(Fabricius, 1798)
Carpus of chelipeds with two obvious spines on distal half of outer margin. Frontal lobe spines of moderate height (mean height c. 0.04 times frontal width measured between medial orbital sutures), blunted with rounded interspaces; antero-lateral carapace spines broad, with outer margin convex. Polygonal patterning weak on chelipeds and first two pairs of legs; last two pairs of legs with stronger patterning for both sexes; patterning variable on abdomen of female, absent on male.

Antero-lateral carapace spines broad, with outer margin convex. Carpus of chelipeds with two obvious spines on distal half of outer margin, palm of cheliped with a pair of distinct spines on dorsal margin behind insertion of the dactyl. Polygonal patterning weak on chelipeds and first two pairs of legs; last two pairs of legs with stronger patterning for both sexes; patterning variable on abdomen of female, absent on male. Colour variable, similar to Scylla serrata. (Keenan et al., 1998)
