One or more additional Aphaostracon species have been reported from springs in Florida, including Bugg Spring, De Leon Springs, and Green Springs. The snails from the three springs have not described in an authoritative publication, and it is not known if they belong to one, two, or three species.{{Cite report |last=Shelton |first=Douglas N. |title=The Rare and Endemic Snails of Selected Springs Within the St. Johns River Water Management District |date=September 2005 |url=https://www.academia.edu/11577131 |publisher=St. Johns River Water Management District |pages=5–6}}
