse. Uterus not well-distinguished, appearing to be uniform. Oviduct indistinct; ovaries antidromously with reflexed tips. Phasmata-like structures, laterally at the last posterior third of the tail region, on each side of the body, larger than in males. Female tail conical, longer than in males. Terminal spinneret with same morphology as in males but slightly elongated.
