No need to resubmit, you can log in, go to the image you posted to ID request initially:

click on the Edit link to change the label, etc.
Then:
+Save changes
+click on the tag link
+find Zelia (follow the link in the comment or do a search on the genus name)

+click on [b]Move tagged image[/i] link on the left.
Very simple! (after some practice)
