Fennah (1954) formed family Acanaloniidae as he revised the Issidae. Gnezdilov (2012) excluded all Old World genera from Acanaloniidae, transferring them to other families. Thus Acanaloniidae contained four genera: Acanalonia, Batusa, Chlorochara, and Philatis. All four are found in the Neotropics, while Acanalonia also ranges into the United States and Canada.
In a subsequent article of the same year, Gnezdilov (2012b) moved three species of Acanalonia into a new genus, Bulldolonia. He commented that genus Acanalonia remains polyphyletic.
