Adult Lt 440–486 µm; L to PhJIn 162–166 µm at U38–U33 (Fig. 18). Body medium-short, slender; head sculpted, with a narrow band of circumcephalic cilia and shallow lateral lobes at U05, but no tentacles; neck constrictiongreatest along the mid-pharynx; trunk broadest along the mid-body, thinning gradually to the caudal base; caudum is slightly cleft, incised from its tips to U98, bearing a medial cone. Widths of apex /head at turban /trunk at PhJIn /mid-gut /furcal base, tips, and their locations along the body length are: 46 /37 /47 /49 /24, 39 µm at U06 /U16 /U33 /U52 /U96, U100. Glands 36–37 per side, small (diameter 3–4 µm), scattered and inconspicuous.
Adhesive tubes: TbA 7 per side, inner-most shorter than the others, occuring on fleshy hands that insert at U11; TbVL 9 per side (L 10–14 µm), with 1 along the fore half at U11 and 0 along the rear half of the pharynx, and 8 evenly spaced and symmetrically arranged along along the intestine at U40–U91, none behind the anal opening; ‘cirrata’ [Seitenfüsschen] tubes are present at U35 but short (L 9 µm); TbP 7 per side, lengthening from medial to lateral (L 6–10 µm), arrayed along the rear edge of each lobe.
Ciliature: Mouth is surrounded with short sensory cilia (L 4 µm), with 2 pairs of longer vibratile cilia (L 8–10 µm) per side inserted at the points of head sculpting; ciliary hairs (L 12 µm) form a circumcephalic band at U05; sensory cilia of similar length (L 14–16 µm) occur on the trunk in lateral and dorsal columns, with 20 and 16 per side, respectively. Ventral locomotor cilia (L 8 µm) run rearward in 2 longitudinal bands that trace the lateral body margins, remaining separate throughout, the cilia occurring in transverse rows.
Digestive tract: Mouth terminal, of medium width (18 µm diameter); buccal cavity mugshaped, shallow; walls lightly cuticularized; pharynx broad throughout, with conspicuous basal pharyngeal pores; intestine broadest in the fore-gut, narrowing gradually toward the rear, with a slight bulge at the ventral anus at U92.
Reproductive tract: Hermaphroditic; paired testes extend rearward from the PhJIn, sperm sometimes descending in clusters to the base of the vasa deferentia, male seminal pore not seen; bilateral ovules and ova (to 71 × 18 µm) occur in the fore-gut region and develop rear to fore; neither frontal, nor caudal organs were seen.
