Although Steinmenn (1989) attributes Carcinophoridae to Popham (1965) and Carcinophorinae to Hincks (1954), the International Code of Zoological Nomenclature's Principle of Coordination (Art. 36.1) requires that both be attributed the earliest, to Hincks (1954): "A name established for a taxon at any rank in the family group [ranks superfamily through subtribe at least] is deemed to have been simultaneously established for nominal taxa at all other ranks in the family group; all these taxa have the same type genus, and their names are formed from the stem of the name of the type genus [Art. 29.3] with appropriate change of suffix [Art. 34.1]. The name has the same authorship and date at every rank"
