Female. Body remaining nearly straight when relaxed by heat; truncate anterior and attenuated posterior termini.  Labial region with distinct lips and nerve channels, set off by depression from remainder of body.  Ovoid buccal cavity about one and two-thirds longer than wide, with three large, equal-sized teeth at posterior third of stoma.  Amphid apertures obscure. Esophagus with nerve ring and excretory pore at anterior third, terminated by tuberculate valve.  Didelphic with distinct valves between uterus and oviducts.  Tail attentuated, conoid, without caudal glands and spinneret.  Six pairs of caudal pores usually visible (four dorsal pairs, one each at levels of rectum, upper quarter, middle, and lower quarter of tail;  two ventral pairs, one each at middle and lower quarter).  Also two pre-anal pairs (one dorsal and one ventral) in vicinity of tail.

Male.  Similar to female in details of labial, buccal, and essophageal regions.  Tail region with fifteen equally spaced supplements beginning near the cloacal opening.  Spicules slender, strongly arcuate; gubernaculum crescent-shaped and sigmoid with most areas thickened; small bifurcate accessory organs also occur.  Arcuate tail with conoid anterior and spicate posterior portions, without caudal glands or spinneret; caudal pores were not observed.
