Pereopods 3–5 long and slender, with slender spinulose dactyls, 1 or 2 carpal spines, 5 or 6 meral spines. Abdominal somite 3 with posterior dorsal lobe. Abdominal somite 6, 1.5 times as long as wide. Total length to 165 mm.

Color in life. Bright red.

Habitat and depth. Offshore mud and sand, 550–2000 m.

Remarks. Christoffersen (1989) synonymized Pandalopsis with Pandalus Leach, 1814 ; but Komai (1994) rejected this synonymy because it was based on larval features. Because P. ampla has been reported in widely separated localities, Komai (1994) suggested that this might actually be a species complex.
