Dear Bill
We were puzzled by this Chelidonura which was found by Lucy O'Connor on 27
October 1999 at a depth of 10 m moving slowly down some encrusting coral on a wall of Pulau Hoga [Tukang Besi Archipelago, SE Sulawesi, Indonesia - Operation Wallacea]. Size: 21 mm.
The body is dark brown / black and has numerous fine light coloured spots over the central body and tails as well as the parapodia. The tails are edged in a diffuse cream band. The white band on the front of the head lacks the orange and blue markings normally seen on C. inornata. Photos: Lindsay Warren.
Is this just a variant or a separate species?
All the best

Lindsay Warren, 2000 (Mar 1) Chelidonura cf. amoena from SE Sulawesi. [Message in] Sea Slug Forum. Australian Museum, Sydney. Available from http://www.seaslugforum.net/find/1991Dear Lindsay,
It certainly looks less colourful than normal C. inornata and unlike that species this animal has white spots on the head shield and posterior shield as well as the parapodia. It also looks quite like Chelidonura amoena but the white band across the anterior end of the head is more definitively outlined in this animal than in C. amoena and in that species there is usual traces of yellow on the border. So I can suggest what it is not but I'm not too sure if it is a new species.
Cheers,
Bill Rudman.
