These two beautiful specimens which we believe to be a species of Stiliger were found by Krzys Berkieta at about 10.30am on 25 September 1999 at a depth of 12 m on filamentous algae growing on plastic fronds suspended beneath a rompong (fish attracting device) anchored off shore in several hundred meters of water near Pulau Kaledupa [Tukang Besi Archipelago, SE Sulawesi, Indonesia - Operation Wallacea]. Size: UPPER: 6 mm, LOWER: 4 mm.
The base colour of the body is dull translucent orange. The bottom half of the many cerata are the same dull translucent orange but are also sprinkled with gold specks which sparkle, the top half of the cerata are solid black. The rhinophores and upper part of the head are black. The area around the eye spots located beneath the rhinophores on either side is dull orange and the mouth parts orange. Down the notum between the cerata is a raised ridge dusted with black. Photos: Lindsay Warren.
Is this a new one or has it already been described?
All the best

This animal is found at least in the western Pacific from Japan to eastern Australia. It was identified with Stiliger cremoniana Trinchese 1893 from the Mediterranean by Baba (1949) but to my knowledge I don't think any further attempt has been made to compare the Mediterranean and Pacific animals. In colour they are indeed very similar.
