Morphology and Anatomy:

.

Female: Body spiral to C-shaped, medium sized.  

Lip region slightly offset or continuous with body, with or without annules and/or longitudinal striae.  

Labial framework and stylet medium sized; stylet knobs flattened to indented anteriorly.  

Dorsal esophageal gland opening 3  to 10 µm from stylet base.  

Esophageal glands with three nuclei, overlap intestine dorsally and laterally; intestine symmetrically arranged between the subventral glands. 

Two genital branches outstretched, equally developed.  

Lateral field with four or fewer incisures. 

Tail short, rounded.  

Phasmids enlarged to scutella erratically situated on body in lateral field, not opposite each other, anterior to anus level; sometimes one scutellum is anterior to vulva level.               

Male: Caudal alae enveloping tail, lobed in labial region.

Esophageal structures smaller in males than in females
