"Orthalicus reses" has two subspecies:
- "Orthalicus reses reses" (Say, 1830) - Stock Island tree snail
- "Orthalicus reses nesodryas" Pilsbry, 1946 - Florida Keys treesnail
It is generally thought that the two subspecies of "Orthalicus reses" do not interbreed due to anatomical incompatibility. However, Emmel and Perry (2004) recommended that if the two "Orthalicus reses" subspecies prove to be as genetically invariant as was observed in their study, the groups should be considered a single taxon
