16 new species of Trapania

March 12, 2008
From: Bill Rudman

For those of you who may have wondered why there have been no postings this week it is because I received a new publication on Friday from Terry Gosliner & Shireen Fahey describing 16 new species of the goniodorid genus Trapania. So I have spent the last few days preparing Fact Sheets and background information, and re-organising the many un-named Trapania on the Forum which now have names. I have slight reservations about one or two of these species which I will discuss in separate messages. I have also thought it a good time to add some SEM photos of the radula of some other species of Trapania for comparison

Trapania squama   [Previously Trapania sp. 3 on Forum]
Trapania caerulea
Trapania nebula 
Trapania palmula   [Previously Trapania sp. 5 ]
Trapania scurra   [Previously Trapania sp. 6 ]
Trapania gibbera
Trapania cirrita
Trapania melaina   [Previously Trapania sp. 10 ]
Trapania euryeia   [Previously Trapania cf brunnea [in part]]
Trapania vitta
Trapania tora
Trapania armilla
Trapania darwini
Trapania naeva   [Previously Trapania sp. 1 ]
Trapania miltabrancha [Previously Trapania sp. 11 ]
Trapania circinata

This large paper does not solve all the unnamed species and identfiication problems on the Forum, but it certainly solves a lot of them. My thanks to Terry & Shireen for permission to reproduce some illustrations.
