A single, continuous adhesive girdle is present at the caudal body end. A rosulate pharynx is present at about 65%. The proboscis is highly asymmetrical: the ventral tongue measures approximately 44 μm, while the larger dorsal tongue measures 61 μm in length. The proboscis armature consists of rows of small, triangular teeth. On the ventral proboscis tongue, four to six teeth are set in a single row on either side of the tongue, with the teeth increasing in size distally. These teeth have a basal diameter of up to 4 μm and measure up to 3 μm in length. On the dorsal proboscis tongue, the teeth are arranged in multiple rows. In the distal part of the proboscis, the teeth are largest, with a diameter of 12 μm and a length of approximately 2 μm. These are more or less set in a single row. In the middle section of the proboscis tongue, the proboscis teeth are small and form a field of 34 rows. At the base of the dorsal tongue, the teeth are once again arranged in a single row. In the area connecting the tongues, the teeth form another wider field of about three rows.</paragraph>

The proximal ends of the seminal vesicles lie on either side of the pharynx. The male copulatory system holds a sclerotised, conical cirrus with a length of 15 μm, armed with very fine spines. In our specimen, the proximal spines have a diameter of 34 μm in the proximal region and 1112 μm in the distal region of the cirrus. The male copulatory bulb connects to the male atrium, which is surrounded by circular to slightly diagonal muscles and leads into the common genital atrium. The common genital opening is situated at about 80%.</paragraph>

has a very similar organisation of the proboscis teeth. However, rather than two fields of spines, interrupted by a short section in which the spines are in a single row, the spines form a long stretch of three to four continuous rows. Furthermore,

mentions a tubular shape, while our specimen displays a more conically-shaped cirrus. However, this difference is likely the result of either the flattening of the specimen or the state of contraction of the copulatory bulb (or a combination of both).
