The ventral epithelium is ciliated across the entire width of the body, thus forming a broad creeping sole. The dorsal epithelium is only ciliated in the anterior region. At the level of the pre-pharyngeal region, the epithelium is 41 µm high on the dorsal side, 36 µm ventrally and 38 µm at the body margins. Erythrophilic granular glands open through the entire epithelium but a glandular margin is absent. Abundant rhabditogenic cells traverse the entire epithelium, being much more abundant on the dorsal side than on the ventral. In the cephalic region, cianophilic granular secretions traverse the latero-ventral epithelium.

In the vicinity of the proximal region of the male atrium, the efferent ducts turn dorsally, then curve to the sagittal plane, penetrate horizontally the common muscle coat, communicate with each other, and open into the ejaculatory duct (

The apical portion of its cells is inclined towards the opening of the duct. Scarce cells with an erythrophilic granular secretion open onto the lumen. The ejaculatory duct is surrounded by a one-fiber thick circular muscle layer, followed by a 10 µmthick layer of longitudinal fibers.
