Ghost Bulimulus = Bulimulus sporadicus

There is a new invasive species in Florida, which has been reported for some time as the “ghost Bulimulus” or ‘Jacksonville Bulimulus‘. Thanks to the many efforts of Bill Frank and Harry Lee, and the ability of David Robinson to compare specimens with those that were previously reported as B. sporadicus (d’Orbigny, 1835) from Houston, we now know that the Florida populations belong to the same taxon. Some authors regard it as a subspecies of B. bonariensis (Refinesque, 1833).
