Pectenodoris trilineata from Sulawesi

March 23, 2000
From: Lindsay Warren

Dear Bill
This specimen was found by Rich Smith and Doug Philpott at 6.30am on 6 June 1999 at a depth of 8.3 m in an exposed position on dead table coral on Pulau Hoga  [Tukang Besi Archipelago, SE Sulawesi, Indonesia - Operation Wallacea].  Size: 6 mm.

It looks similar to Pectenodoris trilineata but the amount of orange in the notum bands made us suspicious.  The body and foot are overall strong purple with
a thin white rim to the foot and mantle edge.  The rhinophores are a deeper orange than the notum bands with the same colour repeated in the gills.

What are your thoughts on this?
All the best

Dear Lindsay,
You are right to be suspicious where chromodorids are concerned but I am pretty sure this fits in the colour range of Pectenodoris trilineata.
Best wishes,
Bill Rudman.
