- - - superfamily ''family'' - - - subfamily - - - tribe - - - subtribe ''genus'' - - - subgenus ''species'' - - - subspecies The rules in the 'Code' of the ''ICZN'' apply to the ranks of superfamily to subspecies, and only to some extent to those above the rank of superfamily. In the "genus group" and "species group" no further ranks are allowed. Among zoologists, additional ranks such as species group, '''species subgroup''', '''species complex''' and '''superspecies''' are sometimes used for convenience as extra, but unofficial, ranks between the subgenus and species levels in Taxa with many species (e.g. the genus '' Drosophila ''). Ranks of taxa at lower levels may be denoted in their groups by adding the prefix "''infra''," meaning ''lower'', to the rank. For example ''infra''species or ''infra''subspecies. Infraspecific taxa then include all divisions of the species into subspecies or lower taxa. Names of zoological taxa
