This image is perfectly fine where it is (in the genus entry for Haworthia) but if you'd like to move it to a specific entry, it would belong here:
Horse's Teeth (Haworthia truncata)
For what it's worth (reading the caption) the database treats maughanii as a variety of truncata, but we can sidestep the issue of what variety it is but using the species entry for this image.
@HamiltonSquare if you would like, I can move this image for you, or we can leave it where it is. Please let me know what you think.
