This genus is in need of revision. Most, but not all, publications give the name Berthellina engeli to the orange Berthellina from the east Pacific and the Atlantic. See Lucas Cervera's message suggesting that Berthellina quadridens is the correct name for Caribbean specimens, and second message suggesting that east Pacific animals were B. ilisima.
