Taxa heretofore referred to as americanus, bicolor, major, seminudus and shealsi are all placed in a single superspecies, Gamasellodes bicolor Berlese. The superspecies includes two allospecies, G. [bicolor] bicolor (Holarctic) and G. [ bicolor] seminudus (Africa). G. americanus from North America is treated as a probable subspecies of G. bicolor, whereas major and shealsi are regarded as synonyms of G. (bicolor) bicolor. Gamasellodes garmani n. sp. is described from a Connecticut apple orchard.
