Morphology and Anatomy:

Lip area flattened anteriorly, characterized (with SEM) by the complete fusion of the lip sectors with and by a distinct rounded oral disc.

The dorsal esophageal gland opening is situated at some distance (6 µm) from stylet.

The dorsal gland and one subventral gland form a large compact lobe overlapping the intestine dorsally and laterally. The other subventral gland forms a short ventral lobe. The three esophageal gland nuclei are situated posterior to the conspicuous esophago-intestinal valve.

Deirids absent.

Female: Posterior genital branch reduced to a postvulvar sac.

Phasmids on the posterior half of tail.

Tail length about twice the anal body diameter. Cuticle not markedly thickened at tail extremity.

Male: Secondary sexual dimorphism weak, affecting the esophagus, slightly reduced in male.

Gubernaculum not protruding.

Caudal alae terminal.
