What if an author refers specifically to an illustration of a single specimen when naming a species (illustrated but not named in the original publication), while also including habitat and phenology in their description. Indicating that the author was familiar with the species and could have based the description on further material.

If this potential material indeed exists and is ever found, would it be type material?

    Use of the word "unique" is a clear statement that the stated type is 
    the only specimen known to the author.
