Question about genera/species diversity?

Question about genera/species diversity?

If I just have a list of genera and species by State, is there a rudimentary way to calculate diversity without having any count of individuals?

edit: How about if I’m comparing two States but one state has more genera but less total species, which one would be more diverse overall?

For example:

Washington has 5 Genera but 24 species, while Colorado has 7 genera but just 8 total number of species

Is there a calculation to keep Genera diversity in mind at the same time?

In other words, is genera richness important?
