Type:
Type locality: "South China Sea, 19°40.0'N 113°41.0'E to19°39.5'N 113°36.0'E, 182-172 fathoms [ = 315-333 m), coarsesand". Holotype female in BM, no. 1965.5.21.1 (in alcohol, condition fair); paratype in RMNH, no D 21213 (in alcohol, condition good).
Geographical Distribution:
Indo-West Pacific region: Taiwan, South China Sea and N.W. Australia (off Port Hedland, Western Australia).
Habitat and Biology:
Depth range from 200 to 333 m; bottom mud and limestone rocks.
Size:
The total body length (including the antennae) of the holotype is 38 cm, carapace length 7 cm.
Interest to Fisheries:
None at present. However, the size of the specimens and the fact that they occur in not very deep wate, suggest that, once the right fishing grounds have been found, the species may be commercially exploited, like L. trigonus.
