Solitary Ids., Coffs Harbour region, New South Wales, Australia, April 1987. 19mm long. PHOTOS: Bill Rudman.
Characterised by the radiating black lines forming a border around the mantle skirt. There is a reticulate pattern of yellow-edged ridges, and sometimes small black marks in the intervening spaces. One difference from Halgerda willeyi are the colour of the rhinophore clubs, which in that species are white with a black band around the mid-region, and in H. elegans are white with a longitudinal black band covering the posterior side of the club.
See Bergh's original illustrations of H. elegans.
