in length. Its diameter remains constant until half of its extension, where it widens slightly until reaching the base. The base of the peduncle does not have rests of sediment nor tunic projections, probably because it was anchored to hard substratum. The tunic is transparent, thin and completely free of epibionts and exogenous material. Its consistency is extremely feeble. Both apertures are on the same side of the animal. The oral aperture is located a short distance from the peduncle. The atrial aperture is located approximately half-distance between the peduncle and the posterior region (

). The oral tentacles are long and filiform. In total, there are 104 oral tentacles, of two alternate sizes, disposed in a circle. The pre-pharyngeal band is circular, with smooth borders. It is composed of two lamellae. With a short “V” it surrounds a “C”-shaped dorsal tubercle (

). The dorsal lamina is composed of triangular languets. Strong muscular bands run through the dorsal region, from the oral to the atrial aperture. They extend from the medial dorsal region until ⅓ of the body, ending abruptly. Thinner circular muscles are distributed around both apertures. Transverse rows of branchial spiral stigmata, each with two to three coils, extend along the body axis. There are approximately 49 transverse rows on the left side and 45 on the right side. Each stigmata is crossed by two to four thin radial vessels. T-shaped papillae arise from the transverse vessels, most commonly at the intersection between stigmata. Some also arise at a mid-distance from a stigma. In some regions of the branchial sac, these papillae give support to longitudinal vessels. When present, there are one or two longitudinal vessels per stigmata (

). In total, there are 73 longitudinal vessels on the right side of the branchial sac and 80 on the left side. The gut-loop is under the branchial sac, displaced to the right side of the body. The small barrel-shaped stomach has 20 longitudinal folds. The rectum runs parallel to the dorsal lamina and to the gonoducts, whose openings lie next to the anus. The anal border is smooth. Testis follicles and ovaries are distributed in the gut-loop, the former being spread over the proximal end of the former.

populations from the northern and southern hemispheres. One of them, (the number of transverse vessels) is not considered, because it might be associated with animal growth. Our specimen possesses one of the characters signaled by these authors for the southern hemisphere populations (shape of the pre-pharyngeal band). The remaining character (number of longitudinal vessels or papillae), coincides partially with what has already been described for those populations. As signaled by Sanamyan K. & Sanamyan N. (2005), more samples are required to definitively confirm this hypothesis.
