Farhner & Schroedl's Phyllidiopsis sinaiensis

May 23, 2002
From: Bernard Picton

Dear Bill,
I just looked at Farhner & Schroedl's paper redescribing Phyllidiopsis sinaiensis after sending you a scan of the holotype. In my opinion they clearly have Phyllidiopsis krempfi not P. sinaiensis, the pictures in their paper are identical to the P. krempfi I have seen in East Africa [see separate message].

Dear Bernard,
Thanks for drawing this to our attention.
Your photo of the holotype certainly shows that it has important differences when compared with Farhner & Schroedl's description, which can be see in the photos they have sent to the Forum. The most significant one is the colour of the rhinophores, which in their animal forms a distinct black line down the posterior midline, just as in P. krempfi. Interestingly, Erwin Koehler has two sets of photos on the Forum identified as P. sinaiensis from the Egyptian Red Sea. One of these, [1997 photo] was identified by Nathalie Yonow as P. sinaiensis and like your photo does not show a black posterior midline, while a more recent 2002 photo is of an animal in which the black posterior line on the rhinophore is clearly visible. On reconsideration I would suspect this photo is also P. krempfi.
Any comments welcome,
Bill Rudman
