Not biologists, saw the picture on a museum and tough it deserved some attention. I believe it became custom to add the name of the person who discovered the species and the year to the scientific name as can be seen here and in the message at the side of the picture on te museum.
The small ant is a specialized predator of spider eggs. I don't think they have any relationship, the photographer just wanted to show the contrast between their size and took a cool picture.
