Colour in life. Carapace orange with white anterolateral margins, 1P, 2P and 3R white. Ambulatory legs orange. Chelipeds orange dorsally and white ventrally with dark brown fingers. Abdomen white (Fig. 5).

Colour in preservative. Carapace pale orange with white anterolateral margins, 1P, 2P and 3R white. Ambulatory legs light orange. Chelipeds orange dorsally and white ventrally with dark brown fingers. Abdomen white.

Remarks. Within the genus Liomera , this species is characterised by a completely divided 2M region, which makes it similar to, Liomera monticulosa (A. Milne-Edwards, 1873), Liomera rugipes (Heller, 1861) , and Liomera rubra (A. Milne-Edwards, 1865). It differs from the latter three species, which have 1M separated from the interior part of 2M. Serene (1984) describes L. margaritata with well-defined regions 4L, 5L, and 6L, but in our specimens these regions are fused and not well defined. Also, colour in live specimens are different, described as uniformly pale violet by Serene (1984), while our specimens are orange colour with white anterolateral margins. As the G1 morphology agrees well with illustrations of L. margaritata provided by Serene (1984), we conclude that the variation described above is likely to be intra-specific.

Distribution. Queensland (Great Barrier Reef, NE coast); Indo-west central Pacific Oceans ( Madagascar and Red Sea to Japan, New Guinea, Samoa, New Caledonia). Depth range subtidal– 107 m.
