Trinchesia acinosa from Nelson Bay, Australia
 

Comment from the photographer: Richard Willan wrote, "Your aeolid is Trinchesia acinosa. It is characterised by the opaque white body and the orange band across the front of the head that extends laterally onto the oral tentacles. The colour of the cerata is very variable – from uniformly golden, to gold with white spots, to creamish with a golden stripe ventrally (as in your specimen). The extent of the orange colour on the rhinophores varies quite a bit too, but not as much as on the cerata.



Trinchesia acinosa is described and figured in ‘Nudibranchs of Heron Island ... ‘ on page 140 (Fig. 253), and on page 262 of ‘Undersea Jewels’. Denis Riek has a photo of it on Nudi Pixel (http://www.nudipixel.net/species/trinchesia_acinosa/), so he would have found it at Hastings Point or Brunswick Heads in northern NSW. This means your specimen is a new record for central NSW (but it’s to be expected given the reality of warming water temperatures)."
