Material examined. NMV J46931 , 1 male, Cb= 16.7 mm, Cl= 10.4 mm (acq. 20921) Survey SOL5650, Stn 063 BS020, 11°23.83'–23.81'S, 126°54.49'–54.46'E, 88– 85 m, Benthic sled, 01/10/2012 .

Colour in preservative. Front and anterolateral margins of carapace beige, with remnants brownish orange Ambulatory legs pale orange, patches of 3 R and 1P and 6L beige. Chelipeds pale orange in dorsal view and beige in ventral view with black fingers. Abdomen beige with segments 1 and 2 brownish orange.

Remarks: Widely distributed in tropical Australia, L. dodone is distinctive in the genus by its rugosities and punctuations on the carpus and external face of the cheliped palm of the male ( Serène, 1984). Lophozozymus dodone was compared with images available of specimens collected from the central Pacific (Legall and Poupin, accessed 2013) and it seems that L. dodone can have different colour patterns also in life, varying from the carapace being dark brown with the front and anterolateral margins beige to the carapace being vivid red with anterolateral margins white, differing also in the amount of white/beige on the front and anterolateral margins, sometimes with white patches that can extend until the second half of the carapace.

Lophozozymus dodone was previously only known from shallow waters (7–8 m) but is recorded here from a depth of 88 m.

Distribution. Hawaii, Tahiti, Fiji, Cocos-Keeling, South Africa, Japan (Amami Group and Ishigaki Island), Andaman Sea, and Australia (Northern Australia) ( Sakai, 1976) Depth range 7– 88 m.
