Southern Atlantic. So far only known from two localities: southeastof the Falkland/Malvinas Islands (55°01 '-55°10'S 39°55' - 39°46'W) and south of South Georgia (60°04' - 60°08'S 35°59' - 36°04'W).
Habitat and Biology:
Deep sea between (1976-) 2068 and 2886 (-3040) m.
Total body length about 15 cm, carapace length (without rostrum) 5 to 6 cm.
Interest to Fisheries:
None so far. Until now only 4 specimens have been collected of this species. Its scarcity and the very great depths at which it is found, make it an unlikely candidate for a fishery, notwithstanding its relatively good size.
