: Body slender, long, uniform in diameters tapering anteriorly and posteriorly. Fixation shape uncoiled. Cuticle transversally striated with fine punctation more evident on the tail region. No lateral differentiation. Few somatic setae with no fixed distribution pattern. Head conical, low lips. Inner labial sensilla papilliform, six outer-labial short setiform sensilla, four cephalic setae 5 µm or 35% of corresponding body diameter long. Short dorso-sublateral subcephalic setae present. Amphid spiral, ventrally to the centre, 3 turns. Mouth opening ventrally displaced. Buccal cavity wide, deep (18 µm), funnel shaped. Gymnostom followed by well-cuticularized pharyngostom with expanded conical posterior part. Sclerotized walls of pharyngostom with three small teeth: a dorsal tooth and two smaller subventral teeth. Pharynx cylindrical with a posterior muscular bulb. Nerve ring located slightly anterior to middle of pharynx. Secretory excretory pore located immediately after cephalic setae. Reproductive system with long vas deferens, clear patch of variable position from the level of the 4th to the 8th supplement from the cloaca. Outstretched testes anteriorly directed, anterior one to the right of intestine and posterior one, smaller, to the left. Spicules of equal size, about the same length as the cloacal diameter, slightly cephalated, bent about 1/3 of the distance from the distal end. Gubernaculum plate-like with a sclerotized rod-like internal structure at the distal half. Ten to twelve conspicuous cup-shaped precloacal supplements with external longitudinal articulated flange. Distance between the supplements variable among the males. Prominent ventral precloacal spine about 16 µm anterior to the cloacal opening. At the opening of the cloaca there is a slightly sclerotized triangular structure, which seems to be a cuticular projection. Tail conical plump, with bluntly rounded tip. Three caudal glands opening in a prominent, terminal blunt spinneret, half as wide as the tip of the tail.
