Description
White background with raised, rounded tubercles tipped in orange. Small orange specks are also scattered across the white mantle between tubercles, except around the mantle edge. Gills and rhinophores exhibit black speckles, with variable densities among individuals- some appearing wholly black, and others sparsely speckled. Similar species Halgerda aurantiomaculata lacks small orange specks across the mantle and exhibits a solid orange mantle border.

Conservation and Rarity
IUCN Status: Not Evaluated
Occurrence: Frequent (10% of sites)
Occurrence describes how often the species is found on surveys within its distribution. It is calculated as the % of reef sites surveyed by RLS divers across all the ecoregions in which the species has been observed
Abundance: Solitary (1 per transect)
Abundance is calculated as the average number of individuals recorded per RLS transect, where present.
