It is about 30 μm long and seems to consist of a pyriform to club-shaped proximal part, 10 μm long originating on the bursa, and a slender distal tube of 20 μm. Both parts appear to be separated by a sphincter. The tubular part seems provided with a very thick tissue, of which the exact origin could not be determined. It could not be seen whether it connects the bursa to the female duct as described by Willems

One difference concerns the position of the pharynx and the genital organs. While all reproductive structures of the East African specimens are located just behind the pharynx (which is situated in the first body half), male and female organs of the Andalusian specimen occupy a large fraction of the caudal body half behind the centrallylocated pharynx. Despite this difference and awaiting the availability of new material, we prefer to preliminarily assign the specimen from
