Remarks. This species is similar to H. maricola (Fahey & Gosliner 2001) from Western Australia; it differs externally by the presence of much larger spots between the ridges and linned as opposed to spotted gills. Debelius and Kuiter (2007, pg. 235) illustrate a photograph of a Halgerda from western Australia which is externally more similar to this species than to the description of H. maricola, nevertheless without further examination of such a specimen is not possible to confirm its identity.
