Carapace length between 4 and 9 cm. Maximum total length about 20 cm.

Interest to Fisheries:
The species has been taken occasionally during exploratory commercial fishing. Its large size makes it an attractive fishery subject, but the fact that it seems to be scarce and lives in great depths detracts from its possible commercial value.
