Dear Bill
Please confirm the ID of this as Jorunna zania  I nearly squashed this one as it was on top of a rock in only a small drop of water.

Locality: Pumula, KwaZulu-Natal, South Africa. Indian Ocean coast. Intertidal zone. Length: 45 mm. March 2005. Intertidal. Photographer: Valda Fraser

Dear Valda,
I am afraid I think the jury is still out on some of the species proposed by Eveline Marcus in her 1976 paper in which she revised this genus. However the two characters she used to differentiate J. zania from J. funebris are not visible in your photo, so I think it's best to leave it as J. funebris.

J. funebris: tips of oral tentacles black, penial papilla bulbiform
J. zania: tips of oral tentacles white, penial papilla minute

Best wishes,
Bill Rudman
