Gongylonema pulchrum was first named and presented with its own species by Molin in 1857.

In most examples the worm was attached to a stem, with a crank, inserted through a frame with a lever. In most examples the worm was cranked into the cork, and then a lever was pressed or pulled to extract the cork.
