The first pair equal, very slender, longer than the body, covered with sharp spinules and ending in elongate and slender fingers with long teeth on cutting edges, but without hairs. Fingers of first cheliped about as long as palm. Second pair of pereiopods very much longer than third pair.

A deep-sea species from 293 to 878 m depth (mostly between 550 and 825 m). Lives on soft mud bottoms in burrows.

Size:
Maximum total length 40 cm; carapace length 2 to 17 cm.
