World Distribution
Castro (2005: 519, Zoosystema) - only from New Caledonia. Depth: 320-600 m

(Castro, 2020, TDSB 31, Castro, 2005) - Papua New Guinea, Solomon Islands, Vanuatu, New Caledonia. Most specimens were collected at depths of 400-900 m, but a few juveniles at much shallower depths: 45-133 m. These juveniles could have developed from larvae that settled in unusually shallow waters, much shallower than the depths inhabited by adults.

Environnement : Marine - Substrat/Association : Hard bottom (rock and rubbles)

Vertical range : Deep (more than 100 m) - Min-Max observed: 320-600 m
