This species was very fast moving and fairly uncommon in our samples. Due to a lack of available specimens, only a single mature animal was fixed for histological sectioning. Unfortunately, this single specimen is slightly damaged around the gonopore, and as such, it is not possible to determine whether it is solely a male gonopore, or a common gonopore that also opens to the seminal bursa.
