Do types have to be “typical” of a species?

No. The purpose of a type is purely nomenclatural, i.e. to determine the application of names. Types do not need to be typical in the sense of representing an average of the range of variation of a taxon, nor do they need to be a particular sex or life stage, or even a whole specimen.
