- External morphology
23 mm x 21.6 mm. Small processes on outside of oral hooks, and behind the aboral region.
Specimen found attached to roll of project foam sheets. Discovered in Osawatomie Kansas in 2019 by amateur occlupanologist T. Friend. Large flexible arms around a large oral groove distinguish this thin yet sturdy occlupanid. S. hiatus has also been observed in other unique host entities such as quilt batting.
