Long cylindrical body; no musculature on the oral siphon and on the left side; musculature on the right side formed by short parallel fibers on the dorsal and ventral margins; oral tentacles project from a delicate membrane joining them by their bases; dorsal tubercle absent; accessory apertures concentrated near to the neural gland; 58–78 longitudinal vessels on the right side and 47–64 on the left side of the pharynx; 3–5 stigmata per mesh; filiform primary papillae on the first anterior transverse vessel; elongated or sac-like dilation at the rectum; ovary inside the primary intestinal loop, ramified on the intestine wall; gonads of both sexes are not found at the same time.

In the field the oral siphon projects 1.0–2.0 cm from the bottom and is easily recognized by the pale yellow color and by its shape, with the aperture diameter smaller than the siphon itself (about 1.0 cm). Numerous yellow papillae project from tunic around the siphons. The animal is attached to coral fragments and shells by the left side which is very delicate and easily broken when attempting to remove the animal from the substrate. The tunic is yellow and transparent; on the right side it is thicker (2.0 mm) and gelatinous, with some protuberances. Blood vessels are very ramified and have swollen blind ends which appear as small yellow papillae on the surface of the tunic.</paragraph>

On the right side of the esophageal aperture, the transverse vessels form long languets. The pharynx has 58–78 longitudinal vessels on the right side, 47–64 on the left side and 192–317 transverse vessels, is not pleated and with few stigmata in the meshes (3–5). Primary papillae are bilobed, and only those on the first anterior transverse vessel have a filiform lobe and longer; intermediate papillae are very small, button-like or completely lacking. Parastigmatic vessels were not seen.

The species is apparently sequentially hermaphrodite: only the ovary was developed in individuals collected in June and August, while only the testis was visible in those collected in December and February. The ovary is mostly located inside the primary intestinal loop. Outside the loop it may branch on the intestinal wall at the top of the primary loop. From the inside, there is a portion inside the primary loop and also a portion on the rectum at the extremity of the secondary loop, which do not show ramifications, instead it is more cauliflower like. Oocytes are

The testis has long and little ramified follicles covering the wall of the ascending intestine and of the intestinal dilation, both externally and on the atrial cavity side. The sperm duct has many small apertures spread on the body wall anterior to the oviducal aperture (
