Archaphanostoma marcusi Notes
Hooge M.D. & Rocha C.E.F. 2006 (citation) - p. 22, "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.
Our species is placed in the genus Archaphanostoma due to its possession of the diagnostic character—a syncytial
seminal bursa. A. marcusi differs most substantially from the other three known species of the genus by its
possession of a bursal nozzle. A disjunct nozzle is an uncommon occurrence among members of the Isodiametridae,
but is present in Aphanostoma bruscai Hooge and Tyler, 2003 (see also Petrov et al. 2006)."
