    The correct citation is: Eldredgeops rana (Green, 1832)

     

    The parentheses around the author citation indicate it is not the original taxonomic placement. 

    Green originally classified it as Calymene.  Emmrich 1839 subsequently established Phacops.

    Although Struve 1990 established the genus Eldredgeops, Green 1832 always retains priority.

    I have updated it. Is it correct now?

     

    Thank you for clarifying! I was wondering about that when I was filling in the field, but didn't honestly know which to cite.
