Thorunna cf. florens from South Australia
April 26, 2002
From: John Chuk
Dear Bill,
Here are images of two specimens of Thoruna cf. florens found at Rapid bay Jetty, South Australia. These are the only specimens I've seen of this species and they are identical to the specimen found by Stuart Hutchison at the same site.
UPPER: Is a specimen 14mm in length, found 31 January 2002, on a jetty pylon at a depth of 8.5m. This specimen has damage to the mantle margin and the red-brown spot on the anterior border is partially missing. At first I thought it might have been a form of Digidentis perplexa.
LOWER: Another specimen 14mm in length found on 1 February 2002. It was found actively crawling over rubble on the bottom beneath the jetty at a depth of 9m. This specimen has an intact mantle and the anterior red-brown spot is obvious.
Best wishes,
John

It is certainly consistent in colour. As I discussed with Stuart, its anatomy certainly fits that of T. florens, but as with many of these puzzles, more information is needed.
Best wishes,
Bill Rudman
