With 2 branchial spines on margin of carapace and third spine more posterior and dorsal. Intercalated spine not reaching end of antorbital spine on supraorbital eave, sitting dorsally so that eave and postorbital lobe almost in contact; with pits on sternum of male; walking legs not much longer than carapace length. Up to 5 cm long.
This species of Leptomithrax is much like L. gaimardii but only one-third as big. The carapace, rostral spines and eye orbit are similar but its legs don't extend forward much beyond the rostrum as they do in L. gaimardii. Although it is just as common as the great spider crab over a wide depth range, its denser camouflage ensures it is less commonly seen.
Intertidal, to 140 m depth.
Southern temperate oceans, including south-eastern Australia.
Not harmful but a nip from large claws could be painful
