Officially there are three species in the genus. Some claim that edulis is a subspecies of adspersus, others believe that they are separate species. At one time, edulis was known as P. adspersus angusticepts and P. a. edulis. Sounds confusing? There's more... recently, many species of frogs commonly known as "dwarf pyxies" have been moved into the genus Tomopterna. No matter what species, it is a good looking frog
