Other Notes

Individuals pictured from the Caribbean are duller than ones from the Eastern Atlantic with less contrast between the red and white. Further sampling is needed to determine if they represent S. hastatum, a hybrid of some sort, or an undescribed species. It does not closely resemble any other species from the region.
